1. Introduction
NanoBeacon Config Tool is a Windows platform software program for testing and writing
configurations for the NanoBeacon DK (Development Kit). When testing a configuration, the
configuration is run from RAM and will execute as long as the tag is being powered. After finishing
with the testing, the desired configuration may be written to the device’s one-time programmable
(OTP) memory. NanoBeacon Config Tool software is used to configure the Bluetooth beacon
payload and related options. Figure 1 shows the overall setup.
Figure 1 Overall view of NanoBeacon device programming setup
The NanoBeacon Config tool connects to the OTP memory programmer board via USB, which has
a USB to UART adapter. The NanoBeacon tag connects to the programmer through a 8-pin
connector. The GUI of the NanoBeacon Config program is shown in Figure 2.

How to Configure and Use NanoBeacon
Step 1: Insert IN100 NanoBeacon DK board into the programmer board (make sure to follow the
orientation as shown in Figure 4) .
At this point, it is not necessary to install battery in tag (DK board) .
Step 2: Connect OTP memory programmer to PC with a USB cable. Green and red LEDs on
programmer should light. Run NanoBeacon Config Tool on PC.
Figure 4 Connect NanoBeacon DK board to programmer board
Step 3: Uncompress the ‘NanoBeaconConfigTool.7z’ file archive, locate the
‘NanoBeaconConfigTool’ application and execute it.
To control the programmer, a serial communication link must be established first by detecting the
ports, selecting the right COM port and the correct Baud rate. After selecting the right port and
baud rate, click the connect button to connect the PC with the tag.
Step 4: Obtain the configuration based on the user’s needs, and verify the configuration using the
“Run in RAM” mode, by clicking the ‘Run in RAM’ button. After clicking ‘Run in RAM’, use a scanning
device like an Android phone or tablet to see if the beacons are received. Please refer to the ‘InPlay
IN100 NanoBeacon Android Scanner User Guide’ about installing and using InPlay’s custom
NanoBeacon Android application. The Run in RAM loads the configuration into RAM and executes
it while the device is powered. To quit from the “Run in RAM” mode, ‘Close’ the UART connection,
and disconnect power from the tag by unplugging the programmer from the USB. Another way to
8 / 51
www.inplay-tech.com
IN100C0 Application Notes
quit from the “Run in RAM” mode is simply to reset the device by pressing the chip reset button in
the tag board.
After testing and verifying the configuration in “Run in RAM” mode, customers may burn the
configuration into the device’s OTP memory (Step 5). Please be noted: Configurations involve I2C
operations are not supported in the “Run in RAM” mode.
Step 5: ‘Burn’ the desired configuration into the tag’s OTP memory. The tag must be powered while
burning. A status bar shows the progress of the burning operation. If the operation is successful,
there will be a successful message popped up. If the operation fails, there will be an error
message. After burning the configuration, the power to the development board must be removed
and re-applied to start the tag executing according to its programmed behavior. A development
board’s OTP memory can only be written ONCE.
Step 6: Exit the NanoBeacon Config Tool program. Disconnect the development board from the
programmer and insert a CR1220 battery in the board to start its operation.
2. NanoBeacon config tool introduction
InPlay NanoBeacon Configuration Tool is a PC GUI (Graphical User Interface) tool for chip firmware
configuration. The PC application file is NanoBeacon Config.exe. Developers should have the
flexibility to configure the peripherals, advertising data and advertising parameters of the
NanoBeacon device (IN100) according to user’s application requirements.

Figure 5 Overview of NanoBeacon configuration tool
Figure 5 shows the general look of the GUI software tools, which consists of :
1) UART, which is used for setting UART port and baud rate on the PC to communicate
with the development kit. The default baud rate is 115200.
2) Main window, which provides a main configuration window for user to configure the
device.
3) Application Settings, which includes all configurable option tabs including Advertising
Settings, ADC, Plus Count Controller, I2C , GPIO and GPIO Edge Count. In addition, there
is an advanced mode setting for using special device behavior settings not covered in
the regular option settings. The RF Test tab provides an easy-to-use interface for users
to run various RF tests, including BLE DTM mode test and carrier test.
4) Global settings, which provides settings to the device that applies to all advertising
sets.
5) Current Settings, which provides an overview of device settings and configurations.
6) Configuration, which provides the user with a way to save the configuration to a file or
load it from an existing configuration file. Once the configuration file is successfully
loaded, the user has two options to try and test the configuration on the device. One is
10 / 51
www.inplay-tech.com
IN100C0 Application Notes
"Run in RAM", which provides a way to test and verify the user's configuration before it
is permanently burned to the device. Whenever there are any changes to the
configuration, the user should always reset the device before operating "Run in RAM".
The other is "Burn/Program" which will permanently burn the configuration file to the
device, which is irreversible and should be performed as the last step.
7) Advanced Debug Settings, which provides a way to read/write device’s
register/memory/eFuse and this is used for debugging purposes only.
2.1 Advertising sets configuration
2.1.1 Overview
The IN100 device supports up to three advertising sets: Advertising set #1, #2, and #3 which can
be individually configured by using the NanoBeacon configuration tool through Advertising set
#1, Advertising set #2 and Advertising set #3, respectively.
The overall brief configuration settings tab page for each advertising set is shown in Figure 6.

The "Show QR Code" button will provide a QR code which is the advertising address information for
the user's mobile application to easily identify and parse data from advertisers.
The “Global Trigger Settings” allows users to set trigger conditions that apply to all advertising
sets.
The "Customer Product ID" is a unique ID that can be assigned to each device. It can be used like a
serial number, for example, to assign a unique number to each device during the manufacturing
process. In our payload data field information, it is referred to as "CustID".
2.1.2 Advertising set configuration
The main window provides users to access to all possible configuration parameters for their
application requirements including Advertising Data, Advertising Parameters and Advertising
Mode, as shown in Figure 8.

Advertising data format
The NanoBeacon config tool supports both standard BLE packet data configuration through AD
structures and user defined configuration completely controlled by user.
Figure 9 shows the advertising data format. It consists of multiple BLE standard AD structures
and/or multiple user defined data sections. It should be pointed out that the advertising data can
just consist of as simple as one AD structure or one user defined data section. The standard BLE
AD structure consists of a Length field of one byte, which contains the Length value, and a Data
field of Length bytes. The first byte of the Data field is the AD type field. The content of the
remaining Length - 1 bytes is called the AD data.

The tool supports three commonly used Advertising data formats.
• iBeacon, Apple proprietary Beacon advertising frame format based on Bluetooth standard
advertising.
• Eddystone, a Google proprietary Beacon advertising frame format based on the service
data of the Bluetooth standard advertising.
• Custom, an advertising data in a custom user-defined format.
1) In case of the “iBeacon Advertising Settings”, the user needs to fill in the followings:
o UUID: Application developer should define a UUID specific to their app and
development use case. The default value is E2C56DB5-DFFB-48D2-B060D0F5A71096E0.

a sub-region within a larger region defined by the UUID.
o Minor: Allows further subdivision of region or use case, specified by the application
developer.
o Measured Tx Power: Apple recommends measuring the RSSI of the advertising beacon
at a constant distance of 1 meter at multiple positions, then applying the average
measured RSSI value to the beacons transmit power.
2) In case of the “Eddystone Advertising Settings”, the user needs to follow the Eddystone
protocol and configure the device:
o For details, please refer to Google Eddystone protocol specification at
https://github.com/google/eddystone/blob/master/protocol-specification.md.
3) In case of the “Custom Advertising Settings”, the user can configure the below based on their
application needs:

IN100C0 Application Notes
Note: Please refer to 2.1.2.3 for details on data encryption and authentication.
2.1.2.2 Advertising data configuration
The Advertising data consists of multiple user defined data sections.
To add a user defined data section to the advertising data, select data format from one of the
three data formats below.
• iBeacon.
• Eddystone.
• Custom.
1) Enter one data segment:
o If it is predefined data, user can directly type in the data entry box. Note: Only
hexadecimal data is supported where 2 characters represent one byte.
o If it is extended data, we can select the data from the drop-down list from Dynamic Data
box and then press button “Append to Data”. The added extended data will be shown in
the data entry inside “<>”, as shown in Figure 12. For most of the extended data, the user
can configure the number of bytes to be advertised. For example, the “Adv Count”
(advertising count) internally has 4 bytes. A user can configure the device to advertise
only 2 LSB bytes only by changing the number of bytes to 2. Depending on the data
source selected, the endianness, encryption option and Trigger Snapshot option can
be selected collectively or respectively.
2) Repeat the 1
st
step as necessary.
3) After finishing configuration of the data segment, click the “OK” button in the “Advertising Data”
tab to add the data to the Advertising Data . Note that each standard AD type can only be added
once while user defined data type can be added multiple times. Note: For the standard BLE
AD structure, the length field and AD type are automatically added to the advertising data once
we press the “OK” button.

2.1.2.3 Advertising data encryption and authentication
The NanoBeacon device supports simultaneous encryption and authentication to the advertising
data, based on the AES-EAX encryption algorithm (M. Bellare, P. Rogaway and D. Wagner. "EAX: A
Conventional Authenticated-Encryption Mode", 2003). Each of three advertising data sets can be
individually and independently configured regarding whether user needs to enable encryption
and/or authentication.
The AES-EAX engine
To enable encryption and authentication, in the device, the user needs to specify the following
inputs to the AES-EAX engine for each advertising set.
• A single 16-byte key used for both encryption and authentication.
• The selected data portion (plain text) in the advertising data to be encrypted.
• A 6-byte nonce.
• The number of bytes for the message authentication code (MAC, usually called as a tag).
The outputs of the AES-EAX engine are:
• The encrypted data (ciphertext), which has the same length as the plain text.
• The tag.
Figure 13 illustrates the advertising data without and with encryption/authentication. We assume
the data portion 2 needs to be encrypted and authenticated. The salt in the figure is a part of 6byte nonce.
19 / 51
www.inplay-tech.com
IN100C0 Application Notes
The salt and the tag are optional, and they are not required to be present in the advertising data.
• If the intended receivers know what the salt is used, then customers can select not to
present the salt in the advertising data through the NanoBeacon Config Tool.
• If the user does not need authentication, then the user can select not to present the tag
in the advertising data through the NanoBeacon Config Tool.

Figure 13 Advertising data encryption and authentication
To enable encryption and authentication for the specific data field in each advertising set, the
user needs to check the “Encrypt” box as shown in Figure 14.
Figure 14 Encryption enabling
Keys
The AES-EAX needs a 16-byte key for the encryption and authentication for each advertising
set. There are three keys (key0, key1 and key2) to be chosen from, as shown in Figure 15.

IN100C0 Application Notes
Figure 15 Selection of key and key for AES-EAX
The configuration of the three key is in the “Global Settings as shown in Figure 15. The input box
of the corresponding key needs to be filled with hexadecimal data.
Nonce
The 6-byte nonce consists of a 2-byte salt and a 4-byte counter (we refer this counter as nonce
counter). The device offers a variety of selections for the salt and the counter.
1) Nonce Salt
There are two selections available for the salt as shown in Figure 16:
• Random number: The salt will change every advertising.
• Predefined fixed number.
If the receivers know the salt, it does not need to be advertised. If the salt is a random number, we
need to include the salt in the advertising data as a plain text, which is shown in Figure 16.
21 / 51
www.inplay-tech.com
IN100C0 Application Notes
Figure 16 Including the AES-EAX salt in the advertising data
2) Nonce counter
There are multiple selections available for the nonce counter as shown in Figure 16:
• Time Stamp 1: The device has a 32-bit second counter. It starts counting from 0 upon
power cycle.
• ADV Count (Advertising counter): The device provides an advertising counter for each
advertising data set. When an advertising set is advertised over the air, the corresponding
counter increases by 1. Upon power-cycle, the counters are initialized to 0.
• Predefined fixed number.
To achieve maximum security and privacy, it is recommended to use real-time varying numbers
(like second counter, 100-ms counter, advertising counter and random number) for the nonce
counter instead of the fixed numbers (like static random number and predefined fixed number).
Normally, the nonce counter is not advertised in the advertising data. If the selected nonce counter
is the Time Stamp 1 (second counter), the receivers may resolve the nonce counter using the
algorithm discussed by A. Hassidim, Y. Matias, M. Yung, and A. Ziv, “Ephemeral Identifiers:
Mitigating Tracking & Spoofing Threats to BLE Beacons”, 2016. To that end, the device supports
Advertising of ephemeral identifier (EID).
The resolution of the nonce counter is complicated and requires intensive computation. To bypass
these issues, the nonce counter can be part of the advertised data in plain text. Figure 17 and Figure
22 / 51
www.inplay-tech.com
IN100C0 Application Notes
18 show how to include the nonce counter in the advertising data where the nonce counter is the
second counter and the advertising counter, respectively. Please be noted, the “Big Endian” box
must be checked for the corresponding item selected as the nonce counter. If the receivers know
the nonce counter, then it does not need to be included in the advertising data. For example, if we
select to use a predefined fixed number.

Selection of advertising data to be encrypted
Part of the advertising data can be encrypted and authenticated. In this section, we describe how
to configure the data to be included in the encryption and authentication. Please be aware that

2.1.2.4 Advertising parameters configuration
The user can configure advertising parameters through “Advertising Parameters” tab window
including:
• Advertising Interval: Used to define the rate at which the Advertising Set will send out
advertising packets in milliseconds.
• PHY Selection: Defines the PHY used for sending out the advertising data packets. LE 1M is
the most used and supported by Bluetooth devices. LE Coded PHY is typically used for longrange communication but is not widely supported by other Bluetooth devices.
• CTE: Once checked, the device will automatically add a Constant Tone Extension to the
advertising packet. The CTE duration unit defined by Bluetooth Core specification is 8us, and
user can choose the CTE duration range from 2 to 20 which equivalent to from 16us to 200us.
• Advertising Channels: Determines the RF channels used to send advertising data on. User
needs to select at least one channel.

Figure 27 Advertising mode selection
Continuous advertising mode
In the continuous mode, NanoBeacon™ advertises periodically according to the interval set by
advertising interval.
Triggered advertising mode
In the event trigger mode, NanoBeacon™ device advertises once an event is triggered according
to the trigger parameters. The user can configure the number of advertising events sent out due to
the occurrence of a trigger event through entering the “Advertising Event Count”. “Trigger will reset
advertising event count” enables resetting of the advertising event count whenever a Trigger
condition is met at each enabled advertising event.
The device can have multiple sources used to trigger advertising. It also supports different
advertising behaviors (modes) after an event is triggered as listed below.
• Single Trigger: Configures the device to advertise based on the occurrence of a single
trigger event (caused by any trigger condition being met). Subsequent trigger events will
not cause the device to advertise unless the device experiences a power reset.
• Recurring Trigger: Configures the device to advertise based on the occurrence of a
trigger event (caused by any trigger condition being met). The device will initiate the
advertising again based on any subsequent trigger events.
• Advertise Indefinitely after 1
st
trigger: Enables the device to continue advertising
indefinitely at each advertising interval after any trigger condition is met.

Event trigger source
The event trigger source can be sensor inputs or GPIO states.
i) Sensor inputs
The device totally supports up to 4 sensor inputs as trigger sources (Trigger 1, Trigger 2, Trigger 3
and Trigger 4). User can go to “Global Trigger Settings” to configure them. If the digital samples of
selected sensors are over or below the pre-specified thresholds, advertising will start.
Each of senor input trigger source (triggers 1, 2, 3 and 4) can be selected from the followings:
• VCC
o The VCC is the supply to the device’s VCC pin.
o Low Threshold setting only. The input value unit can be determined through “On-
Chip Measurement Units” settings as shown in Figure 28 and Figure 29.
Figure 28 On-Chip measurement units
Figure 29 On-chip temperature and VCC unit setting
o Threshold value = Desired threshold value / On-chip VCC unit. Integer input only. For
example, if user wants the device to start advertising when the VCC is below 2.5V,
then the threshold value should be 2.5/0.03125=80.
• ADC CH0
o This is for the analog channel # 0 connected to the MGPIO-4 pin in the device.
o The ADC inside the device converts the analog signal (Vin) presented on a mixed
signal pin to an ADC code with range from 0 to 2047 according to
Raw ADC code = Vin/Vref *1024
where Vref is the internal reference voltage, and it is equal to 0.8V. The analog
input signal’s range is from 0 to 2*Vref. Note:
The raw ADC code readout will
deviate from the desired result due to DC errors such as offset, ambient
temperature, differential non-linearity (DNL) and integral non-linearity (INL).
30 / 51
www.inplay-tech.com
IN100C0 Application Notes
o By mapping default, the customers can convert the thresholds in voltage to the
corresponding ADC code values and enter the ADC values as thresholds in the
configuration tool. Assume a customer wish to let the device start advertising
when the analog signal on the MGPIO-4 pin is below 0.4V or is above 1.2V. The low
threshold would be ADC code = 0.4/0.8*1024 = 512, and the high threshold would
be ADC code =1.2/0.8*1024=1536.
o
The device supports linear conversion between two different units of
measurements. The ADC of the device measures the voltage from a sensor output.
If the customers want to have the advertising data to be broadcasted in a different
unit instead of raw ADC code (raw ADC code = Vin*1024/Vref where Vref =0.8V),
they can achieve that by appropriately configuring the unit mapping parameters.
For example, a temperature sensor outputs 1.4V when the temperature is 100
Celsius degree, and outputs 0.4V when -10 Celsius degree. In addition, they want 1
LSB (least significant bit) in the advertising data to represent 0.1 Celsius degree.
In that case, the unit should be 0.1, the value of 1.4V should be 100, and the value of
0.4V should be -10 as shown in
Figure 30
. Please be noted, only linear conversion
is supported. When non-default mapping is used, the thresholds to trig advertising
should be calculated according to the new mapping. Taking the above
temperature mapping as an example, if a customer wants the device to advertise
when the temperature is below -8 Celsius degree or is above 90 degree, the low
threshold should be -8/0.1=-80, and the high threshold should be 90/0.1=900
where 0.1 is the unit that the customer wants.

IN100C0 Application Notes
o These are the analog channels connected to the MGPIO-5, MGPIO-6, and MGPIO-7,
respectively.
o The configurations for these channels are similar to the configuration for ADC CH0.
• 1-Wire Sensor
o The number of pulses counted received by the device can be entered as threshold
value. Integer input only.
• Internal chip temperature.
o Device integrated an internal temperature sensor and user can set the threshold
based on the desired temperature value. The input value unit can be determined
through “On-Chip Measurement Units” settings.
o Threshold value = Desired threshold value / On-chip temperature unit. Integer
input only.
• I2C Slave #1 and I2C Slave #2 : Support only 16bit 2’s complement format of data.
Figure 31 Sensor trigger source
The digital sample of each of the triggers can be configured to compare with certain thresholds
and can be configured as shown in Figure 31.
• Trigger 1 Low Threshold: Trigger 1 triggers an advertising when the sample is below its set
threshold, and Trigger 1 only has a low threshold comparator.
• Trigger 2 High Threshold: Trigger 2 triggers an advertising when the sample is above its set
threshold.
• Trigger 2 Low Threshold: Trigger 2 triggers an advertising when the sample is below its set
threshold.
32 / 51
www.inplay-tech.com
IN100C0 Application Notes
• Trigger-3 High Threshold: Trigger 3 triggers an advertising when the sample is above its set
threshold.
• Trigger 3 Low Threshold: Trigger 3 triggers an advertising when the sample is below its set
threshold.
• Trigger 4 High Threshold: Trigger 4 triggers an advertising when the sample is above its set
threshold.
• Trigger 4 Low Threshold: Trigger 4 triggers an advertising when the sample is below its set
threshold.
To enable sensor input-based event trigger, we need to set the event monitoring period which is
set by the “Trigger Check Period” item of the GUI Tool Trigger Advertising Settings as shown in
Figure 32.

ii) GPIO states
The device supports GPIO level (high or low) or edge (rising or falling) trigger. To enable the GPIO
trigger, check the corresponding GPIO as shown in Figure 33. The supported trigger modes are
low level trigger, high level trigger, rising edge trigger and falling edge trigger which can be
configured in the “GPIO” settings tab. The GPIOs selected for event trigger must be configured as

Unit Mapping Calibration
If the data of the external analog sensor is linear with the voltage, the device can directly convert
the data into the unit of the analog sensor. If it is not a linear relationship, please keep the data
unchanged, and the advertising data (Raw ADC code as shown below) is hexadecimal data in mV.
Raw ADC code = Vin/Vref * 1024, where Vref = 800mV (internal reference )
The default unit mapping is as shown in Figure 35 with unit of 0.78125mV per LSB. For instance, if
the advertising data for ADC read out is 0x400 (1024 in Decimal) , the Vin is equal to:
Vin = 1024 (ADC code) * 0.78125mV = 800mV.
35 / 51
www.inplay-tech.com
IN100C0 Application Notes
The user can also configure the Unit Mapping for the sensors which has the linear relationship
with ADC read out. And in such case, a linear conversion can be automatically executed on chip
for the result to be presented in the advertising data.
For example, a temperature sensor outputs 1.4V when the temperature is 100 Celsius degree, and
outputs 0.4V when -10 Celsius degree. And 1 LSB (least significant bit) is used in the advertising
data to represent 0.1 Celsius degree. In that case, the unit should be 0.1, the value of 1.4V should
be 100, and the value of 0.4V should be -10.

Sampling Configuration: ADC sampling parameters, generally use the default parameters. In
special cases, the parameters such as “Number of Samples to Skip” and “Number of Samples to
Average” are adjusted according to the external analog device.
When “Enable” is checked for certain ADC channel, the digital GPIO function corresponding to the
multiplexed pin needs to be turned off, and pull-up and pull-down need to be turned off. See the

2.4 One-wire sensor interface configuration
The device integrates a one-wire (single-wire) pulse count controller and interface which can be
used to interface a one-wire pulse sensor. There are many sensors which convert the measured
physical quantity into number of pulses. The one-wire controller can provide power management
and 16-bit pulse counting at the same time. Figure 39 shows the timing of power management and
pulse counting sequence. Typical conversion time is from 30 to 60 ms, and pulse output time is
from 30 to 60 ms (please check out the one-wire sensor that is being used). In the figure, tp is the
period of a pulse, typically from a few us to a few tens us. The total time and the maximum period
of a pulse can be configured by the configure tool. The device has two power switches which can
be used for the power management of the sensor.

Figure 41 I2C configuration tab
The user can configure the following items related to I2C salve device.
• PIN Select: Select the pins corresponding to SCL and SDA of I2C devices according to the
actual circuit. The Device’s GPIO2/3/4/5/7 can be used as SCL and SDA of I2C interface.
• Address Mode: Supports 7bit and 10bit mode.
• I2C Speed: The device supports 100KHz and 400KHz clock rate.
• Slave Address: The user can enter the I2C slave device address in the box.
• Read Data Storage Settings: I2C read will store the data into the device’s internal memory
with the starting address at 0x2300; Offset is the offset of the address, the default setting
is 0 for I2C Slave #1, 16 for I2C Slave#2 and 32 for I2C Slave #3 respectively; Length is the
length of the I2C data read out memory length, and the unit is byte; I2C read data will be
automatically wound up when the length exceeds the defined “Length”.
I2C Commands
To drive external I2C slave device, an I2C communication protocol shall be defined and configured
for both devices to establish the I2C communication with each other. The NanoBeacon Config Tool
provides the “I2C Commands” input tool for such purpose.
Figure 43 shows the main configuration window for I2C Commands input. There are 4 commands
available:
• I2C read: For this command, we need to specify the number of readings (r_len) from the
slave in the GUI. The maximum r_len is 5. If more than 5 bytes read needed, the user needs
to configure I2C reads multiple times separately.
40 / 51
www.inplay-tech.com
IN100C0 Application Notes
• I2C write: For this command, we need to specify the byte sequence written to the slave in
the GUI. If more than 5 bytes need to be written, then the user needs to configure I2C writes
multiple times separately.
• I2C write_stop_read: For this command, the user need to specify the byte sequence to be
written to the I2C slave device as well as the number of readings (r_len) from the slave in
the GUI.
• Delay command: the users can use this command to insert delay or wait time between I2C
commands, or delay/wait time before an I2C command.
The execute condition for the above commands can be configured individually using the check
box “Execute I2C command when cold boot” (the cold boot only box) or “Execute I2C command
when warm boot” (the warm boot box).
In typical application, the device switches its state between wakeup/active and sleep, as shown
in Figure 42 . The first time going into active upon power-on is called cold boot, and the wakeups
after sleep are called warm-boot.
Active Sleep Wakeup/Active Sleep Wakeup/Active Sleep
Power on
Cold boot
Warm boot
Time
Warm boot
Figure 42 IN100 states
Execute I2C command when cold boot: Execute I2C read/write command when cold boot. If only
this execution condition is checked, then the corresponding I2C command will be executed only
once when the chip is cold booted, which is often used for the initial configuration of the I2C
device.
Execute I2C command when warm boot: Indicates that the chip executes the I2C read/write
command described above when it goes from sleep to wake up. When the device does not
advertise data, it tends to go into sleep state, and when it needs to advertise, it first wakeup and
then advertise. The loop flow is wakeup -> advertise -> sleep. So, it can be simply understood that
if this option box is checked, then the corresponding I2C commands will be executed once for
each wakeup event.
If the commands are only needed to be executed during cold boot, then we need to check the cold
boot only box.

IN100C0 Application Notes
Figure 44 GPIO configuration tab
The GPIO options are input, output, and disable. If the GPIO pin is used as an analog input to the
ADC, you must select disable to turn off the digital function. If the GPIO pin is used as an input
source for the pulse controller, then input must be selected, and the default is input.
Pull-up options are pull up, pull down and disable, which correspond to pull up, pull down and
neither pull up nor pull down.
Disable must be selected if the GPIO pin is used as an analog input to the ADC, otherwise select as
needed. The default is pull-up.
Adv. Trigger options are disable, high level, low level, raising edge and falling edge, which
correspond to off trigger, high level, low level, rising edge and falling edge trigger advertising. Use
with the GPIO Trig Source on the Advertising Data Settings configuration window. To enable GPIO
ADV trigger, the corresponding GPIO needs to be set to input.
Wakeup has disable, high level and low level. disable is not to enable GPIO wakeup, high level is to
wake up the chip when GPIO is high level, low level is to wake up the chip when low level.
Latch is used to keep a GPIO state when the device going sleep and out of sleep. By default, when
the device is in sleep, the GPIO’s default state is in “high-Z” state, and upon wakeup, its default
43 / 51
www.inplay-tech.com
IN100C0 Application Notes
state is input with pull-up. For most of application cases, the ConfigTool handles the latch
automatically, and users do not need to do anything. Some typical cases are:
• If a mixed GPIO is configurated as an analog channel input pin, that GPIO will be
automatically disabled, and latched.
• If a GPIO is configured as an input wakeup pin, that GPIO will be automatically latched at
input mode.
If a GPIO is configured as an output low or output high, and users want that GPIO to keep the state
during sleep, users should enable latch for that GPIO.
2.7 Advanced Settings
Advanced mode settings are available for users when the regular GUI tool configuration options
do not meet their specific application needs. A special support channel is available through the
advanced register settings provided by InPlay support engineers. Always consult the InPlay
support team before making any changes in this mode. Changes made here may override
settings in other parts of the tool.
