New features include:

 Longer life from a CR2032 battery  Longer range (up to 200m LOS)  Over-the-air configurability  Multiple interleaved packet types  Modular RF certification  Optional connector for sensors or power source

The EMBC22 is compatible with all major beacon formats including iBeacon™, Eddystone™, AltBeacon™ and compatible with Quuppa Intelligent Locating System™. The beacon is fully customizable over the air or in production. For example, the following parameters can be easily modified:

 Packet types, including custom packet type  Device name, address, manufacturer name, model

number, HW/SW revision

 UUID, Major/Minor ID, UID or URL  Beacon interval, Transmitter power  Accelerometer function and sensitivity

The EMBC22 can be shipped pre-programmed with custom firmware or custom parameters and can be securely updated in the field with over-the-air programming from a

mobile device (all major iOS® and Android™ devices

supported). The EMBC22 accelerometer can be used to implement

efficient and low-energy algorithms for various applications. The accelerometer can be used to activate beaconing on movement, or gestures, for example. When not active, the beacon dissipates minimal energy.

The EMBC22 can be stored in off mode without significantly degrading the battery lifetime. When active for 8 hours per day and configured for 0dBm output power and 1 second advertising intervals, the battery lifetime is more than 4 years.

The EMBC22 can be delivered in any quantity with guaranteed unique ID. A 2D unique serial number is printed on the beacon housing for optical scanning.

The EMBC22 is also available in PCB module format without housing. The module comes with the switch and battery holder. The beacon comes standard with a Renata CR2032/ 225mAh battery. Other Renata Lithium primary batteries such as CR2016/90mAh, CR2450/540mAh and CR2477/950mAh can also be accommodated.

The EMBC22 comes in a waterproof housing, and operates over a -20C to +60C temperature range. The EMBC22 is modular Bluetooth V5.0, FCC, IC, and CE certified, RoHS and REACH compliant.

The hardware features of the button, Red LED, Green LED and Accelerometer may be disabled in firmware.

The option to disable these hardware features is unavailable in the standard release of the EM9304 Beacon

Configuration Tool Suite. Options to control these features are made available on request in EM9304 Beacon

Configuration Tool Suite.

6.4.7 Operating Modes

Operating Modes of the EMBC22 are indicated with boxes in the Figure 3: Firmware State-Diagram. The

modes are fixed unless code patches are written and applied to redefine the states. Code patches may be

developed using the EM9304 Beacon SDK on the EMBC22 DVK. Behaviors within specific states, such as

advertisement profiles in the Beaconing Mode, can be redefined using the EM9304 Beacon Configuration

Tool Suite. No source code development is required when using the EM9304 Beacon Configuration Tool

Suite.

6.4.7.1 Power-On-Self-Test (POST)

On battery insertion, a self-test feature is run to confirm functionality of the key electrical components for advertising. The test sequence follows the flow listed below:

1. Test the 32kHz crystal operation, red and green LEDs on

2. Test the 48MHz crystal operation, red LED on

3. Test the accelerometer, green LED on

4. LEDs off If the test passes, both LEDs will turn off. If the test fails, one or more of the LEDs will remain on in the present state to indicate which step failed.

6.4.7.2 Startup Mode

The startup mode is the mode that will be entered after POST or on a Config Timeout Event. The default definition of Startup Mode and reassignment options are as defined in Table 5: State Machine Configuration Options.

6.4.7.3 Warehouse Mode

In Warehouse Mode, the EMBC22 is in its lowest consumption state to support long term storage. A Config Event, On/Off Event and Lock Event will all initiate exiting the Warehouse Mode. If a Config Event or On/Off Events are defined to use the flip option, the accelerometer will be sampling at the rate defined in the accelerometer configuration settings and the consumption will increase as defined in the Table 8: Accelerometer Configuration Options at the selected sampling rate. If the Config Event and On/Off Event are not defined to use the flip option, the accelerometer is in a power down state and the consumption of the device is as defined in Section 4.3.

6.4.7.4 Configuration Mode

In Configuration Mode, the EMBC22 advertises a connectable advertisement at the default interval and output power as defined in Table 6: Configuration Mode Advertisement Configuration Options. The advertisement rate and output power may be redefined by the user. The configuration timer is started on entry into the Configuration Mode. If no connections are made before the Config Timeout occurs, the EMBC22 returns to the startup state. Exit from Configuration Mode is initiated by an On/Off Event, Lock Event or Config Timeout. When a connection is made to the EMBC22, the part will stay in a connected state until the master breaks the connection or is out of range. On disconnect, the EMBC22 initiates a reset and returns to the POST state.

Figure 4: Example of three advertisements enabled

The beacon engine combines these three independent advertisement definitions to create appropriate interleaved advertisement profiles based on the Activity Events detected. The part is in an Inactivity Mode until an Activity Event is detected and the beacon engine manages interleaving the advertisement profiles is as shown in the figure below.

Figure 5: Example advertisement interleaving in Inactivity Mode

Once an Activity Event is detected, the beacon engine reengages to disable the On When Inactive advertisement and enable the On When Active advertisements. The resulting interleaved advertisement for profile in this example is shown below.

When multiple advertisements are running in parallel timing collisions may occur. The firmware will make priority decisions regarding which advertisement to send next. The advertising interval of one or more packets is extended by a minimum of 30ms when collisions occurs in order to prevent violation to BLE advertisement protocols.

6.4.8 Mode Transitions

Mode transitions of the EMBC22 are indicated with arrows in the Figure 3: Firmware State-Diagram. The start and ending mode of transitions are fixed unless code patches are written and applied. Code patches may be written using the EM Beacon SDK and developed on the EM Beacon DVK. The duration of a Config Timeout or an Activity Timeout can be redefined using the EM Beacon Configuration Tools. Additionally, the source of the Config Event and On/Off Event can be redefined using the EM Beacon Configuration Tools. No source code development is required when using the EM Beacon Configuration Tools.

6.4.8.1 Config Event

6.4.8.2 Config Timeout

6.4.8.3 On/Off Event

6.4.8.4 Activity Event

Activity Mode is a subset of Beaconing Mode. When advertisements are assigned to this Advertisement Gating option, the advertisement will only occur after an Activity Event has been detected and for the duration of time defined by the Activity Timeout. Advertisements assigned to the Always Enabled advertisement gating option will continue to be transmitted while in the Activity Mode.

Inactivity Mode is a subset of Beaconing Mode. When advertisements are assigned to this advertisement gating option, the advertisement will only occur when not in the Activity Mode. Advertisements assigned to the Always Enabled advertisement gating option will continue to be transmitted while in the Inactivity Mode.

A connection can be initiated from any mode where a connectable advertisement is sent. When a connection is made, all accelerometer interrupt sources are disabled. If the connection was made from Configuration or Activity Mode, the correlating timer continues to run while the connection is enabled. If the corresponding timer expires while the connection is enabled, the timeout event will occur on disconnect. Pressing the button during a connection will initiate a disconnect. If the corresponding timer does not expire while the connection is still enabled, the mode that the connection was initially made in will resume on disconnect. Specific services may initiate a Reset Event. A Reset Event will return the part to POST.

A Config Event generates a transition from the Beaconing Mode or Warehouse Mode into Configuration Mode. The Config Event may be assigned as defined in Table 6: Configuration Mode Advertisement Configuration Options using the EM Beacon Configuration Tools. No source code development is required when using the EM Beacon Configuration Tools.

The Green LED flashes twice when a Confg Event occurs.

On entry into the Configuration Mode, the configuration timer is started. A Config Timeout is generated when that timer expires and initiates a transition from Config Mode to the startup mode. The duration of the Config Timeout may be modified with the EM Beacon Configuration Tools as defined in Table 6: Configuration Mode Advertisement Configuration Options. No source code development is required when using the EM Beacon Configuration Tools.

The Red LED flashes twice when a Config Timeout occurs.

An On/Off Event generates a transition from the Beaconing Mode to Warehouse Mode, from Configuration Mode to Beaconing Mode and from Beaconing Mode to Warehouse Mode. The On/Off Event may be modified as defined in Table 6: Configuration Mode Advertisement Configuration Options using the EM Beacon Configuration Tools. No source code development is required when using the EM Beacon Configuration Tools.

When the On/Off Event initiates transitioning to Beaconing Mode, the Green LED is enabled while the event is occurring. When the On/Off Event initiates transitioning to Warehouse Mode, the Red LED is enabled while the event is occurring.

An Activity Event generates a transition from the Inactivity Mode to Activity Mode. The Activity Event may be assigned as defined in Table 6: Configuration Mode Advertisement Configuration Options.

No LED indicators are used to communicate transitions between Activity and Inactivity Mode.

6.4.9 Accelerometer Configuration

Configuration of key control registers on the accelerometer may be modified from the EM Beacon Configuration Tools. The configurable options are listed in Error! Reference source not found.. Description f the parameter are from the STM LIS2DWL datasheet DocID029682 Rev4. Additional details regarding the impact on the operating behavior, consumption and performance of the device can be found in the accelerometer datasheet.

On entry into the Activity Mode, the activity timer is started. An Activity Timeout is generated when the activity timer expires and initiates a transition from Activity Mode to the startup mode. The duration of the Activity Timeout may be modified with the EM Beacon Configuration Tools as defined in Table 6: Configuration Mode Advertisement Configuration Options. No source code development is required when using the EM Beacon Configuration Tools.

No LED indicators are used to communicate transitions between Activity and Inactivity Mode.

A Reset Event is initiated by battery insertion, toggling the enable signal from the test bus or from select BLE services. A Reset Event clears data RAM and returns to the POST state to reinitialize the part.

After a Reset Event the LED indicators of POST running will be seen.

A Lock Event will disable the On/Off Event and initiate a transition to Beaconing Mode. The only way to exit beaconing mode after an On/Off Event has been initiated is to issue a Reset Event.

The Green LED flashes three times when a Lock Event has been initiated.
