1. Introduction

1.1. Overview

Parani-SD is a terminal device for wireless serial communication usingBluetooth technology that is an
international standard of short range wireless communications. Parani-SD can communicate with other
Bluetooth devices; user may connect other Bluetooth devices that support the Serial Port Profile.

Parani-SD provides several models with different communication ranges, from30m (Parani-SD200) up
to 100m (Parani-SD100) for various applications.

Parani-SD has a compact design, which allows it to be placed conveniently into various devices or
equipment. Its detachable antenna has the ability to optimize the quality and distance of wireless
communications.

Parani-SD supports FHSS (Frequency Hopping Spread Spectrum), which is a technique, native to
Bluetooth that allows the Parani-SD minimize radio interference while decreasing the likelihood of
over-air hijacking. Parani-SD also supports authentication andBluetooth data encryption.

Parani-SD can be configured and controlled by a set of AT commands. Users can easily configure
Parani-SD on a terminal program, such as HyperTerminal, and configure for wireless communication
without modifying user’s existing serial communication program. User friendly ParaniWIN can also be
used for easy setup on Microsoft Windows.

Note *:

Bluetooth v1.2 supports improved AFH function. AFH function is to mitigate the interference
between WiFi and Bluetooth radios by automatically avoiding the active WiFi channel from
Bluetooth link. However, AFH does not provide a complete solution making WiFi and Bluetooth
work together in harmony. It is highly recommended for users to test their wireless system
enough before deployment since the overall system performance is affected by various
environmental factors such as distance between them.

3. Configuration

3.1. Operation Modes

In addition to the serial port configurations, the Parani-SD requires also includes some settings for
Bluetooth. For getting the most out of Parani-SD, user should understand the following Bluetooth
connection schemes.

A Bluetooth device can play a role as a master or slave. Master tries to connect itself to other
Bluetooth devices, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth
connection is always made by a pair of master and slave devices. A slave can be in two modes,
Inquiry Scan or Page Scan mode. Inquiry Scan mode is waiting for a packet of inquiry from other
Bluetooth device and Page Scan mode is waiting for a packet of connection from other Bluetooth
device. Every Bluetooth device has its unique address, called BD (Bluetooth Device) address, which is
composed of 12 hexa-decimal numbers.

Parani-SD has 4 operation modes as follows. Each mode can be identified with LED indicators as
illustrated in next section.

Table 3-1 The Parani-SD Operation Modes

Mode Description
Mode0 In this mode, there is no response when power onorsoftware reset, and Parani-SD is just

waiting forAT command input.Neither master nor slave is assignedto Parani-SD in mode0.
User can change the configuration parameters of Parani-SD in this mode.

Parani-SD must be in Mode0, whenitis directly controlledbyAT commands.
The factory defaultis set to Mode0.

Mode1 Parani-SD tries to connect the last connectedBluetoothdevice.

Parani-SD in Mode1 is to be a master and tries to connect the last connected Bluetooth
device. Parani-SD always stores the BD address of the Bluetooth device to which Parani-SD
has connected last. WhenParani-SD is initiallyused or after hardware reset, there is no BD
address stored in Parani-SD. In this case, Mode1 willnot be able to work properly.Themode
change to Mode1 can be made after Parani-SD succeeds to connect to one other Bluetooth
device. Once changed to Mode1, Parani-SD will try to connect automatically the last
connected Bluetoothdevice whenever the unit is powered on or software reset.
Parani-SD in Mode1 cannot be discovered or connected by other Bluetoothdevices.

Mode2 Parani-SD is waits for a connectionfrom the last connected Bluetooth device.

Parani-SD in Mode2 is to be a slave and waiting for the connectiononlyfrom the last
connected Bluetoothdevice. Just like Mode1, if there is no BD address stored in Parani-SD,
the mode changefrom other operation modes to Mode2 is not work properly.Oncechanged to
Mode2, Parani-SD will wait for the connection from the last connected Bluetoothdevice
whenever the unit is powered on or software reset.
Parani-SD in Mode2 cannot be discovered or connected to Bluetoothdevices other thanthe
last connected device.

Mode3 Parani-SD is waiting for the connection from anyotherBluetooth devices.In Mode 3 the

Parani-SD is discoverable and canbe connected to byother Bluetoothdevices.

3.2. LED Indicators

RS232-Tx and RS232-Rx LED will flash accordingly when data is transmitted. For small data
transmissions, it may be hard to recognize the quick flashing action of the LED.

The values in box are the factory defaults. The flow control setting is configurable only through dip
switch.

3.4 Data Bit

Parani-SDsupports only 8 data bit. In the case of 7 data bit and even/oddparity, use SD 8 data bit and
none parity. At this time, master and slave are Parani-SD, Parani-ESD or Parani-MSP series. But 7
data bit and none parity is not support.

3.5 Hardware Flow Control

Parani-SD plugged into its host system transmits data from host to the other side Bluetooth device.
This data is saved temporarily in the internal buffer of Parani-SD and sent repeatedly until the
transmission is completed packet by packet. When the radio transmission condition is not good
enough to senddata promptly, it can cause a transmission delay. If the host sends more data when the
buffer is full, buffer overflow will make Parani-SD malfunction consequently. In order to prevent this
buffer overflow, Parani-SD works as follows.

When using hardware flow control, Parani-SD disables RTS so that it stops receiving any further data
from the host when the buffer becomes full. RTS will be re-enabled again to begin receiving data from
the host when the buffer has created more room for more data.

When hardware flow control is not being used, the Parani-SD clears the buffer to secure room for the
next data when the buffer becomes full. This can mean a loss of data may occur. As the transmission
data becomes large, the possibility of data loss becomes greater.

For large data transmissions, the use of hardware flowcontrol is highly recommended.

15

3.6 Reset to Factory Defaults

To set allthe configuration settings to its factory default parameters, press the reset button, depicted in
Fig. 1-3. Press and hold (for at least 1 sec) the reset button with a narrow pointed tool like paper clip.
Reset works only when power is on.

3.7 Dipswitch

With the combination of 4 slot dipswitches, baud rate and hardware flow control can be set.

Figure 3-1The Parani-SDDipswitch

Upper 3 dipswitches are used for setting the baud rate, and bottom dipswitch is used for setting
hardware flow control option. If the baud rate needs to a baud rate not shown below, ParaniWIN or
terminal program should be used to set these speeds. To set a baud rate not shown below the
dipswitches should be in the S/W Config setting. When in the S/W Config setting the baud rate will go
back to 9600 as default.

* Note: You cannot set the Parani-SD to a Baudrate of 1200 and 230K by way of the Dipswitch. If you
want to use them, to set these speeds, please configure the dipswitch to S/W Config setting and use
ParaniWIN or AT commands. Please refer to ParaniWIN and Appendix B.3.4
AT+UARTCONFIG,Baudrate,Paraty,Stopbit.

3.8 Pairing Button

Parani-SD provides Pairing Button for instant configuration without a PC to make an automatic
connection between two Parani-SDs. In this example we will refer to the two Parani-SDs as SD1 and
SD2, respectively. In pairing status,SD changes COD value automatically. (reference S43, S44)

Step 1. Turnon SD1 and SD2 and reset both of them by pressing Reset Button.
Step 2. Press the Pairing Button of SD1 for 2 seconds until Standby LED turns off and Connect LED

blinks 3 times every 2 seconds. Keep the power ON.

Step 3. Press the Pairing Button of SD2 for 2 seconds until Standby LED turns off and Connect LED

blinks 3 times every 2 seconds. Now press again the Pairing Button for 2 seconds until Connect
LED blinks every 0.5second.

Step 4. Wait for SD1 & SD2 to connect to each other until the Connect LED of SD1 and SD2 are fully

solid green. It takes about 10 seconds to make a connection. If there are many Bluetooth devices
nearby, it may take longer.

Step 5. TurnSD1 off and on. Connect LED blinks twice in green every 3 seconds.
Step 6. TurnSD2 off and on. Connect LED blinks once in green every 1 second.
Step 7. Now SD1 and SD2 are configured to make automatic connection to each other, whenever they

are powered on. Using a pair of Parani-SD in this fashion is similar to that of using a wireless serial
cable.

* Note: When using the pairing buttons, the Command Response option will be deactivated
automatically. The Parani-SD will not send the response messages such as OK, Connect and
Disconnect.

3.10 ParaniWIN

ParaniWIN is a program that runs on Microsoft Windows for the configuration of Parani-SD. Install
ParaniWIN on your computer. Plug a Parani-SD into the serial port of the computer and turn on the
power. Run ParaniWIN.

Figure 3-2Serial Port Setting

Set each option properly and click [Confirm]. If the settings of the Parani-SD are different from the
ParaniWin, an error message will pop up. If the Parani-SD is in the status of connection, warning
message will pop up. Then the current connection can be cancelled by [Disconnect] button on the
main window.

Serial port settings can be changed by <Start Configuration> and <ParaniWIN Configuration> of
ParaniWIN in the menu bar at upper left corner of the window without re-running the ParaniWIN
program.

Figure 3-5 Menu Bar at Upper Left corner of ParaniWIN

When the ParaniWin software is able to access the Parani-SD properly, the icons in the left side
window come will become available for use.

In device configuration window, hardware reset can be executed or operation mode and RS232 can
be configuredas well. Security option alsocan be configured in this window.

Figure 3-6 Device Setting Window

Parani-SD supports two security options, Authentication and Encryption. If you enable the
Authentication option, you must also enter a Pin Code value. If the authentication is enabled, the
connection, between the Master and Slave device must share the same Pin Code. In case that Parani-

20

SD connects to another Bluetooth device, that requires authentication, you must know the other
device’s Pin Code. In general, most Bluetooth devices have a pincode of 1234 or 0000. If you check
Encryption option, the Parani-SD will encrypt packets and sent to the device. The Encryption options
works well in case that only oneof the devices between Master and Slave use the Encryption option.

Parani-SD has 4 response messages, ‘OK’, ‘ERROR’, ‘CONNECT’, and ‘DISCONNECT’. In some
cases, these responses can affect the host system unexpectedly. To prevent this, user can set the
Commandresponse to ON or OFF.

For Parani-SD100/200, hardware flow control can be configured only by dip switch. And parity, stop bit
can be configured only SW config mode. Thus H/W Flow Control option will not work in this case.
When the dipswitch value isn’tATcommand mode, the Baud Rate menuwill be disabled.

Click [Apply] button to apply any changes made to the Parani-SD.
Connection(out) icon will show the following window to search and connect other Bluetooth devices.

Figure 3-7 Connection(out) Window

Click [Search] button to search nearby Bluetooth devices. Once several Bluetooth devices has been
found, select one of the devices and click the [Connect] button. The selectedBluetooth device must be
discoverable and connectable. Click [Disconnect] button to cancel the connection.

After the connection has been established, you will be able to test signal strength by pushing the
START button.

21

Figure 3-8 Signal Strength Test

The signal strength test shows LInkQuality and RSSI values. The closer LinkQuality is to 255 and
RSSI is to 0, this means the Parani-SD has a good connection to the connected Bluetooth device. In
general, the wireless connectivity is at its best within 10 meters. You can push the STOP button at
anytime in order to terminate the signal strength test. The signal strength test will continue until the
STOP button is pushed. If you close the ParaniWIN Window without pushing the STOP button, you
must restart Parani-SD to terminate the test.

Connection(in) icon will show the following window, which enables the Parani-SD to wait for a
connection fromanother Bluetooth device. If the waiting time is set to 0, Parani-SD will continually wait
for connection until [Cancel] button is clicked.

22

Figure 3-9 Connection(in) Window

If the ConnectionWizard icon is clicked, an easyto use pairing menu will appear:

23

In this example we will refer to the two Parani-SDs as SD1 and SD2 respectively. To use this menu,
please do the following:

Step 1. Connect SD1 and then push the START button.
Step 2. Disconnect SD1, connect SD2 and then push the Next button after setting up Slave

configuration. At this time, the dip switch value should be ATcmd mode. The flow control setting can
be changed only through dip switch.

Step 3. Disconnect SD2, once again connect SD1 and then push the Finish button. The pairing

configuration should be completed. Make sure that each Parani-SD’s connect LED is on. At this
point, when both Parani-SD’s restart the connection will be established automatically.

Appendix C: S-Register

S-registers contains 52 parameters for the Parani-SD Series. These are stored in flash memory and
the values will be saved unless hardware reset is executed. The value of S-register can be accessed
and changed with ATS command. Some S-registers not shown below are set to maximize the
performance of Parani-SD Series. Thus it is not recommended to change these S-registers.
Changing the values of S-register can only be done in the Standby mode. Turn Parani-SD off and on.

C.1. S1: Force to Reconnect (default 1)

S1=0, Parani-SD in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-SD in Mode1 keeps trying to reconnect when disconnected.

C.2. S3: Stream UART Policy (default 0)

S3=0, the priority of UARTstreaming is throughput.
S3=1, the priority is latency, which minimizes the delay of data transmission. This is useful in case of

transmitingvery small data quickly.
When this value is 1, in order to minimize latency, Parani-SD sends the received data immediately.
When this value is 0, the Parani-SD maximizes throughput, the Parani-SD stores received data for a
short time and sends a large data packet. If the packet length is less than 100 bytes, having latency
being the priority is recommended. If the packet length is more than 100 bytes, having throughput as
the priority is recommended. Also, if you want to use high baudrate, throughput priority will be more
effective. Just for reference, the buffer length for receivingdata is 2 Kbytes.

C.3. S4: Enable Remote Name Query (default 1)

S4=0, Parani-SD willquery only the BD address. This speeds up the inquiry process.
S4=1, Parani-SD willquery the BD address, device name and class of device.
When this value is 1, Parani-SD finds not only BD address but also friendly name. When this value is
0, Parani-SD finds only BD address. Whenset to 0 this will make queries much faster. When using the
pairing button, finding friendly name will be omitted automatically.

C.4. S6: Enable Low Power Mode (default 0)

S6=0, deactivate Low Power Mode.
S6=1, activate Low Power Mode.
This value decides whether Parani-SD works in Low Power Mode or not. When this value is 0, Parani­SD works only in active power mode. When Parani-SD works in Low Power mode, delay in
transferringdata may occur.

C.5. S10: Enable Response Message (default 1)

S10=0, Parani-SD does not send response messages to the host system.
S10=1, Parani-SD sends response messages to host system.
This value decides whether Parani-SD sends response messages such as OK, ERROR, CONNECT,
DISCONNECT or not. When this value is 0, Parani-SD will not send any response messages. If the
response messages conflicts with your host programs or devices that is connected to Parani-SD,
changethis value to 0.

C.6. S11: Enable Escape (default 1)

S11=0, Parani-SD does not allow escape sequence characters. The operation status of Connect

cannot be changed to Standby. Since the Parani-SD skips the process of detecting escape

sequence characters, more efficient data transmission can be had.
S11=1, Parani-SD allows for the escape sequence charactesr. Whenever it is needed, the Connect

status can be changed to Standby.

42

C.7. S12: Clear Data Buffer When Disconnected (default 0)

S12=0, Parani-SD does not clear the data buffer when disconnected.
S12=1, Parani-SD clears the data buffer when disconnected.

C.8. S13: Enable DCD Signal (default 1)

S13=0, DCD signaloff
S13=1, DCD signalon

C.9. S14: Enable DTR Transfer (default 1)

S14=0, DTR/DSRsignal is transferred in a loop-back fashion.
S14=1, DTR signal is transferred to DSR of remote device.

C.10. S15: Enable Disconnect by DTR (default 0)

S15=0, DTR signal cannot release the connection.
S15=1, The Bluetooth connection can be released when DTR signal is off.
This value decides whether Bluetooth connection is released when DTR signal drops or not. If this
value is 1, you can use DTR signalin order to disconnect Bluetooth connection.

C.11. S22: Faster Connection (default 0)

S22=0, none
S22=1, page scan
S22=2, inquiry scan
S22=3, page/inquiry scan

C.12. S23: Intercharacter Timeout Setting (default 0)

S23=0 : Not used
S23=1 : 1 x S26
S23=2 : 10 x S26
S23=3 : 100 x S26
Connecting time is average 1.5sec faster than normal mode.

C.13. S24: Maximum Number of Inquiry Result (default 10)

The maximum number of inquiry list can be controlled.This value is up to 15.

C.14. S26: Intercharacter Timeout (default 0)

S23=1 x S26=50 : Timeout-> 50msec
S23=2 x S26=50 : Timeout-> 500msec
S23=3 x S26=3 : Timeout-> 300msec

IntercharacterTimeout * Optimal Value(S23 x S26)
50ms 180
100ms 235
200ms 340

43

* When 10 bytes data are sent every intercharacter timeout, they are sent separately by 10 bytes at

the optimal value. If the intercharater timeout is set below the optimal value, the date will be put

together and sent by 20, 30, 40 bytes or more.

C.15. S28: Escape Sequence Character (default 43)

The decimal number of the ASCII code of escape sequence character can be controlled. The initial
value is 43, the ASCII code of ‘+’.

C.16. S31: Page Timeout (default 300)

This is the timeout in seconds to attempt connection with the ATD command. After this timeout expires,
the Parani-SD will restart automatically. If this value is 0, Parani-SD will attempt to connect without
restarting

C.17. S33: Inquiry Timeout (default 30)

This is the timeout in seconds to execute inquiry scan.

C.18. S37: Supervision Timeout (default 16000)

This is the timeout in 625μsec to presume disconnection, which is set to 16000 initially.
16000625μsec=10sec)
The smaller the value becomes, the more quickly Parani-SD can detect an abnormal disconnection.
But when the communication is suspended, it may be regardedas disconnection.

C.19. S43: COD (default 001F00)

This is the value of COD. Default value is 001F00(Uncategorized, specific device code not specified).

C.20. S44: COD Filter (default 000000)

This is the value ofinquiry COD filter.
Ex) ats44=001c00

C.21. S45: IAC(Inquiry access code)

The reserved IAC addresses are 0x9E8B00 ~ 0x9E8B3F. The general inquiry IAC is 0x9E8B33. So
default value is 0x9E8B33.

C.22. S46: BD Address of Last Connected Device

This saves the BD address of the Bluetooth device connected most recently.

C.23. S47: Select Low Power Mode (default 0)

S47=0, Select Park Mode
S47=1, Select Sniff Mode
When this value is 0, Parani-SD works only in park mode. When Parani-SD works in park mode, delay
in transferring data may occur. And if the value is 1, Parani-SD works in sniff mode. Parani-SD works
always low power mode but the data will be put together.

44

C.24. S48: Low Power Max Interval (default 2048)

This is the max interval value to use low power mode, which is set to 2048 initially. (2048 x 625μsec =
1280msec)

C.25. S49: Low Power Min Interval (default 800)

This is the min interval value to use low power mode, which is set to 800 initially. (800 x 625μsec =
500msec)
When sniff mode, a small sniff interval increases power consumption, a large sniff interval increases
latency. For low power modes, typical values of the sniff interval are from about 0.5 second to 1.28
seconds

C.26. S50: Low Power Sniff Attempt (default 8)

This is the sniff attempt value, which is set to 8 initially. (8 x 0.625μsec = 5msec)

C.27. S51: Low Power Sniff Timeout (default 8)

This is the sniff timeout value, which is set to 8 initially. (8 x 0.625μsec = 5msec)
The sniffing slave listens for traffic during the sniff slots determined by the sniff attempt parameter. If
no message addressed to the sniffing slave is received, the sniffing slave ceases listeningfor packets.
If a message with the sniffing slave’s active member address is received, it continues listening for
further sniff timeout slots after the sniff slot.

C.28. S52: Low Power Park Timeout (default 5)

This is the park timeout value, which is set to 5 initially. (5sec)
During no data transmission in park timeout, Parani-SD can be in low power mode to save the power.
It takes a few seconds to wake the Parani-SD out of low power mode.

Appendix D: Trouble Shooting

D.1. No Data Transmission

D.1.1. COM Port Settings

Check whether the Baud rate of Parani-SD matches that of its host equipment.
Check whether the host equipment has a Data bit setting of 8. Parani-SD supports only 8 Data bit
settings. If your host equipment uses 7 Data bit and even or odd parity, it may work with a 8 Data bit
and No parity setting. This is valid only when both DCE devices are the Parani-SD. In this case, set
both Parani-SDs to 8 Data bit and No parity. If one of DCE devices is another Bluetooth device such
as Bluetooth USB dongle,7 bit data configurations will not work.
Check whether the Parity and Stop bit of Parani-SD match those of your host equipment. Parani-SD
supports No parity, Even parity and Odd parity, 1 and 2 Stopbit configurations.
Check whether the host equipment of Parani-SD uses Hardware Flow Control. Parani-SD is initially
set to Use of Hardware Flow Control. If your host equipment does not use Hardware Flow Control,
please disable the Hardware flow control option by way of the dipswitch.
Parani-SD does not support RS-232 break signal.

D.1.2. Pin Assignment

Parani-SD is a DCE device. If your host equipment is DTE, plug Parani-SD directly to the host
equipment or use straight RS-232 cable. If your host equipment is DCE, use will need to use a cross
over RS-232 cable (Null modem cable) or a Male to Male DB9 Null Modem adapter.

D.2. Data Loss or Malfunctioning

D.2.1. Hardware Flow Control

When transmitting large amounts of data with No Hardware Flow Control, Parani-SD may clear the
data buffer unexpectedly. The possibility becomes greater as the RF transmission environment
becomes worse.

D.2.2. Response Message

AT response messages from the Parani-SD may affect the host system unexpectedly. Do not use
Parani-SD If your applications cannot allow for this wireless time delay.

D.3. Transmission Delay

D.3.1. RF Processing Delay

It takes 30msec approximately for a Parani-SD to complete a data transmission to the other Bluetooth
device. This time delay cannot be reduced and may enlarge as the RF transmission environment
becomes worse. Do not use Parani-SD If your applications cannot allow for this time delay.

D.3.2. RF Transmission Environment

If there are many Bluetooth devices working in a small area and/or the RF communication distance is
too great and/or there are some obstacles affecting RF performance, the Parani-SD repeats the
transmission packet by packet due to interferences and/or low RF performance. This may lead to
increased data transmission time delays.
