Appendix B: AT Commands B.1. Terminology B.1.1. AT Command AT command set is the de facto standard language for controlling modems. The AT command set was HT TH HT TH HT TH developed by Hayes and is recognized by virtually all personal computer modems. Parani-ESD HT TH HT TH provides the extended AT command set to control and configure the serial parameters and Bluetooth connection. B.1.1.
B.1.5. Symbols The symbols are used for the description of command syntax as follows: Symbols Meaning ASCII Code Carriage return 0x0D Line feed 0x0A Carriage return + Line feed Bluetooth device address N or m One digit decimal number to Timeout in seconds B.2.
B.3. Command Description B.3.1. ATZ SD Response OK Purpose Software Reset Description This is the same effect as power off and on. This command disconnects Bluetooth device, and stops ongoing task. After rebooting, the status is decided by the preset operation mode. Some AT commands need ATZ to take effect. Reference AT&F, AT+BTCSD, AT+UARTCONFIG B.3.2. AT&F SD Response OK Purpose Hardware reset Description This is the same effect as initialization by reset button.
B.3.5. AT+USEDIP? SD Response m Purpose Check the Baud rate set by dip switch Description m=0: Set to ‘AT cmd’ m=1: Set to other than ‘AT cmd’ Reference AT, ATZ, AT&F, ATS B.3.6. AT+BTINFO? SD Response 112233445566,DeviceName,Mode,Status,Auth,Encryp,FlowControl OK Purpose Display Bluetooth settings Description The current Bluetooth settings are displayed including BD address, Device name, Operation mode, Operation status, Authentication, Data Encryption, and Hardware Flow Control.

AT+BTRSSI,n SD Response OK 0,255,0,0 (repeatedly) Purpose Test sensitivity Parameters n=0: Start sensitivity test n=1: Stop sensitivity test Description When Bluetooth connection is established, you can use this command in Standby status.
Description In ‘Connect’ status, data from host is transmitted to the other side Bluetooth device, and any AT command is not accepted but this command, which is not echoed on the screen. When Parani-ESD encounters a character ‘+’ from host, it stops the data transmission and waits for next 2 characters. If the next 2 characters aren’t both ‘+’, it restart to transmit data including the first ‘+’ as well. If not, it converts the operation status to ‘Standby’.
This has the same effect as AT+BTSCAN,3,0. When connection is made with other Bluetooth device, SD response will be ‘CONNECT’ with its BD address. Reference ATD, AT+BTINQ?, AT+BTCANCEL B.3.17.
OK ERROR Purpose Connect to the last connected Bluetooth device Description Parani-ESD saves the BD address of the Bluetooth device most recently connected. ATD can make connection to it without input its BD address. If it fails to make connection, SD response is ‘ERROR’. Reference AT+BTINQ?, AT+BTSCAN B.3.20.
B.3.23. AT+BTSD? SD Response 112233445566 OK Purpose Display the list of Bluetooth devices sharing the pin code Description Once a connection is made with pin code, Parani-ESD saves the Bluetooth device with its link key generated by pin code. The connection to a device listed in Parani-ESD can be made automatically without authentication process. The maximum number of the list is 5. Reference AT+BTCSD, AT+BTFP, AT+BTKEY, AT+BTSEC, ATZ, AT&F B.3.24.
SD Response OK Purpose Change device name Parameters $string= New device name (Default=”PSDv3b-445566”) Description Parani-ESD can have a user friendly name to identify easily. The name allows 30 alphanumeric characters maximum. Reference AT+BTINFO?, AT+BTINQ? Example AT+BTNAME=”My-Parani-ESD” B.3.28.

Appendix C: S-Register S-registers contain 46 parameters of Parani-ESD. These are stored in flash memory and sustained the values unless hardware reset is executed. The value of S-register can be accessed and changed with ATS command by user. Some S-registers not shown below are set to maximize the performance of Parani-ESD. Thus it is not recommended to change these S-registers. Change the value of S-register only in Standby status. C.1.
C.5. S6: Enable Low Power Mode (default 0) S10=0, deactivate Low Power Mode. S10=1, activate Low Power Mode. This value decides whether SD works in Low Power Mode or not. When this value is 0, SD works only in active power mode. When SD works in Low Power mode, delay in transferring data may occur. C.6. S10: Enable SD Response (default 1) S10=0, Parani-ESD does not send SD responses to host system. S10=1, Parani-ESD send SD responses to host system.
C.12. S24: Maximum Number of Inquiry Result (default 10) The maximum number of inquiry list can be controlled. This value is up to 15, C.13. 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.14. S31: Page Timeout (default 300) This is the timeout in seconds to attempt connection with ATD command. After this timeout expires, the SD will restart automatically.
Appendix D: Trouble Shooting D.1 No Data Transmission D.1.1 COM Port Settings Check whether the Baud rate of Parani-ESD is same as that of its host equipment. If you don’t know the current Baud rate, initialize it to 9600 by resetting Check whether the Data bit is set to 8. Parani-ESD supports only 8 Data bit. If your host equipment uses 7 Data bit and even or odd parity, it can work as if it uses 8 Data bit and No parity. This is valid only when both DCE devices are Parani-ESD.
D.3 Transmission Delay D.3.1 RF Processing Delay It takes 30msec approximately for a Parani-ESD to complete the data transmission to the other side Bluetooth device. This time delay cannot be reduced and would be bigger as the RF transmission environment is bad. Do not use Parani-ESD If your applications cannot allow this time delay. D.3.
