a rf32 user guide ref. 08-07-v10-ltu p 6 overview the a rf32 module enables bluetooth ? compliant duplex communications over a 20-meter range in the worldwide 2.45 ghz frequency band. the a rf32 module fully complies with the v2.0 bluetooth ? standard and data rate goes up to 723 kbps. data exchange and set-up are only done through an uart data port, under spp profile. a miniature antenna is integrated. a rf32 can be used in two modes: classical bluetooth? mode : master starts with gap identification, then, sdap profile review, s pp connection and transparent communication.
a rf32 user guide ref. 08-07-v10-ltu p 7 automatic bluetooth? mode: identification, profile review and connection to 1 to 3 known slaves are recorded by the master. after booting, bluetooth ? link is directly open in transparent mode. a rf32 modules are available as standa lone arf7044 module or in the arf7069 demokit. this demokit can be fully set-up and used with the national semiconductors ? ?simply blue commander? software. hardware essentials pin-out all connections are located on the a rf32 bottom connector: inte g rated antenna 32 khz xtal ? data rate ? jumper bluetooth ? chi p bottom connector main xtal eeprom

a rf32 user guide ref. 08-07-v10-ltu p 13 operating modes there are two main operating modes in the module : command mode and transparent mode. the command mode is used to set up the bluetooth ? link between two pieces of bluetooth ? equipment. the transparent mode is used to tr ansfer data between two pieces of bluetooth ? equipment. command mode a specific protocol is used to send commands to the bluetooth ? module. the frame format is the following : all the values are in hexadecimal format. start delimiter packet type operation code data length check- sum data end delimiter 1 byte 1 byte 1 byte 2 bytes 1 byte bytes 1 byte start delimiter: 02 () packet type : 52 (?r? for request), 69 (?i? for indication), 43 (?c? for confirm) operation code : command dependent data length : size of data. first byte is the least significant byte and second byte is the most significant byte checksum: sum of all bytes from the packet type field to the data length field data : command data end delimite r: 03 () example of the inquiry command start delimiter packet type operation code data length check- sum data end delimiter 02 52 00 03 00 55 0a 00 00 03 frame : 02 52 00 03 00 55 0a 00 00 03

a rf32 user guide ref. 08-07-v10-ltu p 15 final use with a pc terminal or a microcontroller power up the two bluetooth ? modules. connect one module with the rs232 link to a pc or notebook or pda. use a terminal software configured at the current baudrate (9600 by default), 8 bits, 1 stop, no parity, flow control material. please find below a typical request / response sequence in order to establish a typical link. all requests must be sending by the pc / nb / pda (i.e. the master). all indication and confirm responses are sent by the bluetooth ? slave module: > giac inquiry request: 02 52 00 03 00 55 0a 00 00 03 < inquiry module indication: 02 69 01 09 00 73 34 be 1f 17 00 08 00 00 00 03 in bold : address of the target bluetooth ? module. this address will be used within the command sdap connect and the command spp connect < inquiry module confirm: 02 43 00 01 00 44 00 03 > sdap connect request: 02 52 32 06 00 8a 34 be 1f 17 00 08 03 < sdap connect module confirm: 02 43 32 01 00 76 00 03 > sdap service browse spp request: 02 52 35 02 00 89 01 11 03 < sdap service browse spp module confirm: 02 43 35 0d 00 85 00 01 02 10 01 11 01 05 43 4f 4d 31 00 03 > sdap disconnect request: 02 52 33 00 00 85 03 < sdap disconnect module confirm: 02 43 33 01 00 77 00 03 > spp connect request: 02 52 0a 08 00 64 01 34 be 1f 17 00 08 01 03 < spp connect module confirm: 02 43 0a 02 00 4f 00 01 03 < spp connect module indication: 02 69 3e 04 00 ab 01 0c 00 00 03 > enter transparent mode: 02 52 11 01 00 64 01 03 < enter transparent mode module confirm: 02 43 11 02 00 56 00 01 03 now you can exchange data in transparent mode between the two bluetooth ? modules. to come back to the command mode you have to send an uart break.
a rf32 user guide ref. 08-07-v10-ltu p 16 automatic connection for serial cable replacement the a rf32 master can be configured to connect automatically to a specific a rf32 slave and switch to transparent mode. the automatic connection is done on boot or reset. the a rf32 master tries 3 times the link establishment. in order to do this the following commands have to be entered one time on the a rf32 master with for example the ?s imply blue commander software: > store default connection request : 02 52 13 0a 00 6f 01 01 01 34 be 1f 17 00 08 01 03 < store default connection confirm 02 43 13 01 00 57 00 03 in bold : address of the target bluetooth module. > write operation mode (auto) request : 02 52 4a 01 00 9d 01 03 < write operation mode confirm 02 43 4a 01 00 8e 00 03 advanced commands other commands are available in command mode. please refer to the national semiconductors ?simply blue commander software and ?software user guide?
