7. Typical Application The f ollowing sc hematic i s the ty pical hardw are a pplication for the BTM- 5 module, it provide both RS232 and 5V TTL logic level connection to the module.
We prov ide t wo variations of BTM-5 breakout board, one is RS23 2 interface, the ot her is TTL interface. Note that t hese two dif ferent br eakout bo ard use different su pply v oltage an d different interface, please take care before using them.

User can change the default setting of BTM-5 module with the AT command via onboard button or ‘Mode’ pin. If t he bottom pressed or ‘Mode’ pin pulled high, the module enter the AT command mode. The breakout board provide two LED to i ndicate the status of t he module, the RED led indicate the link activity status, the GREEN led indicate the pairing status.

8. Basic AT Command Users can use AT commands to s etup the m odule with dif ferent configurations. Every AT command must be fol lowed with < CR> and
control character w hich is 0x0D and 0 x0A i n hexadecimal. Every AT command will foll owed with a response "OK". They will be som e basic AT command you should know. 1.
AT
AT command is use to test the module to see if it is OK. 2.
AT+RESET
AT+RESET command is reset the module back to power up status. 3.
AT+ROLE?
AT+ROLE? command inquiry the module's role, 0 = Slave, 1 = Master, 2 = Slave-loopback. 4.
AT+ROLE=
AT+ROLE command is used to set the module with master or slave, 0 = Slave, 1 = Master, 2 = Slave-loopback. You have to configure one module to master and the other to slave to become a pair. 5.
AT+CMODE?
AT+CMODE? command inquiry the link mode. 0 = Specific bluetooth link address, 1 = Any bluetooth link address, 2 = Slave-loopback 6.
AT+CMODE=
AT+CMODE com mand is use d to set up m odule l ink m ode. 0 = Spec ific b luetooth link address, 1 = Any bluetooth link address, 2 = Slave-loopback. It is better to set the mode to 1 if you only have one pair device, because it is much easier to make them a pair. 7.
AT+PSWD?
AT+PSWD? command inquiry the password of the module. 8.
AT+PSWD=
AT+PSWD command is used to set the pairing password. 9.
AT+UART?
AT+UART? command inquiry the uart configurations

Schematic overview The following schematic is the typical hardware app lication for the BTM-5 module, it provide both RS232 and 5V TTL logic level connection to the module.
The BTM-5 module pairs is default configured with 115200bps baud rate, the master and slave's PIO8 (Pin31) indicate the link status which is connected to a LED (D2) shown in the application schematic. When power up, the both module's LED flashes every 0.5 seconds and look for each other for pairing. After successfully pairing, the LED flashes 3 seconds. At this time you can transmit data via the UART port with each other. The module's PIO11 (Pin32) is a mode selection pin to switch between normal mode and AT command mode. In the application schematic, it is connected to a button S1. When it is press down the module enter AT command mode, it come back to normal mode if the button is released. Note that, when the link is not established, once the module enter AT command mode, it will not come back to normal mode until link established or send a AT+RESET command or re-power the module.
FAQ and Known Issues •

The module is delivered with a default baud rate of 115200, although 38400baud is specified in the document. After sending AT+RESET, the module restores some "factory defaults" and the baud rate changes to 38400 Changing the PIO11 level from 0 to 1 or vice-versa, when the module is powered, changes the mode of operation istantly but the LED on PIO8 blinks the same way. Thus the user does not know whether the module changed the operation mode or not. The only way to find out is trying to send AT commands and see if it responds in any way. When the module is powered up in Data Transfer Mode, the LED blinks quickly (2-3Hz) indicating that the module is ready to connect. After a connection has been established the LED on PIO9 lights up and the LED on PIO8 blinks short twice every second. When the module is powered up in AT Command Mode, the LED on PIO8 blinks slowly(1 Hz). REGARDLESS of PIO11 level (0 or 1) changing the BT Connection state switches the module into Data Transfer Mode. If PIO11 is 1 and the user wants to continue with the AT Command Mode after a BT connection has been establishes it has to toggle PIO11 to switch the module back in AT Command mode.
