Communication Mode

Utilizes a pairing mechanism that allows reliable 1:1 communication.

1:1 Communication

• When using two BT-210s, it is possible to set one as the “Master” and the other as the “Slave” use the device to communicate with each other. Also, It is possible to use the BT-210 with a smart phone—with the Bluetooth capability—by setting BT-210 to “Slave mode” and pairing the two devices to each other.
• When the power is initially supplied to the BT-210, the blue LED blinks. Once the pairing is successful the blinking stops and the blue LED light is maintained.

BT-210 Setting

Setup

1. Download example “c_Serial_Serial2_Converter” from Arduino or f_SerialUSB_Serial2_Converter” from OpenCM IDE for the OpenCM-9.04.

   With references to add “OpenCM9.04” Board Manager to Arduino IDE

   

   When using Arduino IDE

   

   WARNING : OpenCM IDE is not updated anymore. It is recommanded to use Arduino IDE as OpenCM IDE isn’t maintanined anymore.

   When using OpenCM IDE

2. Connect the BT-210 to the OpenCM9.04, then run Tera Term.

   • Download Tera Term

   

   

3. Once connection is complete baud rate can be any.

   

4. Go to Setup->Terminal and check local echo.

   

5. Enter ! in terminal and if OK is returned, BT-210 is in Command Mode. Enter AT and if OK is returned, now BT-210 is ready for the setting.

   

6. Once setup is completed, reconnect the BT-210 with the controller. The picture shows BT-210 is set as a Master.

   

AT Commands

The following are AT terminal commands for the BT-210

NOTE:
If an error comes in the cmd, input ”!”(Shift+1) to restart writing.
If the command fails or does’t move to the next step, input “AT(at)” or ”!”, then re-input.
If the BT module is not detected, then the controller or firmware needs to be restored.

1. System reset Enter ATZ press the Enter key and the BT-210 resets.if settings have changed the mode will change upon reset.

   

2. Mode change
   • Use this command to switch between master and slave modes for the BT-210.
     • AT+BTROLE=M -> Master mode
     • AT+BTROLE=S -> Slave mode
   • Afterwards enter ATZ to reset.

   

   MASTER Mode

   

   SLAVE Mode

3. Peripheral device search This is possible only in master mode. Enter AT+BTINQ followed by the Enter key the device class comes as 0x1F00(SPP).

   

4. Connecting devices (pairing) Once devices have been found they can be connected via its 12-digit hex MAC address. for example a device with MAC address of abc2-ff-123458 enter ATDabc2ff123458 (ignore the – sign). When asked for pin code enter 0000.

   

5. Change pin code
   • AT+BTKEY=digit Pin Code
   • To change pin code follow the procedure below.

   

   • then enter AT+BTKEY (ignore the = sign)

   

6. Output current device class Output of SPP (serial port profile) 0x1f00

   

7. Change Bluetooth device name AT+BTNAME = for name change

   

8. Device Under Test (DUT) mode Under this mode the device is a “test” device and not suited for applications.

   

   Enter AT+BTDUT then ATZ (make sure is in slave mode) To get out of DUT mode enter AT+BTDUT one more time then ATZ

9. Change Baudrate AT+BTUART,baudrate,parity_bit,stop_bit Example AT+BTUART,57600,n,1
