Almost all Bluetooth products have مکشبه’s, but How To Make Communication Between the مکشبه و ماژول بلوتوث? Today you would learn about how.

Taking the BT906 as an example:

1.Connect the مکشبه و ماژول بلوتوث properly.
Usually you may know that just need use UART (TX /RX) then can communicated .
Your MCU TX connected to BT906 module’s RX.Please checked if you already do like this ?
If you have confirmed that there are no circuit problems,then we go to step 2

2. Make sure the Hardware Part is okay.
1)Connect the TX RX of the module to the computer through the 3.3V USB Transfer to Serial Port
2)Open ”بد بو Serial Port ”,choose the related port ,Baurd Rate :115200 ,Choose :New Line
3) Send ”AT+VER ” ,If there is a respond :+VER=xxxxx,then it means hardware it is okay .

3.Make sure the software part is okay.
1)Send ”AT+MODE=2 ,then it will change into hid mode
2)Use cellphone connected to hid device named بد بو 
3)Open txt file to select the cursor
4)Send hexadecimal

A T + H I D S E N D = 2 ,       \r \n
                                00: ”control key” value
                                04: ”hid value” از ” بوها ”
