Almost all Bluetooth products have MCU'에스, but How To Make Communication Between the MCU 그리고 블루투스 모듈? Today you would learn about how.

Taking the BT906 as an example:

1.연결하다 MCU 그리고 블루투스 모듈 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)열려 있는 ”피지컴 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 피지컴 
3)Open txt file to select the cursor
4)Send hexadecimal
             
 41 54 2B 48 49 44 53 45 4E 44 3디 32 2기음 00 04 0D 0A. Then cellphone will received:  a
A T + H I D S E N D = 2 ,       \r \n
                                00: ”control key” value
                                04: ”hid value” ~의 ” a ”
