Hello
I bought this arm:
https://www.amazon.ae/dp/B0BV9ZC ... ct_details&th=1
And also bought this Bluetooth Module:
https://www.amazon.ae/dp/B071YJG ... t_b_product_details



This is the board:
https://www.adeept.com/u_file/2305/photo/6f5f7a2510.jpg


I cannot send or receive commands,

SoftwareSerial mySerial(10, 11); // RX, TX
For (RX, TX) I tried:
(0, 1)
(2, 3)
(10, 11)
(16, 17)
(30, 31)


but did not get "ok" for the command "AT" ever

Also I tried:
mySerial.begin(9600);
and tried:
mySerial.begin(38400);

Do you have any sample how this Bluetooth part can work?


Thanks,

You can judge the current status of the Bluetooth module based on the LED indicator light on the Bluetooth module. Take the HC-05 Bluetooth as an example.
LED flashes quickly: No Bluetooth device is connected.
LED flashes slowly (flash once every 2 seconds): Enter AT command mode.
Please confirm whether the Bluetooth device successfully enters AT command mode.
