I suppose I’d see “OK” in the terminal environment which is opened
but i just see “AT” because I send it to the serial terminal in setup part of the program. since led blinks 1sec on and 1sec off, I know I am not in at command mode.
I set baudrate equal to 9600 too.
here is my code
SoftwareSerial BTserial(2, 3); // RX | TX
// Connect the HC-08 TX to Arduino pin 2 RX.
// Connect the HC-08 RX to Arduino pin 3 TX through a voltage divider.
