I am trying to use a Microchip RN4871 BLE Module with my Arduino Micro. With the PC, using Tera Term, I can enter the command mode - pressing three times "$". Now I want to enter this mode with my arduino (to automate the configuration setup), but I cannot make it enter the command mode. I already tried to use Serial.write('$'), Serial.print("$") at no avail. Any help would be appreciated!
