Hello Micheal and Tom,
I want to ask you, because I have a project that consist on sending real time data that change every 15 seconds over the Bluetooth module. I want to put the HC-05 in the data mode during 15 seconds, and then pass it to the AT command mode and lasts also for 15 seconds. I want to do that without restarting or disconnecting the power from my board (STM32). I already tried your solution to pass from the AT command mode to the data mode, by writing a C code (function that sends the command AT+RESET\r\n) and it works fine. But I want now the HC-05 turn back from the Data mode to the AT command mode. Any help please ?
