I have a 32 bit board with an HC-05 device to be used as a bluetooth port downloades yesterday last very last android APP if I pair the phone with the HC-05 it works and the flashing led change state (from fast to slow blinking) if i try to do this with the app i see the tick close to the device in the butooth label but nothing work, and i can't do anything as they are not paired any suggestion? thank you in advance
i have done all the test i have bought an USB to Serial interface, and connected with a terminal AT commands works without problems set speed with AT+UART=115200,1,0 or AT+UART=115200,1,1
but no changes if I pair with the phone, it works and led change status
as fast as I launch the SimpleBGC android APP led starts again to flash faster and no way to connect
