Hello guys, i have some problems with my Hc-05 and with my android phone. Im making a simple ON/OFF led control with my arduino.
I can pair my device with hc-05 module but when i try to connect it being in the android app (on app inventor) it doesn't work. Here is the code in the app inventor:
When i press the list picker appears this: Error 503: The specified adress is not a valid Bluetooth MAC adress.
Hope you'll help me, Thank youu
