Hello, I have the same issue, Hola a todos!. I trie, 4 AAA 1.5v, One 9 V Battery and USB Battery (no PC plug, a portable charger). After that, i tried a voltage divisor on RX on Bluetooth Module HC, same problem, any one can help me pls =( Regards.

Maxi Ber the problem relies in the power source

Really, thanks for the response, Gracias Camilo. Wht source should i Use? I tried 4 AA 1.5, Power Bank USB, and 9v Battery. When I send a move action from the app, the bluetooh disconect. Thanks!

Maxi Ber 9V battery has to be a Lithium rechargeable one that provides at least 650mA, if is a regular alkaline it wont work.
