Battery Power and UART0
Re: Battery Power and UART0
This might be related with the know hardware issue if Z-Wave chips - it changes MCU speed when connected to USB cable. Try a cable without data wires.

Thanks for your reply.
You mean i should try a power only usb cable? But if i use usb everything is fine... problem starts if i use a battery and no usb at all.

Make sure the UART speed matches
