Using the battery as main power supply (Sara AFF R410M)

Good afternoon,

I would like to use a battery as main power supply, in stead of USB.
When I connect the battery to the battery pins (Vin & Ground), I measure a voltage of 3.7.
Unfortunately the program doesn’t seem to start.
Do I have to set another pin in the software?

Kind regards,


Never mind, resetting the board while only having the battery connected did the trick.
