Powering loraone from battery

We are a little bit confused about the hardware setup for connecting a battery to the lora one. It only appears to work when the external interrupt pin is connected to a power pin. Is this the normal setup?
Also, how do you properly connect a solar panel?


In order to power up the SodaqONE from a non USB power source, you must apply a voltage to the EXTERNAL_SWITCH pin.

You can either keep that pin HIGH or alternatively you should set ENABLE_PIN_IO HIGH at the start of your sketch:

digitalWrite(ENABLE_PIN_IO, HIGH);

This will allow you to attach a switch or a button to the EXTERNAL_SWITCH pin to activate the device.
