Can someone please post example how can I measure battery with 022001-0 module. I have the same code working for 012011-0.
When I change the Vref to pin 1.7 and use one of pins 3.X as ADC inputs, the battery measurement does not work.
Solved! Go to Solution.

Hello Uros,
For CYBLE-022001-00 module, the VREF pin has bypass capacitor as shown in below schematic diagram which was not externally connected to pad. So It is not possible to connect the analog input pin to the VREF for battery measurement.
For CYBLE-012011-00 module, the VREF pin is externally connected to the pad as shown in below image. So we can connect the input of SAR ADC to this VREF pin for battery measurement.
Thanks,
P Yugandhar.
