I use Arduino Primo Core with the NRF Library Version 1.0.2
Here some of the Bugs I found:
BLE RADIO is always active, even when you dont want to use BLE functions.
It is not possible to deactivate BLE RADIO to reduce power consumption
sleep() Current consumtion > 2mA
( deepsleep() is no option for me
sleep() mode is not working when you use function tone() once
(and later of course noTone() to disable PWM )
sleep() Current consumtion > 5mA
sleep() mode is nor working when you use function analogRead() once
programm crashed
In detail:
first I use Pin 2 as a Digital output,
then i switch the pin to a Digital input and use analogRead(2)
then the program crashes when I enter the sleep() mode
I now changed the wiring and use Pin 2 only with analogRead(2)
This workaround helped
