My application works great on it using the SoftDevice S130 as BLE stack....
Hello!
I have been experiencing some trouble with the PStorage API. I have browsed every example and similar question I can find and none seem to match the continuing issues...
Now, we are checking nRF51822 ADC sample program in SDK.
When P0.1 input is lower than 0.7V, outputs is 0.
We are wondering if the performance is correct.
Could you...
I've been going back and forth with my manager, and I need source to show whether I'm right or wrong about a specific possible functionality of the nRF51.
I was wondering...
