I have a bit of a strange problem.
I am designing a signal Gazell signal repeater.
It listens in host mode then sets itself as a device to pass the data along.
However...
Is it possible to put the nRF52 into recieve only mode (say through direct test mode) so that the input impedance can be measured using a VNA? Is the input impedance of the...
When I initialize PPI after timer1 has been initialized I get a fatal error (and reset).
Code:

Hello,
we were measuring sleep modes and it consumes around 1.3uA which is correct.
But when we needed to be woken up on edge we found out it consumes extra 8uA! Are you...
Are there any nRF51 demo firmware implementing paring function that the central and peripheral devices will connect automatically without user interaction when they come ...
