Hi everyone,
I'd like to use the micro-esb radio interface to let to nRF's talk to each other. One of them will be generating 4 PWM outputs based on data received.
I have...

Hello,
We are doing a study about the features of nRF51822 and the nRF51 Development Kit and are wondering about the maximum visible "friendly name" (DEVICE_NAME?) which...
Greetings,
I am trying to get the frequency/channel matched with RSSI values using S110. Is there a way to pull it through the softdevice functions?
If not, can I pull...
I started with the beacon kit and example code. I have since added IAS and LLC services that I have mostly taken from your proximity example. The problem I am having now is...
