Today when I started power profiler kit, it suddenly started to show peak values like 80 mA. This has not happened before, but the values with the same hardware have been...
In the data sheet of the NRF51 and 52 there is mention that sensitivity of NRF51 is -96 dBm and NRF52 -98.
But I read some where that when RSSI is -90 then that signal...
We are working on a dynamic radio power change for a proprietary RF protocol, and we are missing some granularity on the NRF_RADIO->POWER levels.
Typically we would need...
I am wondering what is the logic and magic behind using sdk API's to advertise vendor specific 128-bit service UUIDs. In the "Nordic UART Service" example (nus, SDK12.2.0...
