Please see image below from a spectrum analyser.
It is the received signal from 2 units both transmitting a constant...
Hi, I would like to analyze data between a peripheral and a central (BLE 4.1.) It seems that the nRF52 and sniffer can only monitor advertising channels. Am I missing something...
Hello,
I have designed a PCB (25mmx55mm) and placed the nRF24l01 module (available as a standard add on module). But I am unable to get the data out of the board. I have...
Hi Nordic,
Are there any plans to update the BLE Sniffer?
It would be great if all the op codes for logical link control could be added and to fix the malformed packets...
This is the Energy Profile that is shown for the nRF82832 and I am wondering about the RX/ switch parts. I assume these RX phases are for receiving scan requests?
What happens...
Hi,
I have a question regarding DTM in nRF5 SDK v14.2.0.
