Pat Deegan takes a practical look at Bluetooth 6.0 channel sounding using Nordic’s nRF54L15 DK, breaking down how RTT, phase-based ranging, and the new sounding packets behave once you get them off the bench and into the real world. He digs into RF captures, decodes the packets, rewrites the sample code into a cleaner library, and runs open-air distance tests using reflectors, SDR tools, and his own analysis workflows. If you’re curious about how channel sounding actually performs, what the measurements look like at the signal level, or how to start experimenting with the 54-series devices, this deep dive offers a clear view of what’s possible today and where the challenges show up:
