Okay, my bad. I did not read properly the documentation where it states that AccessorySetupKit is required for ChannelSounding to work. This is fine, I don't mind going through that extra step. Unfortunately AccessorySetupKit is not compatible with a Bluetooth LE - scanner type app since it wants exclusive CBCentralManager access, and also, it will stop CBCentralManager from returning unpaired devices... :(

Hello, when you built the sample firmware for your nRF54L15DK, did you enable bonding in the ipt_reflector sample? This requires both a change in the prj.conf file as well as some minor modifications in the main.c file. Feel free to each out via Nordic DevZone for help.

Can confirm it now works. Tested with Nordic nRF54L15's ipt_reflector sample, modified to add RAS (Ranging Service) in Advertisement Data + Enabling Bonding. Can you confirm Bonding is required for Channel Sounding to work? It was tricky on my end to figure that one out. Thanks for addressing the issue so quickly.
