Testing with NCS 3.0.1 and nRF54L15-DK. I would like my devices to be able to work as channel sounding initiator as well as reflector role. In my own code I have integrated the code from samples channel_sounding_ras_initiator and channel_sounding_ras_reflector, and that works so far. However, when I enable CONFIG_BT_RAS_RREQ=y and CONFIG_BT_RAS_RRSP=y at the same time, even with CONFIG_BT_RAS_RRSP_AUTO_ALLOC_INSTANCE=n then I fail to get results on the initiator side (the reflector side works fine). I always get the error "Tried to parse empty step data".
You can easily reproduce this by adding
CONFIG_BT_RAS_RRSP=y
CONFIG_BT_RAS_RRSP_AUTO_ALLOC_INSTANCE=n
to channel_sounding_ras_initiator.
