How can you get the simple channel sounding test going with the bluetooth/cs shell commands?
I've got the shell working over UART and devices talking with each other but can never get passed:
Received subevent results.
Subevent Header:
- Procedure Counter: 0
- Frequency Compensation: 0x0000
- Reference Power Level: -61
- Procedure Done Status: 0x00

This is aborting for reason 0x02, i.e. BT_HCI_LE_CS_PROCEDURE_ABORT_REASON_TOO_FEW_CHANNELS. I've tried messing with the internals to get more channels enabled than the default to wind up with a config something like this:
- ID: 0
- Role: Initiator
- Main mode: 2 (PBR)
- Sub mode: 1 (RTT)
- RTT type: AA only
- Main mode steps: 2 - 3
- Main mode repetition: 3
- Mode 0 steps: 3
- CS sync PHY: LE 1M PHY
- T_IP1 time: 60
- T_IP2 time: 30
- T_FCS time: 80
- T_PM time: 20
- Channel map: 0x1FFFFFFFFFFFFC7FFFFC
- Channel map repetition: 3
- Channel selection type: Algorithm #3b
- Ch3c shape: Hat shape
- Ch3c jump: 2
but it just never works. Perhaps I'm missing something with the sequence of shell commands--the commands are all there, but there aren't any examples of actually using anything. So I've worked out the following sequence:
bt init
bt connect-name MY_REFLECTOR
bt security 2
cs read_remote_supported_capabilities
cs set_default_settings true false 0x01 -20
cs security_enable
cs default_config initiator local-remote
cs create_config 0 local-only initiator pbr-rtt aa-only
cs set_procedure_parameters
cs start_simple_cs_test 0
Has anyone got the CS start_simple_cs_test actually working and can you specify how you managed to do so/anything you see in the above I'm doing wrong.
Thanks,
