Hi,
I have a simple question about Bluetooth Channel Sounding:
Question: If I use BT_CONN_LE_CS_MAIN_MODE_3
as main mode (PBR + RTT), does it make sense to use sub mode like BT_CONN_LE_CS_SUB_MODE_2
(or any except BT_CONN_LE_CS_SUB_MODE_UNUSED
)? How does this all work?
My setup:
.main_mode_type = BT_CONN_LE_CS_MAIN_MODE_3, // PBR + RTT
.sub_mode_type = BT_CONN_LE_CS_SUB_MODE_2, // RTT only
.min_main_mode_steps = 2,
.max_main_mode_steps = 5,
What I think it does:
- Main mode = most T_FCS steps use Mode 3
- Sub mode = sometimes use Mode 2 between main mode steps
- "Sometimes" means: do 2-5 main steps, then 1 sub step, then repeat?
Questions:
- Do I understand this correctly?
- How does the CS system know when to use sub mode?
Thank you.
