Dear TI Engineer,

We have some question about the CC3301 and CC3351, did them support the BT5.3 Channel Sounding function? One of our new project have the WiFi and BLE wireless connecivity demand, BLE is used for positioning, with an accuracy requirement of 0.5m. It seems that the CC3301 and CC3351 can meet our requirement.

Thanks,

Kind Regards
