Are these SoC devices often used to act as serial-over-BLE bridges? I have a barbecue controller from ThermoWorks that I have been trying to reverse engineer.

Are these SoC devices often used to act as serial-over-BLE bridges? I have a barbecue controller from ThermoWorks that I have been trying to reverse engineer. Sniffing BLE has been pretty useless for this thing because it appears to be using BLE as a mechanism to do basic serial comms. I would like to understand more how these serial implementations work and to find some resources that I could use to capture the protocol.
