BTM services
btm
This is "nn::btm::IBtm".
Support for "nn::btm::*" was added to sdknso with 6.x.
This has max_sessions 6. IPC is handled by 2 threads shared with all services.
These btm services with BLE only allow connecting to devices which have a #GattService with a certain custom UUID present.
The output bool from all of these btm* service get-event cmds indicates whether the Event was successfully returned, user-processes will Abort when this is 0.
