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.

Takes a 0x44-byte input struct, no output.
This is used by hid at some point when there's new hid connections, leaving "Change Grip/Order" in the Controller_Applet with new connections also triggers it via hid at some point.
Sends a request which is then handled as follows:
- Goes through multiple arrays of Address.
- First array:
- Validates the Address with state, skipping it if not found.
- Calls the SetTsi wrapper func described below, with the above Address and tsi=0xFF (Exit). If this returns false, CloseHidConnection is used with the Address.
- Second array:
- Validates the Address with state, skipping it if not found.
- Uses SetBleConnectionParameter with bool=true. Then the required EventInfo is loaded, {...}.
- Then it goes through the first array again, except here it does the following:
- Calls the same func for validating the Address with state, skipping it if not found. It is also skipped if the u32 at Address+0x8 is value 0x3.
- Determines what Tsi value to use, on failure CloseHidConnection is used and the loop is continued.
- Calls the SetTsi wrapper func described below, with the Address and the above Tsi value. If this returns false, CloseHidConnection is used with the Address.
- It then goes through various arrays again for updating state.
- {...}
- First array:
The SetTsi wrapper func is implemented as follows:
- Uses SetTsi, on failure true is returned.
- Gets the required EventInfo, returning false if a match wasn't found / EventInfo status indicates failure. True is returned for success.
Cmd62
Takes an input bool, no output.
Sends a request which is handled as follows: writes the flag into state if needed.
Cmd63
No input, returns an output bool.
This gets the flag used by #Cmd62.
Cmd64
