btdrv
This is "nn::bluetooth::IBluetoothDriver".
The bluetooth driver implements the bluetooth protocol over h4/uart.
It interfaces with the uart service to actually talk with the bluetooth hardware.
The code seems to be derived from a broadcom stack. A good starting point for similar source code can be found in the MICO project: https://github.com/yinhongxing/mico/tree/ea67ff3659f12d730d4dc3b8d547b093bd2ee2ee/MICO/bluetooth_bte Note that the library files contain many (symbolized) functions which match btdrv.
Support for "nn::bluetooth::*" was added to sdknso with 6.x.
This has max_sessions 30.
Various cmdids were moved with [4.0.0+] and [5.0.0+].
InitializeBluetoothDriver
No input/output.
This is the first cmd used during service init.
This just returns 0.
InitializeBluetooth
No input, returns an output Event handle with EventClearMode=1.
This is used by btm, this should not be used by other processes.
EnableBluetooth
No input/output.
DisableBluetooth
No input/output.
FinalizeBluetooth
No input/output.
Not used by btm, other processes should not use this.
GetAdapterProperties
Takes a type-0x1A output buffer containing an #AdapterProperty.
GetAdapterProperty
Takes an input #BluetoothPropertyType and a type-0xA output buffer.
SetAdapterProperty
Takes an input #BluetoothPropertyType and a type-0x9 input buffer.
StartInquiry
No input/output.
StopInquiry
No input/output.
CreateBond
Takes an input #Address and a type-0x19 input buffer containing a #TransportType, no output.
[9.0.0+] Now only takes an #Address and a #TransportType without a buffer, no output.
RemoveBond
Takes an input #Address, no output.
CancelBond
Takes an input #Address, no output.
RespondToPinRequest
Takes an input #Address, a bool, an u8, a #BluetoothPinCode, no output.
sdknso uses an user-specified s32 for the u8.

Takes an input #Address, a #BluetoothSspVariant, a bool, an u32, no output.
GetEventInfo
Takes a type-0xA output buffer and returns an output #EventType.
InitializeHid
Takes an input u16, returns an output Event with EventClearMode=1.
Originally sdknso used an user-specified value for the u16, however with [9.0.0+] it uses hard-coded value 0x1 instead.
This is used by btm, this should not be used by other processes.

No input, takes a type-0xA output buffer and returns a #HidEventType.
[7.0.0+] No longer takes a buffer or returns output, now returns an output sharedmem handle. sdknso maps this with size=0x3000 and permissions=RW-.
Originally this was used in a dedicated sdknso func, with [7.0.0+] this is now used at the start of the sdknso impl for #RegisterHidReportEvent if the above sharedmem was not mapped yet.
The [7.0.0+] GetHidReportEventInfo sdknso func loads data using the above sharedmem.
