Bluetooth Driver services

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.

btdrv appears to be designed to only be used by the two sysmodules which use it, hid and btm. This service uses global state, nothing service-session-specific.

This has max_sessions 30. IPC handling is done by the main-thread.

Takes a type-0x16 output buffer containing a #ChannelMapList.

bt

This is "nn::bluetooth::IBluetoothUser".

This has max_sessions 30. IPC handling is done by the main-thread.

LeSendIndication

Takes a PID, a type-0x9 input buffer, an u8, a bool, a #GattAttributeUuid, a #GattAttributeUuid, an AppletResourceUserId, no output.

The AppletResourceUserId is unused.

The buffer size used internally is clamped to max size 0x258.

GetLeEventInfo

Takes a PID, a type-0xA output buffer, an AppletResourceUserId, returns an output #BleEventType.

This is identical to #GetLeHidEventInfo except different state is used. The AppletResourceUserId is unused.

RegisterBleEvent

Takes a PID, an AppletResourceUserId, returns an output Event handle with EventClearMode=1.

This is identical to #RegisterBleHidEvent except different Event state is used. The AppletResourceUserId is unused.
