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.

No input, returns an output #IBtmUserCore.
IBtmUserCore
This is "nn::btm::IBtmUserCore".
AcquireBleScanEvent
No input, returns an output u8 and an Event handle with EventClearMode=1.
sdknso will Abort if the output u8 is value 0.
GetBleScanFilterParameter
Takes an input u16, returns a BleAdvertisePacketParameter.
The u16 must be value 0x1 or 0xFFFF.
GetBleScanFilterParameter2
Takes an input u16, returns a GattAttributeUuid.
The u16 must be value 0x2. The first 4-bytes of output is always 0 since it's not set.
StartBleScanForGeneral
Takes a PID, a BleAdvertisePacketParameter, an AppletResourceUserId, no output.
StopBleScanForGeneral
No input/output.
GetBleScanResultsForGeneral
Takes a PID, a type-0x6 output buffer containing an array of BleScanResult, an AppletResourceUserId, returns an output u8 total_out.
The max array entries is 10.
StartBleScanForPaired
Takes a PID, a BleAdvertisePacketParameter, an AppletResourceUserId, no output.
StopBleScanForPaired
No input/output.
StartBleScanForSmartDevice
Takes a PID, a GattAttributeUuid, an AppletResourceUserId, no output.
StopBleScanForSmartDevice
No input/output.
GetBleScanResultsForSmartDevice
Takes a PID, a type-0x6 output buffer containing an array of BleScanResult, an AppletResourceUserId, returns an output u8 total_out.
The max array entries is 10.
AcquireBleConnectionEvent
No input, returns an output u8 and an Event handle with EventClearMode=1.
sdknso will Abort if the output u8 is value 0.
BleConnect
Takes a PID, an Address, an AppletResourceUserId, no output.
An error is thrown if the Address is already connected (listed in the BleConnectionInfo from #BleGetConnectionState). An error is thrown if 4 devices are already connected.
BleDisconnect
Takes an input u32, no output.
The u32 must match an Id in a BleConnectionInfo from #BleGetConnectionState (0xFFFFFFFF is invalid).
BleGetConnectionState
Takes a PID, a type-0xA output buffer containing an array of BleConnectionInfo, an AppletResourceUserId, returns an output u8 total_out.
Other cmds which use this internally use arraycount=4.
AcquireBlePairingEvent
No input, returns an output u8 and an Event handle with EventClearMode=1.
sdknso will Abort if the output u8 is value 0.
BlePairDevice
Takes an input BleAdvertisePacketParameter and an u32, no output.
The u32 is handled the same as #BleDisconnect.
BleUnPairDevice
Takes an input BleAdvertisePacketParameter and an u32, no output.
The u32 is handled the same as #BleDisconnect.
BleUnPairDevice2
Takes an input Address and a BleAdvertisePacketParameter, no output.
BleGetPairedDevices
Takes a type-0xA output buffer containing an array of Address, a BleAdvertisePacketParameter, returns an output u8 total_out.
The max array entries is 10.
AcquireBleServiceDiscoveryEvent
No input, returns an output u8 and an Event handle with EventClearMode=1.
sdknso will Abort if the output u8 is value 0.
GetGattServices
Takes a PID, a type-0x6 output buffer containing an array of #GattService, an u32, an AppletResourceUserId, returns an output u8 total_out.
The u32 is handled the same as #BleDisconnect. The max array entries is 100.
GetGattService
Takes a PID, a type-0x1A output buffer containing a #GattService, an u32, a GattAttributeUuid, an AppletResourceUserId, returns an output u8 total_out.
The u32 is handled the same as #BleDisconnect.
Same as #GetGattServices except this only returns the #GattService which matches the input GattAttributeUuid.
GetGattIncludedServices
Takes a PID, a type-0x6 output buffer containing an array of #GattService, an u16, an u32, an AppletResourceUserId, returns an output u8.
The u32 is handled the same as #BleDisconnect. The max array entries is 100.
Same as #GetGattServices except this only returns #GattService entries where various checks pass with u16 fields.
The param for the output u8 is unused by the sysmodule, hence the output is always 0. However, a sdknso func which calls the nn::btm::* func for this expects this u8 to be set.
GetBelongingGattService
Takes a PID, a type-0x1A output buffer containing a #GattService, an u16, an u32, an AppletResourceUserId, returns an output u8 total_out.
The u32 is handled the same as #BleDisconnect.
This is similar to #GetGattIncludedServices except this only returns 1 #GattService.
GetGattCharacteristics
Takes a PID, a type-0x6 output buffer containing an array of #GattCharacteristic, an u16, an u32, an AppletResourceUserId, returns an output u8 total_out.
The u32 is handled the same as #BleDisconnect. The max array entries is 100.
The u16 controls which #GattCharacteristic entries to return.
GetGattDescriptors
Takes a PID, a type-0x6 output buffer containing an array of #GattDescriptor, an u16, an u32, an AppletResourceUserId, returns an output u8 total_out.
The u32 is handled the same as #BleDisconnect. The max array entries is 100.
The u16 controls which #GattDescriptor entries to return.
AcquireBleMtuConfigEvent
No input, returns an output u8 and an Event handle with EventClearMode=1.
sdknso will Abort if the output u8 is value 0.
ConfigureBleMtu
Takes a PID, an u16, an u32, an AppletResourceUserId, no output.
The u32 is handled the same as #BleDisconnect.
sdknso will Abort if the user-specified u16 is <0x18 or >0x200.
GetBleMtu
Takes a PID, an u32, an AppletResourceUserId, returns an output u16.
The u32 is handled the same as #BleDisconnect.
RegisterBleGattDataPath
Takes a PID, a #BleDataPath, an AppletResourceUserId, no output.
UnregisterBleGattDataPath
Takes a PID, a #BleDataPath, an AppletResourceUserId, no output.
