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.

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.

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.
