This is "nn::btm::IBtm".
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.
With BLE connections, the remote device may receive ATT_READ_BY_GROUP_TYPE_REQ before the BLE connection-complete HCI event. One workaround for this is manually sending the response with HCI, after the connection is ready.
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.

== GetState ==
No input. Returns an output [[#BtmState]].
== GetHostDeviceProperty ==
No input. Returns an output [[#HostDeviceProperty]].
[13.0.0+] Takes a type-0x1A output buffer containing a [[#HostDeviceProperty]]. No output.
This gets the previously initialized [[#HostDeviceProperty]].
== AcquireDeviceConditionEvent ==
No input. Returns an output Event handle with EventClearMode=1.
[3.0.0+] Now returns an additional output bool.
== GetDeviceCondition ==
Takes a type-0x1A output buffer containing a [[#DeviceConditionList]]. No output.
[13.0.0+] Takes an input u32 [[#Profile]], a type-0xA output buffer containing an array of [[#DeviceCondition]], returns a s32 for total output entries. When [[#Profile]] is non-zero, entries are only returned with a matching [[#Profile]].
== SetBurstMode ==
Takes an input [[#BdAddress|BdAddress]] and a bool. No output.
== SetSlotMode ==
Takes a type-0x19 input buffer containing a [[#DeviceSlotModeList]]. No output.
Sends a request which is then handled as follows:
* Calls a func for getting the data from [[#DeviceSlotModeList]] etc for passing to another func, that func then does the following:
* Goes through multiple arrays of [[#BdAddress|BdAddress]].
** First array:
*** Validates the [[#BdAddress|BdAddress]] with state, skipping it if not found.
*** Calls the SetTsi wrapper func described below, with the above [[#BdAddress|BdAddress]] and tsi=0xFF (Exit). If this returns false, [[Bluetooth_Driver_services#CloseHidConnection|CloseHidConnection]] is used with the [[#BdAddress|BdAddress]].
** Second array:
*** Validates the [[#BdAddress|BdAddress]] with state, skipping it if not found.
*** Uses [[Bluetooth_Driver_services#SetBleConnectionParameter|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 [[#BdAddress|BdAddress]] 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 [[Bluetooth_Driver_services#CloseHidConnection|CloseHidConnection]] is used and the loop is continued.
*** Calls the SetTsi wrapper func described below, with the [[#BdAddress|BdAddress]] and the above Tsi value. If this returns false, [[Bluetooth_Driver_services#CloseHidConnection|CloseHidConnection]] is used with the [[#BdAddress|BdAddress]].
** It then goes through various arrays again for updating state.
** {...}
Note that the above func is also called from various other funcs as well. An [[Bluetooth_Driver_services#HidEventType|event]] for opening a hid connection also triggers it in some cases.
The SetTsi wrapper func is implemented as follows:
* Uses [[Bluetooth_Driver_services#SetTsi|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.

This also uses [[Bluetooth_Driver_services#SetBleScanParameter|SetBleScanParameter]].
The [[Bluetooth_Driver_services#BleAdvertiseFilter|BleAdvertiseFilter]] is generated as follows: CondType = 7(ServiceUuid128), CondDataSize = 0x11. CondData: {128bit UUID copied from the [[Bluetooth_Driver_services#GattAttributeUuid|GattAttributeUuid]] (size field ignored), then an u8 with value 0x0 (unused)}. MaskSize = 0x10, Mask = {all 0xFF}.

= Logging =
A func which uses [[PSC_services|srepo]] is called in certain conditions (access to srepo:u was added to btm with [7.0.0+]). This is implemented as follows (as of 11.0.0):
* Loads the data for the below fields.
* Creates the report with EventId "bluetooth_crash". The ApplicationId is set to {btm ProgramId}.
* The following fields are added to the report:
** "reason": Set to an input param for this func.
** "radio"
** "gamepad_pairing"
** "llr_notify"
** "ble_scan"
** "bluetooth_mode": Set to hard-coded value 0.
** "wlan_mode"
** "classic_device_count"
** "slot_mode_active_count"
** "slot_mode_4_count"
** "slot_mode_6_count"
** "sniff_mode"
** "ble_device_count"
** "ce_length_2_count"
** "ce_length_4_count"
** "ce_length_8_count"
* Saves the report and returns.
