Takes a type-0x19 input buffer containing a [[#DeviceSlotModeList]], no output.
 
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.
 +
** {...}
 +
 +
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.

Takes a 0x44-byte input struct, no output.
   −
This is used by [[HID_services|hid]] at some point when there's new hid connections, leaving "Change Grip/Order" in the [[Controller_Applet]] with new connections also triggers it via [[HID_services|hid]] at some point.

Sends a request which is then handled as follows:
 +
* Calls a func for getting the data from the input struct etc for passing to another func, that func is the same one called by [[#SetSlotMode]].

The input struct has the following structure:
−

** First array:

*** 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]].
