This is used by [[BTM_services|btm]].
This is used by [[BTM_services|btm]].
This first calls an interface funcptr, on failure 0xCA71 is returned.
[1.0.0-11.0.1] This first calls an interface funcptr, on failure 0xCA71 is returned.
A global fixed [[#Address]] is copied to stack, this stack data is then overwritten with the output from [[Settings_services|GetBluetoothBdAddress]]. If GetBluetoothBdAddress fails, this will Abort. Then the same funcptr used by [[#SetAdapterProperty]] is called with this stack data, with [[#BluetoothPropertyType|type2]]. A converted error is returned if needed.

If GetBluetoothBdAddress fails, this will Abort. Then the same funcptr used by [[#SetAdapterProperty]] is called with this stack data, with [[#BluetoothPropertyType|type2]]. A converted error is returned if needed.
The last two bytes of the stack [[#Address]] are inverted (byteval = ~byteval), then the above funcptr is called with this for [[#BluetoothPropertyType|type3]]. Error conversion is handled if needed, then this returns 0.

The first funcptr called above does the following:
The first funcptr called above does the following ([12.0.0+] this code is now inlined):
* Calls a GPIO func with param=0, [[SVC|sleeps]] for 10000000 nanoseconds, then calls the GPIO func again with param=1.
* Calls a GPIO func with param=0, [[SVC|sleeps]] for 10000000 nanoseconds, then calls the GPIO func again with param=1.
* [12.0.0+] Calls a func to update an interface object ptr to use the enabled-object. A vfunc for various interface objects are called, with Result 0xCA71 being returned if the ret is non-zero (failure after the first interface object will trigger an Abort).
* [12.0.0+] [[Settings_services|GetBluetoothBdAddress]] is used, on failure this will Abort. Then the same vfunc used by [[#SetAdapterProperty]] is called with the output from GetBluetoothBdAddress, with [[#AdapterPropertyType|type0]]. This will Abort on failure.
* [12.0.0+] The last two bytes of the stack [[#Address]] are inverted (byteval = ~byteval), then the above vfunc is called with this for [[#AdapterPropertyType|type3]]. This will Abort on failure, otherwise 0 is returned.
* Calls a func for initializing the paired-devices table (empty).
* Calls a func for initializing the paired-devices table (empty).
* Calls a modified version of BSA_Boot, which handles BSA server initialization.
* Calls a modified version of BSA_Boot, which handles BSA server initialization.
