Function Documentation

bt_ctl_init()

void bt_ctl_init

(

void

)

Initialize Bluetooth control, loading the persisted airplane mode setting.

Must be called before any setter.

bt_ctl_is_airplane_mode_on()

bool bt_ctl_is_airplane_mode_on

(

void

)

Get the airplane mode setting.

Returns

True if airplane mode is on.

bt_ctl_is_bluetooth_active()

bool bt_ctl_is_bluetooth_active

(

void

)

Check whether the stack is supposed to be running.

It may not actually be running yet, e.g. while starting or resetting.

Returns

True if enabled and not stopped by airplane mode or the override.

bt_ctl_is_bluetooth_running()

bool bt_ctl_is_bluetooth_running

(

void

)

Check whether the stack is up and running.

Returns

True if running.

bt_ctl_reset_bluetooth()

void bt_ctl_reset_bluetooth

(

void

)

Restart the stack from KernelBG.

No-op if Bluetooth is not active.

bt_ctl_set_airplane_mode_async()

void bt_ctl_set_airplane_mode_async

(

bool

enabled

)

Set and persist airplane mode.

The stack is started or stopped later from KernelBG.

Parameters

enabled

True to turn airplane mode on.

bt_ctl_set_enabled()

void bt_ctl_set_enabled

(

bool

enabled

)

Enable or disable Bluetooth, as requested by the runlevel system.

Starts or stops the stack synchronously as needed.

Parameters

enabled

True to enable.

bt_ctl_set_override_mode()

void bt_ctl_set_override_mode

(

BtCtlModeOverride

override

)

Set the airplane mode override.

Starts or stops the stack synchronously as needed.

Parameters

override

New override mode.
