* Scans for and connects to any BLE device advertising the HID service UUID
|
|
* (0x1812). If a previously bonded device address is stored in NVS it is
|
|
* tried first; otherwise the strongest-RSSI device found during a scan is

* Button mapping (hardcoded, no pairing config):
|
|
* VOL_UP (0x00E9) -> FSM_OVERRIDE_JACK_UP
|

* VOL_DOWN (0x00EA) -> FSM_OVERRIDE_JACK_DOWN
|
|

|
|
* NEXT (0x00B5) -> FSM_OVERRIDE_DRIVE_FWD
|
|
*
|
|
* While a button is held the matching pulseOverride() is called every
|
|
* BT_HID_REPEAT_MS milliseconds so that the FSM keeps re-arming the pulse.
