/*
|
|
* Nintendo Wii Remote devices require the bdaddr of the host as pin input for
|
|
* authentication. This plugin registers a pin-callback and forces this pin
|
|
* to be used for authentication.
|
|
*
|
|
* There are two ways to place the wiimote into discoverable mode.
|
|
* - Pressing the red-sync button on the back of the wiimote. This module
|
|
* supports pairing via this method. Auto-reconnect should be possible after
|
|
* the device was paired once.
|
|
* - Pressing the 1+2 buttons on the front of the wiimote. This module does
|
|
* not support this method since this method never enables auto-reconnect.
|
|
* Hence, pairing is not needed. Use it without pairing if you want.
|
|
* After connecting the wiimote you should immediately connect to the input
|
|
* service of the wiimote. If you don't, the wiimote will close the connection.
|
|
* The wiimote waits about 5 seconds until it turns off again.
|
|
* Auto-reconnect is only enabled when pairing with the wiimote via the red
|
|
* sync-button and then connecting to the input service. If you do not connect
|
|
* to the input service, then auto-reconnect is not enabled.
|
|
* If enabled, the wiimote connects to the host automatically when any button
|
|
* is pressed.
