This is a Bluetooth HID media controller, with play/pause, skip forward, skip backward, volume up, and volume down commands. To use, program your Puck JS with the contents of the media_control.js file.
You will need to disconnect and un-pair your Puck in order to use the media controls, as the available services will have changed. Recommended use is paired with a phone using either a media player app (music playback or video) or a remote control app.
The operations are as follows:
-
play/pause: a short click (less than 0.3 ms). Accompanied by a flash of the Green LED.
-
skip forward: a longer click (> 0.3 ms, and < 2s) with the Puck sitting right-side-up. Accompanied by a flash of the Blue LED.
-
skip backward: a longer click (> 0.3 ms, and < 2s) with the Puck sitting up-side-down. Accompanied by a flash of the Blue LED.
-
volume up: start with the Puck up-side-down. Click and hold, and turn the Puck right-side-up. Volume up commands will repeat every 250 ms until you release the button. Each volume up command is accompanied by a flash of the Green LED.
-
volume down: start with the Puck right-side-up. Click and hold, and turn the Puck up-side-down. Volume down commands will repeat every 250 ms until you release the button. Each volume up command is accompanied by a flash of the Red LED.
-
disconnect: press and hold the button for more than 2 seconds, keeping the Puck right-side-up. Sending the disconnect command is accompanied by a flash of both Blue and Red LEDs. When successfully disconnected, the Puck will flash the Red LED once.
-
connect to the last device used: any button press shorter than 2 seconds. The Puck show the Red and Green LEDs, and then flash Green if reconnected, or Red if the connection failed.
-
connect to the specified device ID: press the button for more than 2 seconds to attempt a connection with the device corresponding to the ID specified as
knownDeviceIdin media_control.js file.
