## T-CAN485 support
|
||||
|
||||
I added T-CAN485 board support, just use the t-can485 branch. It will display states via onboard LED.

## Serial control
|
||||
|
||||
If you open a serial terminal to the ESP you will see a summary of all variables which reflects CAN messages sent to the Easylink.

Available commands:
|

```
|

ignition on/off - power up or shutdown Easylink as normal
|

ignition standby - let Easylink run in standby mode, for faster recovery after a short stop (it will shutdown after 60 minutes)

brightness night/day - set display brightness and key illumination for day and night usage

mute on/off - disconnect bluetooth and mute system
|

volume normal/lowered - lower volume and lock volume slider (for reversing)
