Oh! I guess you have to put it in RAW mode. I should do this automatically, but I don’t have a device to test with.

Connect to the device and enter MODE RAW

On the Server Logs page, enter “signalk:streams:serialport,canboatjs:ydgw02”, and turn on “Remember Debug”, then restart, this should give us some more info in the logs.
