Connect RPI with Bangle and send data

Hi fanoush, thanks for your patience.
So to go back I made the following changes but I stiil get no display on the watch. Just to note the function has changed to Y rather than X.
This is the console output.

Connecting...
Connected
Writing command
Waiting for data
RX> bytearray(b'Y({"Code": "10"})/n')
RX> bytearray(b'Y({"Code": "10"})/n')
Done!

Putting the command back to what is was

command = "Y("+json.dumps(dict)+")/n"

and my app function is now

E.showMessage("Hello Code");

function Y(dict) {
  E.showMessage(dict);

}
