Connect RPI with Bangle and send data

Hi Gordon,
Many thanks for the response.
I decided to make an app for this to make things a bit more visible.
However I get an error with json.dumps, which is

Traceback (most recent call last):
  File "/home/pi/bleak-test.py", line 15, in <module>
    command = b"X("+json.dumps(dict)+")\n"
TypeError: can't concat str to bytes

I added this snippet to bleak to creates the variable.

import json

[#create](https://forum.espruino.com/search/?q=%23create) dictionary for the data to be sent
dict = {'Code': '10'}

And for completeness my app does this

E.showMessage("Hello Code");

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

}

So do I have to convert the json to bytes?
Thanks for your patience
mike
