Connect RPI with Bangle and send data

thanks for that
I have amended the code.

command = "X('+json.dumps(dict).encode('utf-8')+')/n"

and

await client.write_gatt_char(UUID_NORDIC_TX,bytearray((c[0:20]),'utf-8') , True)
          c = c[20:]

Not sure if I need both utf-8's, however I am assuming that passing this to my function I will need to decode it.
