while (Serial.available()

[holt24]

I'm doing something similar with a PicAXE over bluetooth, and found the ser.inWaiting() of use

while 1:
      while ser.inWaiting() > 20:

Hi thanks for that I did this.

while 1:
        try:
            msg = ser.readline()
            msg=msg.decode('utf-8')
            if len(msg) > 0:
                print(msg)

 
Now that only goes to print if msg is > than 0.
That stopped the code printing empty lines.
I will use your code next time.
