Two way communication using Python (bleak) / Cannot discover services & characteristics

Does the code make the Puck's light flash?

It flashed!

And then use the code from https://www.espruino.com/BLE+Advertising­#node-js - either JS or Python. The first byte you get will be the button press count - so when it changes you can do your HTTP request - and the second byte is the temperature, so there's no need to request it - you just always have it available.

I will give this a try tomorrow. Thanks for the help!
