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

Here is the output I receive when I run the example code on my mac. It hangs at the second "connected":

EDIT: Changed the wording below to be less confusing.

I am not making direct HTTP requests from the Puck but from a raspberry pi. How does one press a button on the device to trigger the HTTP request on the raspberry pi? Then after that poll the puck for the temperature?

Sorry, I am new to BLE and have been confused by hours of reading about it.
