I have a Python app that happily reads bike power, heart monitor and cadence data.  I want to add the ability to calibrate the trainer (Wahoo Kickr Snap).  I have read loads of docs and tried several approaches but TBH I don't know what I'm doing.
When receiving data I set the mode to Open Rx Scan Mode.  Does this support sending the calibration request?  I get the impression from the documentation that the display cannot transmit in this mode.
It would great if someone could give me the set of messages I need to initialise the node and send the calibration request (I cannot find any example on the internet after days of searching and reading the docs).
