API Documentation

Hi Chad,

super cool project ! Where did you find the Bluetooth API spec for the trainers? Took your software for a spin yesterday 👯

Best,
Bernhard.

I remember starting here with the web Bluetooth API's

https://developers.google.com/web/updates/2015/07/interact-with-ble-devices-on-the-web

And unfortunately, the docs I used to make sense of reading data from the bike sensors directly are no longer online. They used to live here:

https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.characteristic.cycling_power_measurement.xml

I'm not sure if those docs exist anywhere anymore.

Here's my code for handling the cycling characteristics which might help:

Thanks so much :) Is it possible, that they just deleted the UI and that this is the underlying document? For future use: also atttached.

org.bluetooth.characteristic.csc_measurement.xml.txt

Yeah, I do believe that is the case. The old docs were just much easier to consume.
