I took the speedometer sample as a starting point and stripped it down to the very basics. I´ve tested both in DevKit simulator using Chrome under Windows 10 and in My Module on my Android 11 Smartphone.
Problem: While the current speed is reported flawlessly, my own subscriptions to other channels like motor, battery and some others do not work, although I did everything like documented (https://cobi-bike.github.io/COBI.js). On the other hand, other channels do work fine.
First, I´ve spent hours searching for my mistake - found none. Then I discovered a true bug, or at least a discrepancy between documentation and code:
The static property "serialNumber" of channel motor does not exist at all. In the simulator, the console states "Uncaught TypeError: Cannot read property 'subscribe' of undefined" - and checking cobi.js file reveals that "serialNumber" truly does not exist.
Now my question is: is this the only bug or is there something else wrong with version 0.44 that keeps my code from running? Or is it me being to stupid? Does is work for you guys? Is there a more recent version?
Have a look at my stripped-down-to-the-bone code to demonstrate the issues:
