• Okay - got it solved! It was due to the iOS Bluetooth caching. Since I had connected to the device at some point, it cached the initial service and characteristics (which were only read). I did try turning Bluetooth off at the swipe down menu but this apparently did not clear it.

    To clear the iOS bluetooth cache I do this:

    • settings > Bluetooth > Turn off - wait a bit, turn back on

    This did the trick, and now setting notify works correctly, and I get notifications! Woot - go espruino!
