DOMException: GATT operation not permitted. #28

Open ariccio opened 2 years ago

ariccio commented 2 years ago

So here's an interesting new problem. Right now in Chrome Canary, if I run the example and pair with my Aranet4, I get a DOMException: GATT operation not permitted. error. What makes it interesting, is that if I comment out the CO2 characteristic, f0cd3001-95da-4f4b-9ac8-aa55d312af0c, I have no such problem.

The way I understand Chrome, this means, that for some reason the Read bit for that characteristic isn't set?!?

What the heck?

Has anybody had similar problems?

Just checked, it's broken on OSX too. Hmm.

I just discovered something interesting - the f0cd1503-95da-4f4b-9ac8-aa55d312af0c characteristic works fine! Maybe just change to that one.
