Always get "Transmitter error: Unable to parse auth challenge: timeout" with newer transmitters #148

Open goltra3 opened 4 years ago

goltra3 commented 4 years ago

Hi guys!, I'm always getting "Transmitter error: Unable to parse auth challenge: timeout" with these G6 newer transmitters that showed @ps2 in his v3.1 version.

I've:

With an older one (July 2019), it does ask me for pairing, but next it throws me an exception and app crashes. It does reset the transmitter.

Any Ideas?

Having the same issue with my new batch of transmitters (serial numbers starting with 8G). Interestingly, passive mode is also not working. Logs from active mode (ids redacted):

Shortly after that last comment passive mode started working. But active mode still fails to authenticate.

Hi @pi4ohhi7!, what do you mean with "active" and "passive" mode?

pi4ohhi7 commented 4 years ago

Passive mode eavesdrops on the official Dexcom app as it communicates with the transmitter; active mode directly communicates with the transmitter. It looks like passive mode does still work (though I'm having some trouble getting it to work consistently).

goltra3 commented 4 years ago

Thanks @pi4ohhi7!, and is it possible to reset transmitters with passive mode?, I haven't heard about that possibility... how does it work?. Thanks again!

pi4ohhi7 commented 4 years ago

It's not relevant to resetting transmitters as far as I know.

Also having this issue with 8J transmitter in the US on iPhone with iOS 13 something.

trauts2 commented 3 years ago

Same here, with 8H transmitters.

tomnis commented 3 years ago

Getting the same with an 8M transmitter.
