I created an issue in Github last month, but since I didn't get answer, I am trying here:
Basically since December, I can't read the data anymore. Tonight I tried to reflash the old code (v017). While monitoring the Serial port, I can see the device is successfuly connecting to the server. Then the device upgrades to v031, so connection is doing OK I guess.
However after reboot, the device is still the same:
Doing my investigations, I deleted the device from espaper.com. And now I can't Register is back !
Device MAC is 68:c6:3a:85:17:af
Any help is welcome, my device is basically just a brick now !
Note: during the update to v031, I could see a black ribbon at the top of the screen telling me upgrade in progress. So I believe the screen is OK, but the data is wrongly interpreted.
