desert-fireball-gui_classic's Issues

Error 500 when there is no internet connection

Observed recently in Oman. When the camera has no Internet connection, the basic self check status after login to GUI will not work, but print error 500. That is a bit desperate situation in the field...

after login automatic status check may confuse leostick micro

The after login status check in the Web GUI includes checking of the GPS lock status by query of leostick and parsing its reply.
However, this can happen at unlucky time when eg the internal control SW talks to leostick.
At least once this happened (on 023 in Oman)
The leostick was then no longer able to communicate, making the web GUI stuck forever - unable to perform any actions. And obviously, this failure mode of the micro means the whole system stops capturing still images and moving data to magnetic drives.
The only way to fix this is to remotely login with ssh and cold reset the system, which resets the leostick as well.
Proposed Fix:

  1. The web GUI code needs to be changed to either exclude the GPS check (and other communications with the micro) on login or
  2. (better) put there some timeout so that the user could
    a) see a message what is wrong (leostick communication timeout/failure)
    b) execute corrective action - reset the system from the Web GUI
    Note: some users are unable to use commandline.
