9. Troubleshooting client problems

9.1. Tablet upload fails with error “Read timed out”

Likely problem: slow network, large BLOB (binary large object – e.g. a big photo). For example, in one of our tests a BLOB took more than 17 s to upload, so the tablet needs to wait at least that long after starting to send it. Increase the tablet’s network timeout (e.g. to 60000 ms or more) in Settings → Server settings.

9.2. What if it crashes?

This shouldn’t happen; please note down any error details and let us know! To forcibly stop and restart the app:

Android 4.3

  • Settings → More → Application Manager → CamCOPS → Force stop
  • Then start the app again as usual.

iOS 7

  • Double-click the Home button
  • Swipe left/right until you find the CamCOPS app’s preview
  • Swipe the app preview up to close it
  • Then start the app again as usual
