Hanging/losing connection

[mikefsway]

Occasionally the pi/display seems to stop updating properly (at least on the Agile display). For example, yesterday it did not switch over to the rolling hour by hour progression at 4pm. I restarted the server and it immediately updated to the new view. Because of the eink screen it is hard to see if it isn't updating, which could be a problem if you just glance at it and it is showing the wrong day. Is there any way it can perform a check itself to see if it is running properly, and restart if not?

Thanks for reporting this one, Mike. I've seen intermittent updates issues with my version too, they've always been related to internet/wifi connectivity. There are a few options to help diagnose and fix this:

• I need to add some additional debugging & logging so that we're able to properly diagnose this when it happens (this is a code fix I can add in fairly easily)
• as you've said, there's no feedback given about the last update time on the Agile display. So, some better user feedback is required on the screen, the simplest option being the same 'last updated' time as per the other screens, but even better would be the last updated time, but if an update failed, a warning sign or icon that the last request failed.

Adding in some debugging code is going to be my first priority, as this will generally improve the codebase. In the meantime, one quick and simple test to see if this is indeed related to wifi connectivity is to move the display closer to your router and see if that makes any difference?
