Box tried to ping heart before networking is ready #132

Closed amcewen closed 4 years ago

amcewen commented 4 years ago

When it first boots up, the miab-brain software pings heart to let it know its version, etc.

Now that it starts up quickly, it often manages to try that before the networking has finished connecting to the WiFi (this is probably why Brittany's box hadn't reported that it was at v1.0.0)

You can see the problem if you look at journalctl on the box when sshed in, e.g.:

I think the best fix would be to delay the "ping heart" for ~10 seconds, to give the networking time to come up

Noting here too that using the "update" card will work round this, as it updates the IP address as part of the checking for new content checks.
