Error reading from WLL at startup

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Error reading from WLL at startup

Post by flort »

Hi,

I recently took out a Pro Subscription on WLL to enable data catch-up as I don't have a logger. I am running CMX as a service and when I reboot, the service starts but then errors when it starts to read the Davis WLL. If I restart the service then it starts reading WLL fine and does the data catch-up. Attached is the diags file.

Appreciate if someone could give me some assistance.

Regards,
Trevor

It looks like you may have Cumulus MX auto-starting and the system was rebooted. MX is starting, but the network does not look like it has connected fully at that point.

I'd look at adding a start-up delay, and/or a start-up ping of something on the internet to your config.

If you add a delay you have the option of only using that delay for so long after a system boot, that way the delay only applies after a boot, and you can restart CMX immediately once the OS has been running for a while.

Thanks Mark. I've applied a 20 second start-up delay and that seems to have solved the issue.
