No such file or directory error **solved**

[drummonb]

Weather Underground is reporting that my station goes offline at least once every 24 hours. Rebooting Meteobridge solves the problem. I'm running Meteobridge 3.1 in an Airbridge Kit (Airbridge receiver + Weatherbridge for Vantage Vue) from Ambient Weather. Previously, it worked for over a year without issues.

The error message below posts every 30 seconds.

Code: Select all

logger (21.11.2016 15:04:01): station 0 (Meteostick Vantage), can't open device /dev/ttyMH: No such file or directory

I can provide remote log-in if that's helpful.

Thanks!

error message tells that the USB connection has dropped. Please check cables to the meteostick,
may be something has been pulled out a bit over time.

[drummonb]

I reset all the cables but it continues to go offline with the directory error after it runs successfully for about 25 hours. Ram is consistently about 87%. The Weatherbridge is wireless.
Do you think it's a hardware issue?

[admin]

I just released an update fixing some RAM usage issues. Please give it a reboot and try again.
Hard to say if HW had failed, especially, when it starts working fine and then drops after a while.

I really appreciate your help with this!
I rebooted with build 10756. The new version stopped the 25 hour offline cycle, but the error remains, it just seems to get past it on it's own now. See log below.

Last messages indicates that it now works.

As it works fine for all other users, please check your cables, etc.
You don't need a USB hub using Meteostick.

I think we solved it, and your first instinct was right. I removed the USB cradle that Ambient Weather supplied for the Meteostick, and plugged the stick directly in to the bridge. I've now gone five days without a data drop. Thank you!!

Usually the cradle improves RF reception significantly. If your cradle is doing
USB connnection drops, the cradle might be defective.
