I have tens of devices installed in different places working with OS 0.7.0 version since almost half a year. Since ~last month I had some devices that stop publishing data without any apparent reason. It seems that the connection is OK (diagnostics show all fields green), and ping reaches the device successfully. The only solution seems to restart the device.
Is there any clue to how to debug it? All local devices that I test doesn’t show this error, and the code was working sucessfully since a long time ago. Maybe some change in the Particle cloud might prevent some events to be published?
