Anyone experience B404s that show what should be decent signal but can't reach them or get data from them. Also seeing a lot of cloud disconnects. One specific have 43% strength and 75% quality but still drops out frequently and doesn't respond to pings.
When a device has good signal strength but cannot be communicated with, the ideal thing would be to get a USB serial debugging log from the device. Even the pattern on the status LED would be helpful.
However, if it is remote, there are a few things:
The signal strength is only updated when the device successfully connects. So if the device is truly offline, it would still have the status from the last time it worked.
You also mentioned repeated disconnects, which can also occur if the device is rebooting, which could be the result of a firmware bug. Along those lines, a device that deadlocks because of a thread safety or mutex issue, would also stop responding to the cloud, regardless of cellular quality. This would be difficult to diagnose remotely, however.
Luckily I did take a log when we installed this system because it is a new product so we wanted to make sure we got as much data as we could.
Is there anything specific I should look for?
