I have recently updated firmware for 4 out of 5 cellular modems for the devices in my fleet. I do this remotely.
Each time, my devices (Raspberry Pi 3) went offline after the firmware update succeeded, though I am not 100% sure of the exact sequence. Like, I don’t know if the devices lose connectivity right away. I don’t know if the issue is specific to a firmware update, or if any modem reboot would trigger this. But each time, I lose connectivity. The only way to get the device back online is to physically reboot.
I hope to test this further, but would be happy to get any advice on how to diagnose.
This issue has occurred on devices running both:
- Resin OS 2.9.7+rev1
- Resin OS 2.12.7+rev1
The modem is a Sierra Wireless Airlink LS300.
