Yup. It's almost like they are trying to make CNUT work (or not) like cnMaestro. CNUT was always my go to when I had a problem with cnMaestro. I had a major problem trying to load 15.1.3 Beta7. watchdog reset with fatal error - trying to clear an empty buffer - or something to that effect.
Cambium is taking a look at the problem, so not all bad.
Cambium is addressing several open CNUT issues. Can you let us know which model AP and SMs are being used and the software builds you're at and upgrading to?
Upgrading from 15.1 too 15.1.3. Using CNUT 4.11.4 and it hangs each time. The SM is out of box, no config. Upgrading before config while its on 169.254.1.1.
Update completed, failed to reboot device. Retrying with HTTP request... (SNMPIOException : Failed to get device SNMP response.,Error Code:21-Not Writable) (SITE= No Site Name)
Does that mean anything? Regardless to what it says above the device was rebooted and firmware updated.
