We want to understand the problem or issue more clearly. So are you facing the issue with the link between AP and SM
where the SM is disconnecting from the AP very frequently
OR
In cnMaestro you are unable to on board the SM device or already on boarded SM device is getting disconnected and connected multiple times.
From the attached logs i can see the device is not able to connect to cnMaestro. Please send the config files of the AP and SM to krishna.reddum@cambiumnetworks.com to have a check for the proper config for on boarding to cnMaestro. Also mail us your cambium ID and the device MAC of AP and SM to debug the issue .
