I have an FX30s that connects to the network but fails to connect to AVMS It is a WP7702 and running R15 I see these errors. Is there a way I can recover this unit. Cell connection is ok and I can get IP address from cellular network. I can also ping 8.8.8.8 Mar 21 18:06:44 fx30s user.info Legato…

No, I have tried it many times. It appears that legato code cannot access some secure storage from the modem Is there a way to factory reset the modem via AT commands ?

My other FX30s that I updated to R15 dont show this problem. Its only one unit

have you tried this for factory reset? [image] Downgrade FX30s catm from R15 to R9 why do you need to do this? Please see here where @cchenry says it is not recommended:

yes I tried flash erase as well. Maybe the modem is not recoverable on this one. AV looks like uses some secure storage parameters stored in the modem flash or maybe I dont understand it well enough. It keeps complaining about missing variables Unable to read: /avms/LWM2M_BOOTSTRAP_SERVER_IDENTITY_B…

you need to first clear the registration in AVMS server, and then register again for this module. BTW, what did you see for the WDSI notification? AT+WDSI=4479 AT+WDSS=1,1

Hi, Could you explain how to clear the registration in AVMS ? You mean delete the gateway and register it again ? Sunil

yes, you can have a try on that

Did you manage to fix this? I also have Unable to read: /avms/LWM2M_BOOTSTRAP_SERVER_IDENTITY_BACKUP error I attempted to delete the system, but wasn’t allowed… with an error message I don’t recognise. “System cannot be deleted [System in engagement period. Shall be terminated first.]”

Fixed it. “Register” allowed me to register it again, with the same IMEI / Serial. It didn’t create a new entry… still the same gateway/system. However, this fixed whatever was missing under the covers. Modem now connecting.
