AVMS connection fails

Legato Application Framework
1

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

does it work for AT+WDSS=1,1

3

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 ?

4

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

5

have you tried this for factory reset?

6

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_BACKUP etc

7

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

9

yes, you can have a try on that

10

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.]”

11

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.
