I am using the v1.0.0 sdk at_client sample project with the v1.0.0 LTE Link Monitor on an 0.8.2 nRF9160-DK board. I have upgraded the modem firmware to 1.0.0.
The AT%CMNG=1 command is returning error and I am unclear on what I am doing wrong. I have not tried this on previous versions of modem firmware, but from other posts on devzone it appeared to work.

I am attempting to view and extract the certificate authority chain credential from my working DK system and add it to a prototype board with what I presume is an empty store of credentials. But the AT%CMNG=1 command results in an error on the prototype board as well.
Is there something obvious I am missing?
Also, how much space is available for credential storage within the modem?
regards,
Steve
