When the production test is complete, the Nordic-proprietary %XPRODDONE AT command can be run. After the command runs, nRF9160 rejects the flashing of older firmware versions. AT command support for the RF test can also be disabled. For critical information, see Customer production done %XPRODDONE in nRF91 AT Commands Reference Guide.

nRF9160 supports the authentication of AT commands with the Nordic-proprietary %XSUDO AT command. For information on the use of the %XSUDO AT command and creating and storing provisioning keys, see Authenticated access %XSUDO in nRF91 AT Commands Reference Guide.
