Hello,

Sorry, the documentation has not been sufficient for this command. The XPRODDONE command should not be used as you have indicated. This command should only be used when production is done. When first used, the command cannot be re-enabled.

We are sorry for any inconvenience this may cause, and will replace the board if needed.

Kind regards,
Øyvind

Kind regards,
Øyvind

Its not working for me. AT+CFUN=4 returns OK, AT%XPRODDONE=0 returns ERROR. Some info:

%HWVERSION: E244

%SHORTSWVER: nrf9160_1.1.1

nRF9160-SICA

Thanks

Hello,

Please issue AT+CFUN=4 before issuing AT%XPRODDONE=0, this worked for me.

If this did not work, Can you please provide some information on what modem FW version you are running?

Kind regards,
Øyvind
