Set command

Downgrade prevention means that it is not possible to update an older modem firmware version to a device. Downgrade prevention applies to both Firmware-Over-The-Air (FOTA) and wired firmware updates.

If <value> is not set or is 0, the %XRFTEST and %XEMPR commands are permanently disabled after the %XPRODDONE command has been performed. To keep the commands usable after %XPRODDONE, use AT%XPRODDONE=1. If commands have been disabled with %XPRODDONE, they cannot be re-enabled. If %XRFTEST is not disabled when issuing %XPRODDONE, it remains permanently enabled and cannot be disabled later.

The %XEMPR TX power reduction feature can be used with the PTI modem firmware even if it has been disabled with %XPRODDONE.

The %XRFTEST test and %XEMPR TX power reduction features can be used with the PTI modem firmware even if they have been disabled with %XPRODDONE.pti_v1.1.x≥3
