XAFU — Firmware Update

Initiates an OTA firmware update using a SWUpdate .swu package hosted at a URL.

Format

• Set: >SXAFU1{URL};{USER};{PASS}<

Field	Description
URL	Full HTTPS URL to the .swu firmware file
USER	Optional username for protected download endpoints
PASS	Optional password for protected download endpoints

Notes

• XAFU is in the key exception list and executes even if a configuration key is set.
• Empty username and password fields are valid when the URL does not require authentication.
• For the latest stable release, use XAFUGW.

Defaults and Limits

• Set-only command.
• URL/credential length limits are enforced by downstream update logic, not by a strict parser range table.
• No default URL for this variant (explicit URL required).
