AT+S.FWUPDATE
This command downloads an updated firmware image located at the named host and path. The downloaded
image is temporary stored in the internal Flash. The user should perform a procedure to save the content of the
file system that will be overwritten during the process.
Note:
FWUPDATE can be invalidated by pulling GPIO0 high during the first reset after the execution of AT
+S.FWUPDATE command. In this case, the external filesystem is erased and the FW update is not performed.
Usage:
Note:
The HW factory reset pin (GPIO0) must be tight low during F/W update. The HW factory reset can be used after
“+WIND:17:F/W update complete!”
AT+S.FWUPDATE=e,<hostname>,[<path&queryopts>],[<port>],[<TLS>],[<username>],
