NOTE:
If a user is using firmware version 2.1.0.1.2.5 or above in the module, during
normal operation of the module the pin WF_HNDSHKE1 should be set to „0‟. The
ONLY scenario where this signal should be set to „1‟ is when the user wants to
upgrade the module‟s firmware wirelessly.
The feature of Wireless Firmware Upgrade is not dependent on the interface
(UART/SPI/USB).
The file RS.WSC.x.x.GENR.x.x.x.x.x.x\Firmware\WFU\control_file.rps is exactly
same as RS.WSC.x.x.GENR.x.x.x.x.x.x\Firmware\WiSe_Control.S19. The former is
in a different format and is used to wirelessly upgrade the firmware, while the latter
is used to upgrade the firmware using the UART interface. Same is the case with
RS.WSC.x.x.GENR.x.x.x.x.x.x\Firmware\WFU\wlan_file.rps and
RS.WSC.x.x.GENR.x.x.x.x.x.x\Firmware\Wise_WLAN.S19
