Sterling-LWB field upgradable firmware question

Question: I believe the BCM4343W is a ROM only part.  So, I?m assuming I don?t need to have any capabilities to update the Sterling-LWB.  Is that correct? Answer: Since the Wi-Fi firmware image is stored in the SPI flash you can technically field upgrade it, however this capability is not provided ?out of the box? with the WICED SDK. The tools necessary to update the SPI flash from the STM32F411 are provided by the SDK but you?d have to develop your own code to pull the image from somewhere for example over TCP/IP and re-program the SPI flash.
