2.3.3 Device Firmware Update

The WILCS02 Module is available for purchase with pre-programmed firmware. Microchip periodically releases the firmware to fix reported issues or to implement the latest feature support. There are two ways to perform a regular firmware update:

Serial DFU command-based update over UART
Firmware Sideloader

Note: For the serial DFU and Firmware Sideloader programming guidance, refer to the WILCS02 Module Application Developer’s Guide.
