2.2.3 Device Firmware Update

The RNWF02 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
Host-assisted Over-the-Air (OTA) update

Note: For the serial DFU and OTA programming guidance, refer to the RNWF02 Application Developer's Guide.
