4. Update the dongle software
To update the dongle software, download these files: link, plug in the dongle and execute the script. For now, the script only works for dongle version 2.0.
Plug in the USB dongle, make sure you have the Arduino IDE installed. Select the "Arduino Micro" OR "Sparkfun Pro Micro" (check HW Versions in the menu) target and the right com port. For MySensors, in the library manager, install the MySensors library, for Firmata, install the Firmata library. Then open the sketch and click “upload”.
*Please note that by flashing the dongle, the USB name (description) will be set back to the default (Arduino Micro) one. This can be changed by editing this file: “C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt”, then goto “micro.name=Arduino Micro” and change this param: micro.build.usb_product=”FanX RF Dongle”
Via the onboard 6p header, the software can be flashed directly from Microchip studio. You can use the Atmel ICE flasher, or the Atmel ISP MKII flasher. Via Atmel Studio, also the Arduino (micro) bootloader can be flashed. No example projects are available.
