Pop it on your SD card.
Hold the Sync button on your bird/drone and power it on. Keep holding the Sync button for about another 10 seconds or so. You will here the FW beeps.

Once completed it will give you a different set of beeps and the gimbal light will stay Green. Power it off and take out the SD card and check it for the text file from the FW.

This has nothing to do with the RC, its just for the drone.
This also did help my range I was getting. My RC is at 1.6.8 and my drone is at 1.5.7 using the newest DJI GO App and I was able to get more distance then I have yet.
