Nice video that's easy to understand for a dummy like me. I updated the fw on the rc through the go app, is that ok? My current fw shows 1.5.7 and it connects to the phantom great. Is there a way for me to confirm the TXT file even though I did it through the app?
Nobody seems to have addressed this yet, so....
Updating the rc firmware and updating the A/C firmware are two separate things. Yes, the rc firmware updates are done through the Go app. The A/C firmware updates are a bit more complicated. You first need to download the proper file from the DJI site. Make sure you download the correct file for your Phantom (i.e. P3 Advanced, Pro, etc.). This file is a Zip file. Once downloaded onto your computer, the zip file contains a binary file (*.bin) that you need to copy onto a micro SD card. You can use the one that comes with the A/C, as long as there is a minimum of 100MB remaining on the card. Make sure this file is in the root of the card, not in any folders.
Once the file is on the SD card, insert the card into the slot on the gimble. Then, with the rc OFF, power up the A/C. It will do its power-on self test, then beep and begin the firmware upgrade. The small led above the camera should alternate a red/green blink. This shows the update is in progress. It may take up to 20 minutes to complete the upgrade. Once complete, the led will turn a solid green and the A/C will beep. IF THE LED TURNS SOLID RED, THE UPDATE HAS FAILED AND SHOULD BE RUN AGAIN.
Once complete, shut down the A/C, and redo the procedure with each extra battery you have. The battery updates are relatively quick. The .txt file mentioned is now on the SD card, and can be read on your computer with Notepad or some similar program.
