The firmware tools described below can be used to do all sorts of fun stuff on your DJI device. The two main things that are of interest here include sniffing and interpreting comms to your aircraft, and firmware tweaking.

Install your toolchain as per the instructions here. You only need to do this once… but check the instructions to see if there are any new tools that you may need.

You could use the original redherring method, but the pyduml method of gaining root access is a more elegant method.

If this is your first time using phantom-firmware-tools, you will need to checkout the code from git.

cd ~/Documents/
git clone https://github.com/mefistotelis/phantom-firmware-tools.git
cd phantom-firmware-tools

If you have done this before and you want to make sure you have the latest code, you just need to sync to the most recent version

cd ~/Documents/phantom-firmware-tools
git pull

python3 comm_serial2pcap.py -b155200 -f /tmp/wsf /dev/tty.usbmodem* /dev/tty.usbmodem*
