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.

this is REALLY draft. Needs lots more work. Also, would be good to document how to do the hardware layer as intended in freaky's example.

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.

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

cp comm_dissector/wireshark/* ~/.config/wireshark/

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

The intent is for this command to sit between two serial ports, with serial breakout and capturing the serial TX and RX streams, being duplicated into two ports. I don't have a hardware breakout yet, so I have not yet tried this.
