The script allows to trigger a few service functions of Dji drones. It talks to the drone like comm_serialtalk.py, but provides easier interface for some important functions.

Big thanks to Ace-Code1 for a UI for the app https://github.com/Ace-Code1/commOgServiceGUI

Example of listing Flight Controller Parameters 200-300 on Ph3 Pro to CSV format:

./comm_og_service_tool.py /dev/ttyUSB0 P3X FlycParam list --start=200 --count=100 --fmt=csv

Example of getting value of Flight Controller Parameters on Spark:

./comm_og_service_tool.py /dev/ttyUSB0 -vv SPARK FlycParam get g_config.flying_limit.max_height_0 --fmt=2line

Example of setting value of Flight Controller Parameters on Spark:

./comm_og_service_tool.py /dev/ttyUSB0 -vv SPARK FlycParam set g_config.flying_limit.max_height_0 500

Example of performing service “joint coarse” calibration of Spark gimbal:

./comm_og_service_tool.py /dev/ttyUSB0 -vv SPARK GimbalCalib JointCoarse

Example of performing service “linear hall” calibration of Spark gimbal, using Windows host:

python3 comm_og_service_tool.py COM23 -vv SPARK GimbalCalib LinearHall
