debugging software via https://www.dji.com/cn/matrice-300/downloads as shown
in the picture below. Notably, do not use DJI Assistant 2, DJI Assistant 2
does not support M300 RTK tuning.
Step 2: Open Onboard SDK APP ID service in DJI Assistant 2 (Enterprise
Series) for debugging software, as shown in the figure below:

Step 3: Enable the OSDK API control function in DJI Assistant 2 For Matrice
tuning software, as shown in the figure below：
1）Select "Start API control"
2）"Baud rate" select 921600
Step 4: Close the tuning software after setting the parameters and restart
the drone twice. After waiting for five seconds for power on, if the control
box status light shows a green light blinking once a second, it means that
the OSDK function is opened and completed, otherwise it should be re-tested
whether the set parameters are effective. Note: Every time the drone
performs upgrade or downgrade operation, you have to turn on the OSDK
function again to use the flashing light.
