Hi,
I’m using Pixhawk 2.4.8 + Jetson Xavier NX and i’m using VINS_FUSION for localization of my drone…please help me with how can i use OFFBOARD mode and what topic i need to publish to make my drone fly and also my drone should take inputs of local position from VINS_FUSION because i’m not using GPS …
Thankyou…

Please follow this GitHub - ZJU-FAST-Lab/Fast-Drone-250: hardware and software design of the 250mm autonomous drone this could help you.

Thanks. I followed this tutorial before, but I had trouble understanding the px4ctrl package in this tutorial. Maybe I should go to learn Mavros and PX4.

Hello, the hardware I am using is the same as yours, but when I run Vins Fusion (subscribed to the IMU topic of/mavros/IMU/data_raw), it keeps prompting me to wait for IMU. I tried to change the IMU publishing frequency to 200Hz, but it didn’t work. I also tried to change the topic to/mavros/IMU/data, but it didn’t work. Have you encountered similar problems?
