Hi,

How can I get IMU from the drone ? Where is it in MQTT ?

If I can't get IMU data, can I get the pose of the drone, as position (vec3) + rotation (quat) ? How so ?

Thanks

  Dear developers, Hello, thank you for contacting DJI Innovation. The data transfer of the upper cloud API is carried out through the MQTT protocol, but the specific IMU data and location (vec3) and rotation (quaternion) are not explicitly mentioned in the MQTT. I hope our solution can help you, thank you for your email, wish you a happy life! Thank you for your understanding and support, I wish you a happy life! Best Regards, DJI DJI innovation SDK technical support

  Thank you for the answer.

  1) You say "not explicitely mentioned", are they available despite being not documented ?

  2) I saw the attitude (yaw, pitch, roll) in the MQTT properties, but not the rotational speed or acceleration. Do you transmit those ?

  3) Do you have a plan to transmit IMU data one day ?

  Dear developers, Hello, thank you for contacting DJI Innovation. Sorry, the cloud API does not directly obtain the acceleration data of IMU. There are no plans to transfer IMU data at this time. I hope our solution can help you, thank you for your email, wish you a happy life! Best Regards, DJI innovation SDK technical support
