imu data is always zeros

[longlong2010]

In DJI_guidance_example

    if ( e_imu == data_type && NULL != content )
    {
        imu *imu_data = (imu*)content;
        printf( "imu:%f %f %f,%f %f %f %f\n", imu_data->acc_x, imu_data->acc_y, imu_data->acc_z, imu_data->q[0], imu_data->q[1], imu_data->q[2], imu_data->q[3] );
        printf("imu:%d\n", imu_data->time_stamp);
        printf( "frame index:%d,stamp:%d\n", imu_data->frame_index, imu_data->time_stamp );
    }

The output of imu data is always seven zeros

I change Guidance working mode to DIY by Guidance Assistant, as the docs says that While in DIY mode, IMU data can always be output without connecting to a flight controller. So what's the reason? Expecting an answer. Thanks very much.

Sorry for the confusion. The doc's description is true only for firmware version 1.3.7 and below. For the latest version 1.4.0, you have to connect to flight controller to get IMU data. If you really want this feature, you can use the Guidance Assistant v1.2 to revert firmware to version 1.3.7.

I use the Guidance Assistant v1.2 to revert firmware, but it still 1.4.0 after finished. Any help, Thanks very much.

After try several times, it works as last. Thanks very mush!

Hi @tangketan,

Thanks for your answer. Where do I get the Guidance Assistant v1.2? It's not available in the downloads page. However, since the Guidance is advertised as having the ability be used with other robots as well (and not only the DJI M100), I'd appreciate it if you enable imu data irrespective of the flight controller connection in DIY mode asap.

Thanks

Hey guys,

I want to revert back to v1.2 as I need to read the guidance's IMU data. I could not find the older version of dji guidance assistant anywhere. Could someone help me resolve this?

Thanks
