Hi! 
I have a m500 drone from modal AI. I have been following the 'getting started' guide provided [here](https://docs.modalai.com/voxl-m500-getting-started/). I am able to connect to QGC from voxl and can see the red marker (in the QGC) rotate as I rotate the drone. However, I am not receiving any position information from the QGC. When I open the MAVLink inspector in QGC the planar coordinates (x, y) are always zero even when I translate the drone for a few meters. ![modal-ai-no-position.png](https://forum.modalai.com/assets/uploads/files/1632351737845-modal-ai-no-position-resized.png) 
The floor is textured so I do not think its due to the lack of features.
Here is my voxl-vision-px4.conf file: 
{
    "qgc_ip":   "192.168.8.64",
    "en_localhost_mavlink_udp":	true,
    "en_secondary_qgc": false, 
    "secondary_qgc_ip": "127.0.0.1",
    "en_vio":   true,
    "en_voa":   false,
    "en_send_vio_to_qgc":   true,
    "en_send_voa_to_qgc":   false,
    "en_mvl_video_stream":  false,
    "en_adsb":  false,
    "adsb_uart_bus":    7,
    "adsb_uart_baudrate":   57600,
    "en_offboard_figure_eight":   false,
    "vio_to_ned_rotation_matrix":   [[0, 1, 0], [1, 0, 0], [0, 0, -1]]
}
I have followed the tutorial very closely but haven't had any success with the VIO. Please let me know how can I debug this and get position estimates from VIO. 
Thank you :)

Have you set your EFK2_AID_MASK to vio mode(280)?

Yes it is set to 280.

Follow this link https://gitlab.com/voxl-public/flight-core-px4/px4-parameters  and you can find our px4 parameters and helper parameters files for different features.

Under "Helpers" you'll find our "Indoor_VIO_params". Try installing that helper file on top of your existing parameters. Reboot the drone and see if that helps.

Thanks for your help. I realized that I hadn't configured the cameras correctly. I ran the voxl-configure-cameras  and set it up correctly. Now I am getting the position estimates in QGC.
