@I_Dwyer @Chad-Sweet Hello all, has this issue been solved in and particular version, we too are facing the same issue, on HS1 the voxl-mavlink server is initiating but we are not able to see any data from this port. We are right now on the 1.5.3 build. Pls provided more info on the same.

@Chad-Sweet thank you for the link which explains the table top architecture, can you also pls share what shall be the setup along with VOXL2 to push the hardware on to a drone platform with selected motors, battery, transmitter etc.

Dear ModalAi Team,
We would like to know what all other peripherals shall be required with the VOXL2 board to get the flight control setup ready, pls mention all the components related to electronics, add on cards, cables etc. that shall be required to make a table top setup for the same.

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
@modaltb meanwhile the update becomes available, is there any other method to get a video streamed at FHD@60fps from the voxl2 module over the ethernet interface?

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
Hi @modaltb by doing so the voxl-camera-serve and the voxl-portal pumps data over ethernet but on the web portal we are not able to see any vide0 from the IMX412 camera, pls note we are using the same voxl-camera-server.conf file which @Alex-Gardner have suggested to use.

@Hector-Nevarez @Chad-Sweet @Alex-Gardner by editing the voxl-camera-server.conf file we were able to get a video stream from 640X480 @ 30fps up to (1920X1080) FHD @ 30 fps resolution for both the IMX412 camera, as seen from the datasheet the IMX412 sensor is a 12.3 Megapixel sensor and we would like to acquire highest possible resolution video stream from the sensor at 30fps as well as 60fps. Can you please let us know how this can be achieved.
P.S. In the above mentioned conf file if we provide any resolution over and above 1920X1080 the video pile line crashes.

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
Hi @Alex-Gardner I guess the voxl-configure-camera was overwriting the voxl-camera-server file, bypassing that allowed us to get streams from both the IMX412 camera via the voxl-portal command.
Refer Following image:
The required part of getting two parallel streams from 2 IMX412 camera onthe VOXL2 board seem to be achieved. I case of any further doubts on this activity will open a new thread. Thanks for your support.

To add to the above point the voxl-camera-server.conf file goes back to the default setting once the module is power cycled, refer following snapshot of the same file post power cycling.

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
@Alex-Gardner Thank you for the clarification, pls refer following screenshot of the updated voxl-camera-serve.conf file from the VOXL2 module.
{ "version": 0.1, "cameras": [{ "name": "hires1", "enabled": true, "frame_rate": 30, "type": "imx214", "camera_id": 0, "preview_width": 640, "preview_height": 480, "snapshot_width": 640, "snapshot_height": 480 }, { "name": "hires2", "enabled": true, "frame_rate": 30, "type": "imx214", "camera_id": 1, "preview_width": 640, "preview_height": 480, "snapshot_width": 640, "snapshot_height": 480 }] }Once the above file as updated we carried out the suggested steps by providing the command
voxl-configure-cameras, as stated in my earlier post there are variety of options which pop-up once the command is executed, can you please let us know which is the appropriate configuration id to be selected from the following drop down:available camera configurations are as follows: 0 None 1 Tracking + Stereo(OV7251) 2 Tracking Only 3 Hires + Stereo(OV7251) + Tracking 4 Hires + Tracking 5 TOF + Tracking 6 Hires + TOF + Tracking 7 TOF + Stereo(OV7251) + Tracking 8 Hires Only 9 TOF Only 10 Stereo(OV7251) only 11 Tracking + Hires + Dual Stereo(OV7251) Pairs 12 Stereo(OV9782) only 13 Hires + Stereo(OV7251)We have already tried out the following all camera configurations option so far and only in camera configuration id 8 we are able to get video but the video is only from 1 IMX412 sensor.

HI @Hector-Nevarez @Chad-Sweet sorry for the late response as we were tied up in some other priority work.
As instructed in the earlier post we did update the system image and also installed the voxl-sdk, also right now on our setup we are connecting only two Hires camera (IMX412) via the M0084-1 on the camera group 1 connector (J7), and no other camera sensors are there right now on the board.
Once connections are done we executed the voxl-configure-cameras where in we are able to see the following list:
We tired with the camera config ID 3, 4, 6, 8 & 13 followed by voxl-camera-server, only with camera config ID 8 we are able to get video but only of one hires camera, and for rest config ID's the pipeline fails with different errors each time.
Can you please guide us how to get two simultaneous stream from the both the hires cameras via the voxl-portal and what camera config ID should be selected.

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
Hello @Hector-Nevarez @Chad-Sweet
As per the above two threads pls find the following status of the voxl version and the information in the voxl-camera-server.conf file, pls check as the information in the camera server configuration file that you shared and the one in the current updated system is not matching. Since the files are not matching, we haven’t connected the two IMX412 camera on the camera group 1 connector (J7) yet. Pls note the systems image is updated and even installed the voxl-sdk on top of the new system image.
Pls let me know if its ok to go ahead and connect the 2 nos of IMX 412 to cameras of anything else needs to be done.

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
@Chad-Sweet yes you are right, we are integrating 2 IMX412 via the M0084-1 on the camera group 1 connector (J7) as the video states that the camera group 0 (J6) and 2 (8) are mainly for front and rear stereo camera pairs.
As of now, no we don't intend to connect any other sensor to be plugged on the board immediately, but may be later once both the IMX412 cameras are up and running we will try out the front stereo camera along with 2 IMX412 cameras.
I hope the above information clarifies our required configuration, may we know by when we shall get this next system image build.

RE: Dual IMX412 connected to VOXL 2posted in VOXL 2
Hi as per the demo video to test the cameras it is suggested to use voxl-configure-cameras service, once we run the service there is no hires + hires camera configuration option listed in the drop down list, also if it ok to connect 2 nos of IMX412 cameras on the M0084-1 camera adapter cable as in the video its is suggested to connect one hires camera on one end and the tracking camera on the other end as the device tree setting are done for the respective cameras.
