NO DATA IN OAK-D Lite

AitorZorroza

When using the DepthAI Viewer, communication is established — for example, sensor data such as gyroscope readings can be observed — but the system becomes unresponsive while listening, without receiving any image data. The device does not crash, but it fails to produce any visual output.

Depthai Version: 2.24.0.0

DepthaiViewer output (for each 10s but without image):

Hi,

maybe it's just a problem with the Viewer. Can you try running this test script and see if you get any image? Make sure you followed the setup steps here first. If the script works, then the device is fine.

Hi,

Thanks so much for your reply. When I run the test_script, I get two black and white images (from CAM-B and CAM-C), which display correctly. However, CAM-A doesn't show any image, and its FPS rate stays at 0, indicating it's not acquiring data. Could this be a configuration or compatibility issue with CAM-A specifically?

Connected cameras:
 -socket CAM_A : IMX214 4208 x 3120 focus:auto  - COLOR
 -socket CAM_B : OV7251  640 x  480 focus:fixed - MONO
 -socket CAM_C : OV7251  640 x  480 focus:fixed - MONO

Hi,

Just to double-check—make sure you're running the latest version of depthai:

pip install --upgrade depthai

Then try running the test script again. If CAM-A still doesn’t produce any image and its FPS stays at 0, it’s very likely a hardware issue with that sensor. If the problem persists, please submit an RMA request here: https://www.luxonis.com/rma

Apologies for the inconvenience.

Best,
Lovro
