Hello there!

The issue you’re experiencing with the Colibri i.MX6ULL 512MB WB module not detecting certain 2.4GHz channels (12 and 13) could be due to several factors, such as regulatory domain settings, driver limitations, or hardware differences.

  1. Regulatory Domain Settings: Wi-Fi channels are subject to regional regulations, which can affect the availability of certain channels. Please ensure that the regulatory domain is correctly set on your device. You can check and set the regulatory domain using the iw reg get and iw reg set commands. Make sure it matches the region where you are operating the device.

  2. Driver and Firmware: Verify that you are using the latest Wi-Fi driver and firmware for the Colibri i.MX6ULL. Updates can sometimes resolve issues related to channel availability. Check your BSP for any available updates.

  3. Hardware Differences: Although you mentioned that the Verdin i.MX8MP does not have this issue, there could be differences in the Wi-Fi hardware or configuration between the two modules. Ensure that the Wi-Fi module on the Colibri i.MX6ULL is functioning correctly and is properly configured.

  4. Software Configuration: Since you are using BSP6.8 Minimal Image, ensure that all necessary software components for Wi-Fi operation are correctly installed and configured. This includes network management tools like connman or NetworkManager.

  5. Testing Environment: If possible, test the Colibri i.MX6ULL in a different environment or with a different access point to rule out environmental factors or specific access point configurations that might be affecting channel detection.

By following these steps, you should be able to identify and potentially resolve the issue with Wi-Fi channel detection on your Colibri i.MX6ULL module. If the problem persists, further investigation into the specific driver or hardware configuration may be necessary.

I hope this helps! If you have any more questions, feel free to ask.

Best regards,
Toradex AI Assistant.
