Sorry if this is question is too silly. Newbie here.

Hello,

tl;rd I need to be able use the CM4 camera with my wireless router. Do you know any direct ways or have any drivers that work for you?

I recenty started using the OAK-D-CM4 and I am in a remote enough place that I don't have access to an ethernet port. But I do get a wireless signal from a company router.

I want to use my wireless dongle if the carrier board does not have WiFi modules, although I did see in the documentation that the CM4 Module has a Wireless module. But on the panel I see 'No wireless interfaces found'. (I tired a few simple tricks off of the internet but they don't seem to work.)

Are there any guides on how to ge the wireless set up going in my case?
Are there any drives I can look into for the TPLink AC1300 WiFi dongle I already have?

EDIT: I realized that there is a Broadcom chip onboard. Should I maybe just reset the Camera and try again? If so, how do I reset the Camera= I see the button, but whats the procedure?

Any update or direction would be much appreciated.
Thanks in advance,
Tarocal.

    Hello tarocal ,
    The RPi CM4 should have wireless connectivity. What's the serial number written on the CM4? As we can determine the model of the CM4 to be able to confirm whether it has wireless connectivity.
    Thanks, Erik

        Hello,

        Next to the lens, under DEPTHAI, it has DM1097 R2M0E2.

        Just to confirm it once again, the RPi underneath has the BROADCOMS chip a well.

        Hope this helps, Tarocal.

            Hello tarocal ,
            We will debug it further in the start of the next week. Sorry about the inconvenience!
            Thanks, Erik

              Can you please debug mine as well, I receive a message "No wireless interface found".

              Broadcom#2711ZPKFSB06C0T. I received the kit last week

                Hello mohabsi ,
                I have found that commenting out

                # For OAK-CM4 to show uSD card
#dtoverlay=sdhost,poll_once=off

                Inside /boot/config.txt will fix this issue and you will be able to see WiFi interfaces. I am not sure what will be consequences (CM4 won't be able to use SD card? not sure), but I have yet to debug it.
                Thanks, Erik

                    It worked! Thanks much. I can live with this as a temporary fix.

                      Hi, erik

                      I just received an OAK-D CM4 and have successfully connected via Ethernet, and it looks like #dtoverlay=sdhost,poll_once=off is already commented out in /boot/config.txt but I'm still getting "No wireless interface found" via sudo raspi-config.

                      Do you have any other suggestions to try?

                      Thanks

                          Hi kohani ,
                          Does the RPi CM4 have the WiFi module on it? I think the wireless module is marked with blue arrow, while eMMC is marked with red one.

                              Thank you for your response erik, no it does not seem like it. Please see attached photo. I also noticed a heat sync for the PI on some of your store photos. Is that something that was supposed to be shipped with the product or just shown as an option?

                              Lastly, in trying to connect the board to RobotHub I noticed it was shipped with a 32-bit os which produces ! Unsupported architecture armv7l ! error. Is the board supposed to be compatible with RobotHub out of the box or is there a 64-bit image available I can flash?

                              Thank you

                                  Hi kohani ,
                                  That explains the issue, so WiFi wouldn't be possible, except by eg. using a WiFi dongle. By default you don't need heatsink for the RPi, as also standard RPis don't have it. If ambient temperature reaches very high temperatures, then it might throttle the CPU to reduce the temperature. Stepan will clarify on RH issue.
                                  Thanks, Erik

                                      kohani Hello,

                                      In regards to the RobotHub issue - 32 bit versions are indeed not supported, so you will need to flash it if you want to connect it to RobotHub. We would recommend the Raspberry Pi OS 64-bit Lite version. This guide might be of assistance.

                                      Hope this helps!

                                          Hi erik ,

                                          Shouldn't it come with wireless capability? The store description mentions OAK-D CM4 integrates the Raspberry Pi Compute Module 4 with Wireless. I don't see an option for choosing wireless during purchase, so wondering if I need to exchange the one I received.

                                          Thank you

                                            Hi StepanKroupa,

                                            I flashed the board with Raspberry Pi OS 64-bit Lite, installed dependencies and the depthai Python library, and successfully ran the RGB demo. Finally, I installed the RH agent, and the device was discovered inside RH, however, the status seems to be stuck at "Identifying". See attached screenshot. As a result or perhaps unrelated, the video preview brings up a modal "Waiting for a stream..." but nothing happens.

                                            Please let me know if I missed something.

                                                kohani Hello again,

                                                Please go to the "Apps" tab in the sidebar on the left, Create an App, then go back to your Robot -> Perception Apps -> Install the new app. After it installs, click on the App and check the streams in Live View (on an RPI it might take up to 20 - 30 seconds for the streams to start). If the streams still don't work, please send the logs
