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](https://shop.luxonis.com/collections/all-in-one-dev-kits/products/depthai-rpi-compute-module-4-edition) 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"#p3375 , 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

@"erik"#p3404 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"#p3405 , 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". DM1097 R2M0E2

Broadcom#2711ZPKFSB06C0T. I received the kit last week

Hello @"mohabsi"#p3418 , 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.

Awesome, thanks for testing and confirming @"mohabsi"#p3438 !

Hi, @"erik"#p3436 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"#p6942 , 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. [URL=https://i.imgur.com/spTd5yL.jpg][IMG]https://i.imgur.com/spTd5yL.jpg[/IMG][/URL]

OAk-D-CM4 over Wifi (drivers)?

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

erik

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

kohani

Thank you, StepanKroupa.

kohani

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.

erik

Hi kohani ,
We for the inconvenience, please contact support@luxonis.com and we will take care of it.
Thanks, Erik

kohani

Thank you, erik.

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

kohani

Hi StepanKroupa,

Just to clarify, did you mean a blank app? If so, then install failed with the following output:
Error: unable to start container "1d1df8f2c2ce39ab5506728f3442be71ca79d3f2550c232d0c4f31bc2c78d41d": crun: opening filememory.maxfor writing: No such file or directory: OCI runtime attempted to invoke a command that was not found

Please see the screenshot for settings and output.

StepanKroupa

kohani Hello again,

I am sorry about this issue it is a known one - we have a fix for it but its not yet deployed. To fix it on your machine, please add cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1 to the end of the first line of /boot/cmdline.txt. After rebooting the CM4, this installation issue should no longer occur.

Hope this helps!
Stepan

kohani

Thank you, StepanKroupa. It worked perfectly.

Hi @StepanKroupa @erik I got the OAK-D CM4 with a Tenda USB Wi-Fi dongle in the box:

It shows no wireless LAN available and there are some issues/glitches with OS also, can I install official Rpi OS or is there any OAK-D flavor of OS available for fresh flash?

CM4 on back is this:

erik

Hi AnshumanFauzdar ,
You can use the standard RPI OS and then just install depthai on it (https://docs.luxonis.com/projects/api/en/latest/install/). We also provide precofnigured images (so they already have depthai & dependencies installed) here: https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/raspberrypi/
Thanks, Erik

AnshumanFauzdar

erik Thanks for this, the folder contains images for PoE version but mine is OAK-D CM4 is it same for both?

Can I power this module with micro usb through USB_BOOT slot disabled?

and any help on Wi-Fi dongle driver installation?

erik

Hi AnshumanFauzdar ,
Yes it should work for your cam as well, there isn't much difference.
The usb-boot is for flashing (emmc, see here), I don't think you can power the whole board through it. Does the dongle not work by default with newest RPI OS image?

AnshumanFauzdar

erik

Thanks for this clarification
Got it, if it would have type C or this boot_USB it would have been nicer to work in production environment. Is PoE supported because I can see pins labelled with PoE hat CT1, CT2, SP2, SP1, if yes where can I get it?
I have not flashed new OS yet, will try and update here.

AnshumanFauzdar

erik I flashed with the newest RPi OS and still dongle is not detected, when doing lsusb, I am getting the list with the device in it:

Bus 001 Device 007: ID 0bda:b711 Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (After Modeswitch)

and I followed following post and I am getting on make step and errors are like this:

make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/6.1.21-v8+/build M=/home/cm4/Downloads/rtl8188gu modules

make[1]: *** /lib/modules/6.1.21-v8+/build: No such file or directory. Stop.

make: *** [Makefile:1895: modules] Error 2

erik

Hi AnshumanFauzdar ,

Looking at the schematics I believe it should, just note that the SOM heatsink will be in the way, so you might need extension header (like this), so you'll be able to connect the POE hat onto the OAK-D-CM4.

AnshumanFauzdar

erik Where can I get the PoE hat? Buy link will be appreciated. Thanks

erik

Hi AnshumanFauzdar ,
We don't have our own POE hats, but any from Amazon (for rpi 4) should work.

AnshumanFauzdar

erik Thanks!
