@ReemOthman we used ethernet over usb rather than WiFi. Based on our experience if you're using Linux check the firewall isn't blocking the connection as this was one problem we had. Secondly if you are on the newest firmware we had to set the address manually and then revert to DHCP to get it to connect properly on occassion (also on Linux). For some reason the connection seems to work better on windows a lot of the time.

I had tried that initially but was unable to get a USB Ethernet connection on windows. Tried it the newer model IP again now (on ubuntu) and I can SSH in without password. Thanks for the help!
Also having a bit more of a look around I found this post https://discuss.luxonis.com/d/1898-password-for-rvc3-series-3-oak-dev-kit which seems to be an identical issue however I've been unable to find the followup on github. I've also tried common passwords.

Hi Erik,
My apologies I'd accidentally copied one of the commands I tried when trying to troubleshooting in my original comment.
it's .55 I get asked for a password on .10 gives no route to host es expected.
Command;
ssh root@169.254.0.55
Response;
root@169.254.0.55's password:
Hi Jaka,
Yes, I tried leaving it empty. The other devices we have allow SSH without password for the root user however they were both on the newer IP address. So I wondered if it was something required on earlier versions of the firmware / OS?

Hi all,
We purchased several of the FFC-6P boards for development. I've had one board that I've done the majority of the development work on so far. Now we have that setup as desired I went to update the second board we have to newer firmware so I can have an identical setup to the first. I setup the network connection and noticed it was using the older IP address. I tried to SSH into the device
ssh root@169.254.0.10
and was asked for a password, this is the first time trying to SSH into this particular board do you have any idea what the password would likely be?
Kind Regards,
Jordan
We encountered a few more issues getting sensors to work as expected and also required pin numbering however everything is now working as expected. The pin names map to GPIO number as follows;
I2C4_SCL = GPIO30
I2C4_SDA=GPIO31
In case anyone else is looking for info on the GPIO pin numbering extremely useful tables are present in the OAK SOM MAX datasheet

Hi all,
I'm currently working with an FFC-6P board and I'm integrating some environmental sensors. The sensors are powered and connected to the 6P and I can see them with i2cdetect -y -r 4 so know they're present on bus 4. The issue I'm having is that I'm using Adafruits Blinka compatibility layer for circuit python and as the FFC-6P isn't a supported board it errors out.
This is fine in theory as I can use the generic Linux setup however I need to know the pin numbers/names (taken from pinmux) of the SDA and SCL pins on bus 4 to input them manually. It should look something like this; (Example from Jetson Orin)
SDA = Pin("GP16_I2C8_DAT") # I2C4
SCL = Pin("GP81_I2C9_CLK")
SDA_1 = Pin("GP14_I2C2_DAT") # I2C2
SCL_1 = Pin("GP13_I2C2_CLK")
I tried extracting the DTB from the image and de-compiling to see if I could find any pinmux info there but had no luck. Are you able to provide a pinmux table for the FFC-6P or let me know the pin names?
Kind Regards,
Jordan
Thanks Erik found most of the information needed, as a note for anyone else who may be searching the connector for aux is an Amphenol/FCI 20021121-00010T1LF
The mating connector to the PSRBSheader is a GHR-07V-S
Dear Luxonis,
I'm currently working with the Oak FFC-6P and noticed the i2c pins on the aux header. For our application it would be great to be able to attach some simple i2c sensors to this port (temp, humidity, ect) Looking through the documentation it seems that the logic level for this is 1.8v. I wanted to confirm if that was the case and also ask if these lines have inbuilt pullup resistors? Also what is the mating connector is for the AUX header and the PSRBS connector.
Cheers, Jordan
A quick note on the jetsons ensure the power mode is set to MAXN as of the other power modes will result in poor performance with depth AI
Hi I've tried it flipped and still I get the same error. Do you know if there're any other likely culprits of this issue? Also the above image was taken from the luxonis product page and shows the cable in the other orientation so if it's incorrect it might need to be updated.
