Ez-B Camera Not Connecting To Camera Device Control

You can see error below. It has never successfully connected to the camera. ARC can connect to ez-b. Under Advanced Settings for the EZ-B HTTP page, Camera Transmit Nagle: disabled Camera Transmit Max Packet Size: 1152 EZ-B Transmit Nagle: disabled EZ-B Receive Buffer Size: 4000

Wi-fi client mode

Camera has solid LED

Any diagnostics that I can run? Any test?

Dassey, put your ezb back in Adhoc mode. You're trying to connect to an up address of, which ARC is clearly telling you is NOT an Ezb

Your ezb has been working totally fine in adhoc (default) mode. For example on 3/11/2017, you connected successfully to the ezb in adhoc mode. Go back to that made or follow the tutorials to correctly learn how to put the ezb in client mode.

Press the reset button on the ezb and DO NOT CHANGE SETTINGS. Get the ezb to work in default adhoc mode to eliminate any local network configuration issues first. One step at a time...

Then at 5:00 on the same day, you began loading ar parrot drone projects and trying to connect to ar parrot drone cameras. And then began attempting to connect to for some reason.

Maybe you can start by telling us what you're attempting to do? And also check the tutorials - as ezrobot has made fantastic tutorials. Absolutely everything is covered.


I hate rebooting the damn thing because I never know if it will remember the wifi settings because it's a btch to get them back in. It keeps locking up and I have to plug and unplug it and try again. At some magical point it will decide that I did it just right and keep the wifi settings. It's not just the wifi settings though. It's any button on the http page. If I click a button 70% of the time it locks up and I have to plug/unplug it and try again.

Regardless; it's a valid point. Verify that the adhoc connection also does not work. That will eliminate the majority of networking issues. I know the fw on the machine itself has been opened. Perhaps it's one of the routers.

Will update thread with results.



Well, I thought it was toast for half the day. Just kept flashing white LED and saying communication error. Removed both plastic cases and plugged in (using same power source) and it still didnt work. Pushed and prodded, looked for anything popping or whatever. Nothing seemed out of place. Plugged it in again and it works. When I say it works I mean it allowed me to connect to the adhoc network.

Hopefully you can see the logs. Seems pointless to post the logs again as it is the same issue.

I went to client mode and rebooted (still no shell) and low and behold it saved the settings. I rebooted a few times just to see and it seems to be saving the settings now.

But still unable to connect to the camera.

I will put the shell back on and see if it continues to power up and remember settings. I guess I can take the shell off the camera and see if that does something



Ya, no. Same issue. Its flaky as can be. The camera seemed to pull a blurry image for a single frame, but I am not sure, it was too fast. That was while on my wifi, not adhoc. This thing is so flaky. Thats all I need. Remotely mowing the grass and it stops transmitting.
