Ez Bv4 Disconnecting From Network

Hello all
I'm new to the EZ family so I'm not sure if this is a setting problem or hardware issue.

First I do have the Ralink wireless card but I'm able to connect to the EZ-B4 through my network so I don't think it's an issue. Second I turned off Microsoft's security suite to prevent connection issue.
I'm Running Windows 7 with all the updates.

I'm able to connect to the EZ-Bv4 "via" AP or Client mode WiFi 3165 v2016.02.29.00. I'm currently working in Client mode.

As long as I do NOT start a new project and enter into create servo profile it stays connected and reads as follows:
Connected to 192.168.1.112:23

If I enter into "Create servo Profile" to start my new project, after a few seconds I'm disconnected from the Network so I can't adjust servo's and the message below appears. Can you tell me what setting I have wrong or why it's disconnecting me?
I did try to find this exact answer but if I missed it in the forums please point me in the right direction. Thank you in advance.

Attachment was formatted wrong. Here's the port forward

I reset the EZB and put it back to default then connected "via" AP mode.
Still the same results.


I think we can rule out port forwarding then. Seems either you got another bad camera (unlikely) or there is something wrong with the EZ-B. I think you should try an exchange.

Where are you located? If you are in the Washington/Baltimore area, I would be happy to find a time to bring over a known working EZ-B to try with your computer and make absolutely sure it is an EZ-B issue and not a computer/network issue.

@Alan... in post #18 he said he got a brand new ezb4 and camera... I think it's his PC and or configuration/antivirus software etc...... Again, I haven't read the whole thread but @Novo did you try a different computer and or Windows OS version?

***EDIT*** Ok, he said brand new ezb4 he never said Brand new "second" exb4... Alan could be right maybe your ezb4 was defective not the camera? This would be an absolute rarity so if it is defective that's just plain bad luck.... I am sure robotshop will exchange the ezb4 too...

@thetechguru
I'm in Hurst, Texas "little town" Between Dallas and Fort Worth to be exact.
Wonderful offer! Thank you! But a bit of a drive ;) for us both. I have a RV trip planned your way but not till summer I'm afraid.

@thetechguru and Alan
It's just hard for me to believe too that it's the EZB considering everything works just as Tutorials / Lessons describe. The EZB connects fine unless the battery's low and the servo's work fine with pre-programed scripts. I don't have any other 12C devices to check those ports yet. However as Alan said "Bad Luck" about the EZB, well bad luck is my middle name so I guess it's possible
I'm going to try it on my laptop "Has Older WinXP loaded and see if anything changes. Not sure what to do after that except exchange it.
Robotshop is going to think I have lost my mind!
*eek*
Report back my findings shortly.

WindowsXP won't work, so that isn't going to help unfortunately.

It could be just a bad connection on the camera port (cold solder or otherwise poor connection). Everything else would work except the camera in that case.

When the V4 and camera first came out I recall someone had a bad cable and the symptom was the same, but he was able to fix the cable himself, but if it is the connector on the board, it would be harder to self correct.

Alan
#25  
Your right Alan
Didn't think about it being XP.

So I sent the Robotshop a return request, like them guys over there "they didn't think I was crazy" and they sent me a RMA.
Going to trade out the EZB and see if that's the issue.

Will take about a week to receive the new one so I will get in touch with you again then.
Mean while I guess I'll keep reading the lessons and get a little smarter about the over all functions and12C items.

Thank you Alan and Richard for the great help.
Talk to you again soon with hopefully a new engaging question.

Alan, Richard, DJ and any I missed
Thank you for all your help.

Believe it or not apparently the EZBv4 had an issue.
The new one works great with the camera.
Worked just like it's suppose to and came right up after scanning it.

I was fully expecting it to be an issue with my setup.
Anyways now I can get on with things and ask lots of silly questions.

I will be back !
Thanks guys.
#31  
I wonder if I am having the same issue. Maybe same bad batch
#32  
@dassy
Is everything I describe in this thread the same as far as symptoms go?

These guys walked me through trouble shooting as far as you could before replacing it.

The EZBv4 for me acted normal as far as connecting to WiFi and moving servo's as commanded.
The camera also showed no signs of trouble, when connected to the EZB. The Green Led came on when connected. I did inspect the cable to the camera for signs of a bad wire or bad crimp at the connectors.

The one thing I would say is probably the best check is to connect the camera to the EZB.
Open your EZ software and Do NOT load anything. "especially saved profiles"
Click everything off the screen beneath the menu bar except the connection tab/box.
Connect the EZB through WiFi to the EZ software. "EZB should confirm connected verbally and does not matter if AP or client mode"

NEXT In the tab's on the menu bar click "Project" then click "ADD"
On the new drop down menu click the "camera" tab and finally click "Camera Device"
This adds just a camera menu to the screen. On the new camera menu, click on the radio tower looking icon.
This opens a new box where the camera IP should show up, when it does click on it. The box will close and your camera video should show up on the screen after a few moments.

Let us know how it goes!
Sorry for the lengthy explanation.

Good Luck

hi everyone,

i ahve read all your comments over here thats look pretty much helpful. i am new to jd as well . as a computer science student i took jd project for my workplacement at my university. i had similar problem as well. i tried to connect with my ARC, its connect for like 10s and it disconnected. i did reboot and deleted my existiing profiles still not finding the soulution. what is the best way to find out?? and the next thing is if my laptop is connected to jd network, i am not able to use to used the univerisity Wifi- but it doesn't happen when its connect to the Uni's PC. am i missing something here ?

looking for your all answers. thanks

Is it disconnecting with the red led staying on the ezb? Check this Ezrobot related trouble shooting guide if so: http://www.ez-robot.com/Tutorials/Trouble-Shooting.aspx

If the red led is. It staying on, it’s a disconnect from WiFi saturation. Change the WiFi channel on the ezb and try again. Also, might be a good idea to give your robot a WiFi password so no one else attempts to connect to it. You might just be experiencing people connecting to a network. 

Lastly, if you want to connect to two networks at the same time (jd) and internet, either connect your jd to a known network or use two usb WiFi adapters. This is all documented in the jd getting started guide. It’s a real good idea to use the ezrovot getting started guide to learn how to use the product: http://www.ez-robot.com/Tutorials/Lesson/125?courseId=1

There’s information in there on changing the WiFi and using two WiFi adapters etc

But what i can suspect is you're trying to use an I2C device that's not connected. Or you're loading a project that's trying to connect to hardware that isn't existing. Or the controller isn't being provided with correct power source. [font=OpenSans, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"]

What all do you have attached to your i2c and camera ports? I'm not good at reading these logs but I see your log trying to start 3 i2c devices and a camera. The camera is getting an error. 

If there is no device attached to a i2c port or you have an issue with your camera your going to disconnect. Bad connections or broken wires between these devices will also cause a disconnect. 

Speaking of port problems and disconnects, another issue is if you try to send a bad command through a Uart port or have nothing attached to a Uart port then send a command the EZB will disconnect and freeze up. 

Good luck and have fun.

@DJ Sures, Thank you for the Answere. and i need some more helps. basically i have made jd all parts sepersted and joind all the parts as shown in istructions now the movements are not working correctily. if i click the 'sit'it cannot control the body it just fall down. all the movements are not correct. i don't know what't the reason.

actually , i have a few robots in my lab and all of them had some kind of issues but i took all a working parts from each robots and try to make one working. everything is fine just movements are not right. if i say move forward, only right legs move and it just fall down.

i hope you can help me sir ..

Sounds like the servos are connected to incorrect positions. You would move incorrectly if your brain thought your arm was your leg:)
