Connection Question

Assistance Requested

Help bhouston with their question and receive $10 of EZ-Credit to get more robots and parts from our store. The following information was provided about their previous efforts searching tutorials for a resolution.

bhouston claims to have checked these sources:

I have had 2 EZB4's connected to my robot for some time now and connecting to them has never been a problem. Tonight, however, I can't connect to the second one. I have one setup in client mode (which connects no problem) and the one I am having problems connecting to has always been in AP mode. I have checked out all the basics to trouble shoot the problems , reset it a couple of times and replaced the EZB with another one which is brand new. Can't connect to it either.

I get this message in the debug window,
8/3/2015 9:49 PM - Disconnected
8/3/2015 9:57 PM - Attempting connection on
8/3/2015 9:57 PM - Connected to

and this window has popped up a couple of times

I have looked at the firmware update video - it seems to be old as I don't have an "update Firmware" in my EZ Builder or do I and I'm not looking in the right place.
I am running the latest version of EZ Builder.

Your help is always appreciated - Thanks

Edit; So now I tried to connect to 4 different EZB's in AP mode and I can't connect to any of them.

I have found a few conversations, tutorials and activities that may help with your question. Take a look at these links. I've sorted them by what I believe to be most relevant but that is not always the case as I'm still learning.

Also, consider reviewing the Learn section for informative lessons and activities. Check it out!


The firmware update only applies to the old v3 board as the v4 doesn't have firmware updates (at least not yet). I know you said you have the latest EZ-Builder version and tried the basic troubleshooting methods... was reinstalling EZ-Builder one of them?


Thanks Steve, I ran the "repair/reinstall" download shortly after posting my problem and it seems to have fixed the problem. I wanted to try it a few times to make sure - it's working OK now.
Thanks for your help.


your welcome. Glad you got it sorted.
