I pulled an EZB -v4 out of the closet today wanting to use it as a bench tester for my robot. I cant seem to have ARC connect to it over Wifi. ARC can find it but won't connect. Here's the debug info I get. Can you guys see anything? :

All those Zeros at end is a bad sign,the last 2 times I caused an accidental short on one of the signal pins,the comm board had to be replaced both times, it would also do those long Zeros until new board put on.Jer and DJ would know better ,just reporting what I observed.
Did any of the steps in the connection diagnostic page help you? When a failed connection, there's a window asking to view the diagnostic page. There's a flowchart on there with steps to follow. Here's the direct link from the support section: https://synthiam.com/Support/troubleshooting/Connection-Troubleshooting
Is there anything connected to the ezb?
Are you using a blank project with no controls? Any controls that use I2c or any devices that arent connected will cause an error
Sorry for the lack of info.
No nothing helped. No Nothing connected Yes, new blank project with only one serve control installedI pulled out a different EZB from the closet. ARC connects perfectly after setting it to Client Mode. The problem must be in the old EZB. I know you guys don't support EZ-Robot stuff. Anyway, At some time in the deep dark past I had done a couple mods on it. It's probably ready for the bin. Thanks for the help.
Does the EZ-B make a startup chime or sound when it resets? I'm guessing the bottom board is damaged if it doesn't make those sounds.
Thanks DJ, The speaker is in place but it makes no sounds.
hi dave
when i use a new ezbv4 or a iotiny and try to connect it . i have to try several times before it connects . i had a microsoft phone ones .had to try 8 times before it would connect . maybe you can try electronic spray clean ,
If speaker doesn't make sounds then the bottom PCB is damaged and needs to be replaced. The TOP PCB is fine however
Yep Dj is right I have a bottom board coming because the old one stopped making sound after too much voltage was added.
It's a dead unit. I probably ruined it and didn't know it long ago. Thanks for the help.
Hey Dave, I did something like that too with my very first Ez4, I was trying to find a power issue and bypassed the Fuse,then forgot to take out the bypass. Found just a wire was not connected,fixed it.Then recently still using it ,added too much voltage. The fuse was still bypassed! Blew the bottom board,sound everything! Always keep a fuse there !Glad to say it is now still working with new bottom board.:D
Agreed. Fuses rock. They have saved my butt many times. I have a bad habit of pushing the limit and trying to find out how much things will take. Then I get excited and go too fast. BOOM, FRY, SMoke. LOL.
Thanks goodness that these devices are cheep (mostly).
