Ezb Firmware Update Failure Help

ok all was working fine with ezbuilder until i decided to upgrade to 12 26 version. down loaded ok then tried to run firmware update program. failure program reported io exception and no com ports are visable in pull down. ezbuilder has no problem displaying corect com port just firmware utility. bluetooth device com port is correct. help as i am locked out now since my pc is one version newer then control pcb.


Upgrade to ARC Pro

Unleash your creativity with the power of easy robot programming using Synthiam ARC Pro

Reboot your computer. Sounds like a windows related issue.
Rebooting the computer does not help. I have attached the error message and the image of the file directory. Please help as I am still locked out from using EZB. The PC has the latest software, but the controller is one verison behind. I do not know how to go back to the old verison or solve this problem. PLEASE HELP!

I dont know if this will help but this is what I would try.
-Uninstall EZ-B software.

-Run windows update and make sure any optional .net stuff is downloaded. (restart if necessary)

-Install EZ-B

-Make sure bluetooth is recognizing and connects to EZ-B

-Run firmware update

:/ You probably already tried that.


That error message says you have 2011.12.05.00 and not the most current version. Something has confused your windows installation. I agree with Glick in that you will need to uninstall - reboot - reinstall

I can't explain why. If I could, I would have written windows, and it would be much more reliable:)
Success! Back building robots! I had to manually clean the registry then reload EZB
Thanks for tips
hi i have the problem that I can not update firmware

bluetooth reinstalled and now works! *confused*
but Sharp IR Radar not working? *mad*
@mitchmen, we are not responsible for the bluetooth configuration of your computer. Do not be upset at us for your computer. You re-installed bluetooth and it works - be happy, not angry.

Second, if the sharp IR does not work, is it connected correctly? Is the EZ-B being disconnected from the computer? Are you receiving an error?

You will need to take a deep breath and provide more information so we can help you.
with the v12 firmware, the IR radar worked very well for me. after the Firmware update v15.2 no functional

again a bluetooth error?

Sharp Collision works very good
Sharp IR Radar looks bad *confused*

I'll try later with my old laptop
order to exclude errors

have a nice day *eyeroll*
Does it work on another ADC port? I tested it just now and works great. Maybe your ADC port is damaged from a short?

Hi Mitchmen14

Not a good idea to grip the EZB with the Robot Arm (as your pic shows) on the Bluetooth reciever it has delicate electronics and you may have damaged it??
The last time I got a reading like that it was a bad connector. When checking the voltage with a VOM it read low. Changed it out and tadaa!
okay so on the laptop I get the same results
and I have the plug replaced
I tested ADC 0-4 and 7, but unfortunately without success
Perhaps the sensor is defective
thanks for the help

@mitchmen14 when you disconnect the sensor, and add a regular ADC control, do you see any values change while you touch your finger lightly on the Signal line of the ADC header on the EZ-B?

Also, putting a jumper between Signal and +5 on the ADC should show you a value. That will test your port to see if it is functional
and I noticed something
the ARC can not save projects on the pc
I then tested the cloud and got an error (picture)
I tried again to save a project on the pc and it worked
crazy thing

save to the cloud does not work (on my pc)
normal save works again
I'm just happy that I can save again and hope it may help

@mitchmen14 i wonder if there is an issue with encoding from your language. can you post your EZB file here?
@mitchmen14 I just looked at your cloud db files. The files were saved with an old version of ARC, just like the message states. You will have to upgrade to the latest version. Delete your old cloud files and you'll be fine going forward.

Now that EZ-Cloud is stable, you will no longer run into this problem again.

if you look at the sharp sensor when powered by the EZ-B with a camera phone not an Iphone 4S you should see a bright blue light it will show if the transmit part of the sensor is working. It is visible on a 4S but faint much brighter on a Iphone 4 interestingly

The sensor seems to work

@mitchmen14 Using a camera is not a way to check the sensor. It will only check 1/2 of the sensor. The sensor has two parts, a emitter and receive. The emitter you can check with a camera, but that is only 1/2 of it's functionality. The only way to check the receiver is by connecting it to an EZ-B. If it does not display data, then the receiver does not work.

You can check the ADC port of the EZ-B by following my earlier suggestions.

As for the EZ-Cloud. Again, you will have to delete your existing files that are on the cloud. They are from the older version.
So no idea but I give up
the whole story cost me too much time

the only thing I still like to try
is downgrade to the old firmware and builder
can you send me pls the old version v12 by email? if it is possible
sry for the many problems

Hey, Buddy! I came over from the Arduino Platform too. It is an Easy system to work with.

At times, things can be frustrating for us all , but we have to Hang in there. If you don't give up hope and keep a positive attitude , things will get better. Remember, this field is in the pioneer stage and we are ALL Pioneers. Robots haven't moved as quickly as we had hoped. But, people like D.J. is making it much easier compared to what it used to be. I have been building robots since 1975 and the field is getting better very slowly.

We all value our time and when we have to waste it, it hurts. But, don't give up and it will be all worth it in the long run. Just be patient. The other day, I felt like D.J. was singling me out and not answering my question. But, I found out that he DOES care. His whole crew is at the Maker Fair expanding their customer base and learning new things to share with us. Usually, he has Very fast service.

Best of Luck!
