Send back the v3 board, not the developer kit.

The EZ-B v3 was discontinued almost 5 years ago and is no longer supported by ez-robot. It may work in newer version of ez-builder, however, there's no support from ez-robot for it.

Also, the actual error you are receiving is...

Which i pulled directly from your log file. It is important to read the error, as it explains what the error is. The error is that you're attempting to connect to a device which is not an ez-b v3. If you wish to use the v3 before sending it back, a firmware upgrade may be necessary. But, you should at least ensure you've added the v3 to the PC and follow the instructions. The last bit of v3 instructions are located here, in the learn section:

Maybe you can have one last kick-off with your v3 before it gets sent away:)
Thanks DJ.

I also encountered that message but wasn't quite sure about it since I'm using an EZ-Bv3+ board which came with the Dev Kit.

Note that, I already followed that tutorial from your link (among all others), several times, removing and adding it on Window's Bluetooth devices list. The error log that I get from the Update Firmware Log is this:


2/13/2017 2:49:00 PM - Connection Failed: System.ArgumentOutOfRangeException: The maximum baud rate for the device is 115200.
Parameter name: baudRate

2/13/2017 2:49:00 PM - Disconnected
2/13/2017 2:49:00 PM - Connection attempt error

Available Ports:
- COM5
- COM6

This happens every time. The problem is I can't update the firmware because the Update Software wouldn't even make a connection.

In any case, I'll tinker for a few bit and see.

Sorry, I know this is not the right thread for support but it might help others.
Hi DJ,

Thanks for helping with my last comment on the boards today. While looking for a resolve for "System.ArgumentOutOfRangeException" error I am receiving on my EZBv3 board during firmware upgrade, I came across this forum page "Ez-b V3 Buy Back Program" Am I eligible to return my EZBv3 for a credit to purchase some goodies on I'd like to upgrade the a newer version of the board if possible.

Thanks for the great platform:D

Hi @SubBass100,

Yep, your EZ-Bv3 is still eligible for the buy back program just contact Customer Support and let them know that you are sending it back.
While digging through a box I found 2 EZB 3's. This buyback still alive?
