Hi, my name is Eric
I am having trouble getting ez builder connected to the ez board. I am using 2 xbee instead of Bluetooth. I can get the xbee to communicate with each other using DIGI software but not to ezrobot. Baud rate for the xbee is 9600, I am not sure what it is for ez robot? The com 3 port shows in ez builder but the pop-up saying there is no connection. I am using windows 8, can anyone help with suggestions? Thanks in advance,Eric
Upgrade to ARC Pro
Get access to the latest features and updates with ARC Early Access edition. You'll have everything that's needed to unleash your robot's potential!
Also did you use the bluetooth to establish the initial connection and download version 16 into your EZ-B ?

Another thing that's confusing is that the Labels on the EZ-B are not that of the Actually PIC chip connections but rather the Xbee/Bluetooth connections, so you'll need to have Xbee Tx connected to the port labeled Tx on the board and same for the Rx (Rx -> Rx ideally with a voltage divider in between).

"I figured Out that ARC sends a couple for Hex 55 ASCII Letter "U" to the EZ-B board as part of its initial communications test. The EZ-B board seems to respond with a Hex A0. This is most likely part of the baud rate detection sequence. This was one of the things I was hoping to find out. I have tried manually sending a couple of Hex 55 ASCII Letter "U"s to the EZ-B board using realterm terminal software through the Bluetooth COM port and received the EZ-B boards A0 response back so now I have a simple way of checking out the wifi uart board for basic connectivity with the EZ-B board."
This should work for you with the Xbee interface as a way to test initial connectivity to the EZ-B and make sure you have the Transmit and Recieve lines are proper.
