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
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.
