xbee point to point serial comm

[st98]

Hi,

I am currently trying to develop a telemetry wireless system to transmit serial data from an ecu to my pc. I have obtained two xbee pro 868 modules and the xbee explorer serial to set one as transmitter and the second one as receiver. I also have downloaded the X CTU software to configure the modules. Any ideas how to set them up and does anyone know if I need a unit with a UART between the control unit and the module or can I just use the explorer for that? I am just wondering if the data send from the ecu will be read from the transmitter module. Any help would be much appreciated. Thank you in advance.

Regards

Hi, We don't sell or support the pro 868's. You might find more info over at the Digi forum: http://forums.digi.com/support/forum/index

What is 868? Does that just make it European standard?

The explorer generally takes care of voltages for you and breaks out the pins to make them more accessible.

The short answer is that you will not need anything extra to do UART - just use pin 2 for data out and pin 3 for data in. Read up on page 6 of the datasheet and ask more specific questions afterwards.

Also, I'd recommend finding an Xbee tutorial to get you started - configuration is pretty easy once you know how to do it but can be tricky if you're new although I'm assuming you're using Series 2. If you're using Series 1, I've heard that it works pretty much out-of-box.

Thank you for the reply. 868 is the frequency it operates in MHZ. I am using series 2 indeed. Would I need to use one explorer for each module I suppose?

Thank You

I understand that you guys don't provide customer support for products you don't carry/not purchased here but he's a potential customer:

Buying two would probably be the easiest solution. You definitely want to use one of these along with the FTDI cable to hook the coordinator Xbee to your pc. I don't know what ecu is, but as long as you supply 3.3V to the Xbee and connect the TX/RX pins to the UART interface of it, you should be fine but mind you the spacing on Xbee's are rather small and you'll probably benefit from having a second Xbee adapter as a breakout board giving you easier access to the proper pins. The LED's will also be helpful in debugging...

Thank You very much for the information provided.
That was really helpful

Yes, by the way, the 868 MHz frequency XBees are licensed in Europe but not the U.S.
