Andy,

Do you have any C/C++ code for the DNT900 that I could look at? 

i,m sorry Andy just realized i have a inbox ! only code i have any experience with is basic stamp and html and most of what Ive done was twisting others code to suit my needs ,what i would do is find an open source community that has done something similar and join them and ask for help , at least you could see some of the problems and solutions they have found and build upon that  for the xbee adapter this shouldn't be to hard that's why i suggested it. this site has some info open source xbee adapter with this all you should have to do is replace the the power supply with a more powerful one and rearrange the pin outs to suit your module  . about the tx/rx project that sounds like a grand idea but has a lot of competition and pitfalls and will require a lot through testing and knowledge which i don't have

Thanks for the offer!  I'm attempting to connect to the DNT900 with an Arduino Pro Mini.  I thought I had the program correct to communicate with the radio through the UART.  However, when I view the TX line on my scope, I don't see an indication of a data stream.

I can't tell if it's a pin definition, or because the USB cable is still attached, even the program.  Can provide some direction on the set up for using the UART?

Thanks,

Joe

For the base radio, I communication with the radio through a C# program.  I was able to request the radios MAC address and it responded correctly.  I wanted to run the same test on the remote radio.

I started with the SoftwareSerial library.  I was able to write to an LCD display with this library and thought I could use the LDC display to verify my communication with the radio.

I was using different baud rates for the LCD and the radio and thought that might not work (thinking I should start simple and convservative).  I move to using just Serial for the radio and connect the radio to pins one and zero.  I have commented out most of the code to concentrate on verifying I am sending bytes to the radio.  This was when I used an oscilloscope to watch the transmit line.  It appears the data is not sent.

I am attempting to request the MAC Address.  I have not attempted any configuration.  I have the remote radio wired the same way as the base radio so I believe the pins are wired correctly.  Your thoughts?
