x-ctu vs. hyperterm

Post by gunterhausfrau »

I have three xbee's. I bought them used. All three seem to communicate just fine with hyperterm (though one was setup at 19200 vs. 9600, but figured that out). Now when I use x-ctu, two report back as "unable to communicate with modem", the third appears to work fine (at least it reports back with reasonable information, I have gone no further) when I do the test/query. In terminal mode in x-ctu I get the xxxOK callback on all three.

I guess two questions, any thoughts on what the issue is? is there anything that I can check in terminal that might point to the difference between the three?

Thanks.

If you can communicate with HT you should be able to query and change settings. I would check the settings of the working one against the other.

I checked the speed (but that seemed obvious, as terminal commands wouldn't have worked otherwise). Any other suggestions about what would allow communication, but not have x-ctu recognize the xbee? I thought about a reset, but the only way that I understand to reset is to jumper the pins, can I do with with the adap board? I believe the reset pin is hooked up, if there was a command from the terminal to drive that pin, maybe I could try that? I also saw something about forcing an update, but not sure if that is something to try if the xbee is not recognized.

Thanks for the help.

If you are using the adafruit adapter try shorting rst to ground when the program says it is unable to find the modem. Just short for a second don't jumper the connection.

I'm baffled, happy, but baffled. I'm playing with a linux system, was using a windows box. I was getting the same behavior, but when I unplugged the adaptor (yep, I'm using the adafruit adapt). no communication, but it did recognize the com port, and when I went to the term communication it would do the whole +++ok thing, well, now it seems to be communicating with the xbees just fine. I don't think I did anything different, but maybe all the hot swapping reset? anyway seems to be working now (not sure why), thanks for the help. I think I would have likely tossed them on the pile of misfit toys without the input. Thanks.

I was unable to get one back from being wrongly programmed and flashed on a USB to serial cable, but upon using a real comport it worked on the second try. I am guessing there is some timing issue between the reset and the commands that happens on a USB to serial.

This was using the boards that come in the devkit for the xbee - one was serial and one was USB with a converter on it. Same thing with not workign with a usb to rs232 cable and the serial port based devkit board. Had to be a PCI serial port to be reliable.
