Hai,

I have purchased a pair of xbee module, whose range is around 30 metres.  
Its modem number is not known to me,  
but beneath it shows XB24-AVVi 001 revC.  
i checked the module via the PC COM port. I checked the device using XCTU software.  
with Enable API unchecked , the modem shows communicating problem.  
with Enable API checked , modem communication shows OK  
the modem type and version is not obtained.

please tell me how to correct this.

Hi,

XB24-AWI 001 - is 802.15.4 module.

Check COM port and Baud Rate settings, try with the baud rates - 9600, 115200.

hi  
do you work with api mode 2(escaped character) or 1?  
Close Xctu and restart your PC.  
regards,
