I am working with RaspBerry PI 3, Arduino and Shield, XBEE S1, configured with XCTU 6.3.11, exactly set AP mode API Enable[1].

But when I run the “SendDataSample.py” from xbee python library, I got the error:  
digi.xbee.exception.InvalidOperatingModeException: Unsupported operating mode: AT mode

What Should I Do?? Please help me…ㅠㅠ
