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