Hi,
Im trying to run the SendBroadcast example code on a S1 mounted on an Intel Edison board.

When executing myDevice.open(); I get the InvalidOperatingModeException: Could not determine operating mode. Exception.

The Operating mode is “UNKOWN”

Any ideas, please? This is the stack trace I get:

Try using the XBee modules in API mode (ATAP=1).

I’m working with S2C Programable XBEE and receiving the same exception. Already put “API MODE = ATP1”
