XBee-PRO ZB (S2C) TH - InvalidOperatingModeException: Could not determine operating mode

LorenzoBottaccioli commented 5 years ago

Hi all,

I have conncted a Digi XBee-PRO ZB (S2C) TH to my desktop. If try to connect to the device with the following code I get the following error:

from digi.xbee.devices import ZigBeeDevice 
PORT = "/dev/ttyUSB0"  
BAUD_RATE = 9600 
device = ZigBeeDevice(PORT, BAUD_RATE)                                                                                                                                       
device.open()

   1260         if self._operating_mode == OperatingMode.AT_MODE:
   1261             self.close()

InvalidOperatingModeException: Could not determine operating mode

If I open than XCTU and try to connect the device it works from both XCTU and Python.

Any suggestion to solve the issue?

Best,

Lorenzo
