I see this error when I run my coordinator xbee USB to connect to device Xbee.

Contacting Xbees :

[ERROR] [WallTime: 1450911586.913302] Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

It used to work one day earlier and we have not changed any software version/code

This is how I am trying to connect

~/catkin_ws$ rosrun rosserial_xbee xbee_network.py /dev/ttyUSB6   3

/dev/ttyUSB6: This is where coordinator with address 0 is pluged in.

I did check in XCTU that it has same Channel, PAN id and baud rate 57600

I did try to change usb cables, but did not help We are using sparkfun explorer I am using Xbee S1.

Wondering if any one have seen this error and know little bit more about this.

Can you verify that the zigbee network works without rosserial (ie: you can transmit and receive data some other way)?

Yes we can transmit and receive data. Verified using XCTU. Also when I start xbee_network.py from the machine where coordinator is connected, we see that it send some frame data to node Xbee. But we do not get any response from NodeXB back . Could it be something to do with baud rate ?

I'm not an xbee expert, but I'd imagine baudrate should be properly configured, yes.

Hemant: did u solve the xbee issue? I am facing the same problem. It works the first time. Two days later "Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino". I tried installing again. It's working in X CTU.
