Xbee and node-red : how to send command from coordinator listening continuously sensors data.

0 votes
I just started to use node-red with xbee (using node-red-contrib-xbee module on a Rasbperry PI)
I succeeded in listening data coming from sensors. Now I would like also to send commands to configure my remote modules. But as I am listening continuously, the serial port (/dev/tty/USB0) is busy and I have no access. How can I manage that ?

I answer to myself !
To have duplex communication you have to take care that for input and output port you have choosed the same configuration (that means the name is the same).
If you have duplicated configurations with the same parameters it will not work.
