XbeeException : Could not find port: /dev/tty.usbserial-A6005uPi

I try to run an example using the API of XBee.

When I execute the program in Eclipse, I obtain this error : 

Stable Library

Please, can someone explain what this error means? Can someone help me to find solution?

Thanks in advance :)

Solution

  • . The steps of the solution are :
    1, verify the group of ttyUSB0 : ls -la /dev/ttyUSB0 crwxrwx--x 1 root dialout 188, 0 Dec 2 10:01 /dev/ttyUSB0

    Then verify if the user "sam" existe in the same group (dialout) in this case : id -Gn sam sam adm cdrom sudo dip plugdev lpadmin sambashare ,

    In the case that the user is not in the same group it is primordial to add it : sudo usermod -a -G dialout sam

    Finaly, change the permission of ttyUSB0 like this : sudo chmod a+rw /dev/ttyUSB0

    Now if the example is put to run it will be executed correctly
