Hi, I'm not familiar with this problem. The error message might mean that the serial port is already in use. Is there anything already accessing the serial port? Maybe you have another program trying to communicate with the same mote at the same time?
You could try to see whether the serial port was opened by another program with the command: sudo lsof | grep "/dev/ttyUSB0" Cheers, Urs On 12/30/10 9:53 AM, [email protected] wrote: > Hi! > > I'm a master student.
