Hi ! When using Listen or TestSerial, you have to specify the communication port with :
-comm serial@/dev/ttyUSBx:speed Were x is the data port of your device, and speed depends on your mote (cf. Lesson 4). You can also set $MOTECOM variable to avoid typing again and again the comm port. As Erhan said, USB0 is usually for programming and USB1 for data (for Windows it's comX). Use both motelist and ll /dev/ttyUSB* to check available ports. If you still have connection refused, maybe another program you're running is using data from data port USB1. The way to solve that is creating a SerialForwarder on the data port with java.(...).SerialForwarder -comm DATAPORT, then programs you want to use have to use sf@localhost:9002 (check Lesson for details on arguments) as -comm parameter. Hope it helps and it's not so wrong / ununderstandable, Erwan Le 30 mars 2011 à 21:09, Erhan Uyar a écrit : > Hello, > > Today I was also working on Lesson 4 and I got it working, maybe you > should follow this steps, > > Mote-PC serial communication and SerialForwarder (pre-T2.1.1) > > * cd /opt/tinyos-2.1.1/apps/tests/TestSerial > > * make iris install mib510,/dev/ttyUSB0 > > * export CLASSPATH=$TOSROOT/support/sdk/java/tinyos.jar:. > > * javac TestSerial.java > > * javac TestSerialMsg.java > > * java TestSerial -comm serl@/dev/ttyUSB1:iris > > gateway is connected to USB0 to install code but for listening use USB1 > > -- > Erhan UYAR - Computer Support Specialist > +90(312)210 3363 - eu...@metu.edu.tr > > Middle East Technical University > Computer Center > User Support Group > > Alinti Sobit Thapa <thapaso...@gmail.com> > >> Hello, I used to solve first problem simply unplugging usb connector and >> connecting it again.
