Hello, everybody: I encounter a problem in my recent research as follows: I cannot send message from pc to mote reliably, so I turn on the DEBUG of Packetizer.java Then I found when PC send msg to mote through serialport, ack timeout happen frequently. I doubt whether my application has problem, so I change to Octopus which could send msg to mote, and I found success of sending msg has low probability. So I doubt whether there is some tricky thing between support/sdk/java/tinyos.jar and serial port.
Does anyone has such kind of experiences? downstream of data cannot transmitted reliably at all, most time even just fail, but when I restart the mote, at the beginning, the probability of success is high, then lower.
