Hi all,
I have a problem with TinyOS 2.x serial communication. Take the
easy scenario: one node with BaseStation, the other with
BlinkToRadio, which is stated in Lesson 4 of the tutorials.
However, when using net.tinyos.tools.Listen, I cannot get any
message from the BaseStation node. And I noticed that the red LED
for serial transmission toggles when the node is connected to PC
without using Listen. But when I begin to use Listen, the LED is
off, showing no serial transmission at all. Moreover,
SerialForwarder doesn't get any message either...Hardware problem
can be eliminated, after I tried the Listen tool of TinyOS 1.x,
which indicates the message is received in an unrecognized format.
I noticed that the similar problem is submitted in "[Tinyos-help]
TestSerial -only sends packets ?". But I don't quite understand why
Phil mentions TOSSIM here...
Can anyone help with this problem? Thank you for your help and
patience.
I've just tested this and it works fine for me.
This sounds like an issue with the TinyOS 2.0 serial support for
Java. What OS are you running? Have you tried using the C serial
forwarder?
Phil
