Hi all,
I'm trying to create a computer-TelosB mote interface using the MoteIF
module as the basis for the computer-side code. However, I'm not sure what
code to run on the mote to allow it to send and receive messages.
My original mote code used SerialActiveMessageC to communicate with a
Microsoft Visual C++ application, which worked well. Unfortunately, the
project now needs to run on a Linux machine, which can't use Visual C++. I
attempted to use the Send Java module included with the PrintfClient code,
because I assume that the Send module and the MoteIF module use the same
underlying software. When I try to send a message, using the format that
worked for the Visual C++ code, I get an exception (below). Might it be
because the SerialActiveMessageC is incompatible with Send/MoteIF? If so,
what should I use instead?
It seems like it would be possible (but difficult) to use the printf library
and borrow some code from the PrintfClient Java module to allow the mote to
send data, but this still wouldn't help with the issue of computer-to-mote
communication. If anyone has written a mote-side module for this, or knows
where to find one, could you let me know?
Thanks in advance,
-Kyle Fullerton
