Hi Fernando,
When you are logged in as your user (without sudo), your user apparently
doesn't have access to the serial port. The access to the serial port
happens over a virtual file (device file), whose permissions behave the
same as for regular files. Instead of changing the serial port's

The TinyOS environment programs the node id by modifying symbols in the
compiled binary before flashing it to the mote. I think this is compiler
and platform dependent (since where the symbols are placed and how to
access them would depend on the binary format and be platform

Hello,
How i can determine if a packet in RX fifo is a SACK packet ?
If the cc2420_header_t-length is 5 bytes (2B FCF + 1B DSN + 2B FCS)
i can say that is a SACK packet ?
Thanks.

You can do it in your code. I assume you want to do it as a permanent

You could also have some code that saved your preferred ID in the

It's called TOSSIM.
