I was considering implementing a transparent gateway mote that would
simply forward all packets received on the radio to the USB port. Like
a T2 version of TOSbase. As I want to maintain the serial packet
format, instead of operating on raw byte data, I was looking for a way
to keep all header fields intact. Or is there another simple way to
instantiate 256 instances of AMSend?

Can I ask why you are trying to dynamically change the value of the AM
type at runtime via this interface? The traditional way to "change"
the AM type is to include multiple instances of SerialAMSenderC() in
your configuration, each instantiated with a different AM type. When
you want to send a message with a particular AM type, you choose the
proper instance of the AMSend interface provided by one of these
components.
I'm not sure exactly why what you were trying to do originally
wouldn't work in theory, but I suspect it has something to do with not
using the proper components in your configuration.

Hi,
Using tmotes on tinyos-2.x, I am looking for a solution to manually
set the AMtype field of an AMPacket that I send out over the serial
port. When I set it using the AMPacket.setType(..) method prior to
calling AMSend.send(), it seems it is always reset by
SerialActiveMessageP.nc. But even if I uncomment line 63 in the
AMSend.send() method of that file, things don't change:
// [... ]header->group = TOS_AM_GROUP;
//header->type = id; // Commented out
header->length = len; [...]
However, if I enter any arbitrary number here (such as: header-
>type =
4;), it appears correctly in the data stream over the serial port.
How
can that be - browsing the source code doesn't show up any other
methods handling the packet in the meantime.
Any other solutions are appreciated.
Thanks,
Andreas
