I think it might be a bug in BaseStationCC2420, where it is not correctly
copying the source address over. Instead, you're seeing two bytes of the
15.4 packet, which are aligned differently. Rather than this:
msg = uartQueue[uartOut];
tmpLen = len = call RadioPacket.payloadLength(msg);
id = call RadioAMPacket.type(msg);
addr = call RadioAMPacket.destination(msg);
It should be doing something like this:
am_addr_t source = call RadioAMPacket.source(msg);
msg = uartQueue[uartOut];
tmpLen = len = call RadioPacket.payloadLength(msg);
id = call RadioAMPacket.type(msg);
addr = call RadioAMPacket.destination(msg);
call SerialAMPacket.setSource(source);
I just verified that this is the problem. I'm testing the code now, and
will check in the fix shortly. I fixed it in both directions. Note,
however, that the radio stack by default fills in the source address. So
in the current implementation, the BaseStationCC2420 is not a perfect
bridge, as packets will come from its source address. I'll talk with
Jonathan on how to fix this.

I don't know if you are aware, but BaseStation has the same bug.
