[Contiki-developers] Zigbit and TelosB frame differences using Rime

[paul k. <pv...@ho...>]

Hi,
I've have been testing 'interoperability' between a Zigbit device and a TelosB mote, using the latest version of Contiki from CVS. I built the examples/rime/example-abc.c application for both devices and installed them OK. However, there appear to be differences in the basic MAC frame formats, which prevent them from communicating together. My crude sniffer application gave the following :
>From AVR Zigbit : 
41 C8 AB CD AB FF FF FF FF FF FF FF FF FF FF 80 00 48 65 6C 6C 6F 00 14 E6 41 C8 AC CD AB FF FF FF FF FF FF FF FF FF FF 80 00 48 65 6C 6C 6F 00 10 62 41 C8 AD CD AB FF FF FF FF FF FF FF FF FF FF 80 00 48 65 6C 6C 6F 00 7C 55 
I think the Frame Control bits (41 C8) indicate a 64 bit  Source address (under RIME)

The Frame Control Bits (41 88) now indicate a 16 bit Source address, but extra bytes appear to be sent at the end of the frame. The Buffer Full message looks like a problem with my Raven USB stick based sniffer.
