Thanks Eric, I will try to learn how to fish and I will take time for gihub
But since new to the tinyos, I already tried my best to explain my problem. While I think you are right, it is probably lower codes over write it. So I will try to find these lower codes, but seriously, I have no idea how to locate these codes.

I suspect that you have wired a hard coded am_type at a higher level. You can call AMPacket.type but it will get over written later. However, that is just a guess. It is impossible to determine what is going on from the little bit of information you've provide. Seriously, what do you want from us? How about you think to your self what would help us help you. What code base are you working on? Better would be if you are based on github://github.com/tinyos/tinyos-main <http://github.com/tinyos/tinyos-main> and fork so you have your own published copy. Then you could push your modifications up to your public tree. Then you could point us at the tree along with what particular application you were building and for what platform. Seriously, what did you expect us to do with the little bit of information you gave us above. Most folks would simply ignore you. Hopefully I'm teaching you how to fish.
