Building a peer-to-peer 802.15.4 + bandwidth issue

[lex4098]

Hello, i have some problems with peer-to-peer network under 802.15.4

I use freescale MAC libraries.

I don't understand how to build a p2p network: using MyStar/MyWireless there is always some PAN coordinator and all messages flow from a device to the coordinator.
(I read many other posts, like http://forums.freescale.com/freescale/board/message?board.id=8BITCOMM&message.id=1080&query.id=3226#...
and
http://forums.freescale.com/freescale/board/message?board.id=8BITCOMM&message.id=4244 )

Where can i find some source code to start it?

Then: I understood that the 250 kbps bandwidth declared is not realistic. It is like 125 + 125 = 250 kbps.
I found some slides from Freescale that say that. Do you agree with this? I mean: do you agree that the max throughtput is about 125 kbps full-duplex? Has someone tested that?

Thank you,
Leonardo

Hello.

Please help me with the topic.
I can't build a peer-to-peer network: how can I build a network without coordinator?
I need two devices to communicate without coordinator.

Thanks,
Leonardo
