Hi,
I don't know about documentation but It is possible. You only have to do some programming. Simple MAC has functions only to acces transciever and send, receive data. Anything above, You have to do on your own. I solved it by creating "mater-multislave"
network with numbered packages...
Main device asked any slave one by one for data and slave responded.
But You can do it any way. You can create collision avoidance, acknowledges...
Look at all SMAC demo applications for inspiration.
