So what you mean is in tinyos-1.x is impossible to bypass this problem, isn'it? Or if there is a solution in 1.x, in my project would be really important, should you explain it? Thanks very much, Cheers Daniele

Yes, this is really happening. It's a fairly nasty issue in the 1.x stack. The TinyOS 2.0 stack doesn't have this issue; it keeps track of packets in the FIFO and spools them out one by one. If a packet can't fit in the FIFO, then the radio doesn't acknowledge it.
