Hello all,

I developed a periodic sampling test application, with some sampler nodes
and a Collection root node connected to PC via serial (telosb motes). When
listening to serial port, default messages are coming like that :


7E  45  00  FF  FF  FF  FF  07  00  98  * 22  22  00  01  00  00  01 *  90
9D  7E
bytes in *...* are my payload (see below) :

typedef nx_struct MultiHopRoutingMsg {

nx_uint16_t data;

nx_am_addr_t source;

nx_am_addr_t parent;

nx_uint8_t hopcount;

} MultiHopRoutingMsg;

But sometimes i got weird packets, not supposed to come from any node. like
that

7E  45  00  FF  FF  FF  FF  07  00  18  00  03  80  FF  FF  00  00  29  DE
7E

What is the reason of such unexpected packets?
I am using LocalSleepInterval and RxSleepInterval on sampling nodes. And a
Collection tree for networking. These mechanisms can produce such problems ?

I would be grateful for any help.
