Have you tried receiving the data with xserve or xlisten? They can name
all incoming packets correctly. Some apps send heartbeat packets, these
could be just that.

Subject: [Tinyos-help] unexpected packets on Serial Port
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.
