hi All,
I'm wondering to know how does the cc2420 knows the length of the address
field within the mac section of a packet. That field has a size from 0 up
to 20 bytes so, even if the receiver knows the length of the MPDU how does
the address information is handled? I'm thinking, for instance, to
Hello, Roberto;
As far as I know, the cc2420 struct is defined as:
typedef nx_struct cc2420_header_t {
nxle_uint8_t length;
nxle_uint16_t fcf;
nxle_uint8_t dsn;
nxle_uint16_t destpan;
nxle_uint16_t dest;
nxle_uint16_t src;
nxle_uint8_t type;
cc2420_header_t;
so even though it can be from 0 to 2
If you post those messages you get on the serial port and if I
recognize them, I will tell you what they are.

Hello, Omprakash!
The messages are basically like this:
7E 45 00 FF FF 00 00 13 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 53 63 7E
In the 0's there should be the CTP header and data structures (they get
correctly populated after 14 receives from the network).
Thanks,
Pedr
Could you please send the sequence of 14 pkts? Also, the node id's of
all the nodes in the network.
Thanks.

Well,
It's this 14 times,one message every time a node sends a data packet (the
CRC bytes there are wrong, i just put 0's in the middle using a normal
message as a starting point):

00 00 00 00 53 63 7E
the node id's are
Hi friends,
I wanted to know if there is support available in Tinyos-2.x for GPS
sensorboard like MTS400. Please do reply soon as I want to use this sensor
for my work.
Thanking You

Hi,
PowerTossim-2 is in testing phase. It computes energy for the following:
1) MCU
2) Radio (Rx, Tx, other internal blocks)
3) Leds
4) External memory (Limited).
I have not updated the CVS yet.
PN: PowerTossim-2 is currently supporting Mica2 platform (only CPU profiling
can be enabled in
Could you also post the tarball of tos/lib/net/ctp and the application
you are using?
