Itamar,
I’m using tinyos 1.x and in \tinyos-1.x\tos\types\AM.h:
typedef struct TOS_Msg
{
/* The following fields are transmitted/received on the radio. */
uint16_t addr;
uint8_t type;
uint8_t group;
uint8_t length;
int8_t data[TOSH_DATA_LENGTH];
uint16_t crc;
/* The following fields are not actually transmitted or received
* on the radio! They are used for internal accounting only.
* The reason they are in this structure is that the AM interface
* requires them to be part of the TOS_Msg that is passed to
* send/receive operations.
*/
uint16_t strength;
uint8_t ack;
uint16_t time;
uint8_t sendSecurityMode;
uint8_t receiveSecurityMode;
} TOS_Msg;
I think you are looking in the wrong header file. Or maybe in TinyOS 2 it is
different.

Hi Oussama,
I found The Am.h file (under \tinyos-2.x\tos\types), but there was no
mention of the TOS_Msg structure.
maybe i need to look for the message_t ? is it the packet structure you
meant?
i want to know the strucure on the mac layer( if there is any)
Thanks again
Itamar
