Little insight into the TOS_Msg attributes:

1) length – The length of the payload in bytes.
2) fcfhi – The HI byte of the FCF
3) fcflo - The LO byte of the FCF
4) dsn – The sequence number
5) destpan – The destination PAN ID
6) addr – The destination Address
7) type – The type field
8) group – The group field
9) data[28] – The data payload (28 bytes)

I also need some insight in this. Please tell me what significance the following six (marked with ****) attributes have in struct TOS_Msg.

typedef struct TOS_Msg {
// The following fields are transmitted/received on the radio.
uint8_t length; 
uint8_t fcfhi; ****
uint8_t fcflo; ****
uint8_t dsn;   ****
uint16_t destpan;  ****
uint16_t addr; // Is it a source address or Origin Address ****
uint8_t type;
uint8_t group; ****
int8_t data[TOSH_DATA_LENGTH];

uint8_t strength;
uint8_t lqi; ****
bool crc;
uint8_t ack;
uint16_t time;
} TOS_Msg;


Thanks in advance.

Sumit

In CC2420 based radio packet TOS_Msg has a attribute by name destpan. What does that indicate?
