Hi all,
I've been reading some mails about the meaning of the fields rxInterval,
timesync, tx_power and timestamp of the metadata of an CC2420 micaz mote. But I
can't understand the meaning, I'm confused.I'm loging all the packets received
by the BS to a file, just to monitor all the parameters. Serial Header, Packet
Header and Metadata Header. More or less I've guessed which are the meaning of
most of the field , but not for these I've said above.
I've read some TEP, but I haven't found these answers..
typedef nx_struct cc2420_metadata_t {
nx_uint8_t rssi;
nx_uint8_t lqi;
nx_uint8_t tx_power;
nx_bool crc;
nx_bool ack;
nx_bool timesync;
nx_uint32_t timestamp;
nx_uint16_t rxInterval;
- What's the real meaning of rxInterval? In my log always appears as '0'.
- The timestamp, are the ticks between two recieved packets?
- If I transmit with powerlevel (CFLAGS += -DCC2420_DEF_RFPOWER=3) this field
is supposed to be filled with '3'? In my log always appears as '0'.
- And my last question is, timesync =1 whether I'm using time syncronization?or
what's for? In my log always appears as '0'.
Thanks for your time.
I'm looking forward to hearing from any help. Any tips are welcome.
Cheers.
David
