hi ,
I am new to tiny OS and for my master thesis I need to find the signal
strength of sending mote.I am using micaz motes.I am using 3 motes.Mote 1 will
send to mote 2 and mote 2 will exrtact the rssi value from the packet send by
mote1 and forward the rssi value,source id and sequence number to the base
station which is mote 3.I am using xsniffer to get the values but I am not
getting the correct output .when i read papers related to rssi it says the rssi
values almost -50,-43 etc.But i am getting 10,15 when i keep both motes
closer.the code written is as follows:
Module
uint8_t rssi ;
uint16_t sNo ;
Packet *p1=(Packet*)rm->data;
strgPkt *Smessage =(strgPkt *)strength.data;
rssi = rm->strength;
sNo = p1 -> seqNo ;
Smessage->strPkt = rssi ;
Smessage->seqNo = sNo ;
Smessage->src = TOS_LOCAL_ADDRESS;
header typedef struct Packet
{
uint16_t seqNo ;
uint8_t src ;
}Packet;
typedef struct strgPkt
{
uint16_t seqNo ;
uint16_t strPkt ;
uint8_t src ;
}strgPkt;
Is ther anything wrong in this code?can any one tell me how to interpret rssi
data using XSniffer?ANy one got any idea ypical values of RSSI values of micaz
motes?
Thanks in advance
Gayathri
