Hi
In uses I add
interface CC2420Packet as RadioPacket;
Then I called getRssi in my function
rssi = call RadioPacket.getRssi(rx_buffer_ptr);
CC2420Packet is defined as
#include "AM.h"interface CC2420Packet { async command int8_t getRssi( TOS_Msg*
strength );}
TOS_Msg in AM is defined by
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; 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;
While compiling this file, I am getting error
"RadioPacket.getRssi not connected"
Why it is not connected?.How to solve this error.
With regards Sivasankar

Hi,
not really, you just need to use the interface CC2420Packet, that is provided
by component CC2420PacketC.
uses { interface Receive as BeaconReceive; interface CC2420Packet as
RadioPacket;}
Then, when you receive the message (in my example is a struct of type BeaconMsg)
event message_t * BeaconReceive.receive(message_t *msg, void *payload,
uint8_t len){ BeaconMsg * pointerBeacon;
int8_t rssi; if ( len == sizeBeacon ) {
pointerBeacon = (BeaconMsg*) payload;
rssi = call RadioPacket.getRssi(msg); }
}
Cheers!Sergio

Hi
Do we need to include any header file for using RSSI_VAL register.
I want to read RSSI Value.
when I am using below given line.
power=RSSI_VAL-45;//for RSSI reading,here RSSI_OFFSET is -45dBm.
It is giving error as
`RSSI_VAL' undeclared (first use in this function).
With regards
