[Tinyos-help] RSSI

[roberto pagliari]

so, if I just need to know whenever the RSSI > CCA I can get it in the two
following ways (provided that the radio is in RxMode)

    event result_t Timer.fired() {
        /*   First method   */
        uint8_t status;
        uint16_t rssi_reg;

        status = call HPLChipcon.cmd(CC2420_SNOP);
        while( (status >> RSSI_VALID) & 0x01 ) {
            status = call HPLChipcon.cmd(CC2420_SNOP);
        }
        rssi_reg = call HPLChipcon.read(CC2420_RSSI);

        /*   Second method   */
        if( TOSH_READ_RADIO_CCA_PIN() )
            // do something


is that correct?
