    逻机可以参考如下代码，里面已经有考虑如何获取RSSI。代码里搜rxi.rssi， 里面也有对rssi的校准。参考如下接收函数

    http://www.ti.com/lit/zip/swrc135

    uint8 basicRfReceive(uint8* pRxData, uint8 len, int16* pRssi)
    {
    // Accessing shared variables -> this is a critical region
    // Critical region start
    halIntOff();
    memcpy(pRxData, rxi.pPayload, min(rxi.length, len));
    if(pRssi != NULL) {
    if(rxi.rssi < 128){
    *pRssi = rxi.rssi - halRfGetRssiOffset();
    }
    else{
    *pRssi = (rxi.rssi - 256) - halRfGetRssiOffset();
    }
    }
    rxi.isReady = FALSE;
    halIntOn();

    // Critical region end

    return min(rxi.length, len);
    }

    uint8 basicRfReceive(uint8* pRxData, uint8 len, int16* pRssi)
    {
    // Accessing shared variables -> this is a critical region
    // Critical region start
    halIntOff();
    memcpy(pRxData, rxi.pPayload, min(rxi.length, len));
    if(pRssi != NULL) {
    if(rxi.rssi < 128){
    *pRssi = rxi.rssi - halRfGetRssiOffset();
    }
    else{
    *pRssi = (rxi.rssi - 256) - halRfGetRssiOffset();
    }
    }
    rxi.isReady = FALSE;
    halIntOn();

    // Critical region end

    return min(rxi.length, len);
    }
