CC2530 控制输出功率的寄存器是 TXPOWER:
推荐功率设置：
协议栈默认的设置是 0xd5,为了扩展信号传输的距离，我把TXPOWER寄存器值改为0xf5, 此时输出功率为4.5dBm.在mac_radio.c文件，做了如下修改：
void macRadioSetTxPower(uint8 txPower)
{
halIntState_t s; /* if the selected dBm is out of range, use the closest available */
if (txPower > MAC_RADIO_TX_POWER_MAX_DBM)
{
txPower = MAC_RADIO_TX_POWER_MAX_DBM;
} /*
* Set the global variable reqTxPower. This variable is referenced
* by the function macRadioUpdateTxPower() to write the radio register.
*
* A lookup table is used to translate the power level to the register
* value.
*/
HAL_ENTER_CRITICAL_SECTION(s);
reqTxPower = macRadioDefsTxPowerTable[txPower];
HAL_EXIT_CRITICAL_SECTION(s); /* update the radio power setting */
//************** 自己修改 *******
reqTxPower = 0xF5;
//*******************************
macRadioUpdateTxPower();
