cc1110 接收距离，软件能调哪些参数？

SYNC1 = 0x2D;
SYNC0 = 0xD4;
PKTLEN = 0x0C; // Packet length.
PKTCTRL1 = 0x14; // Packet automation control.
PKTCTRL0 = 0x00; // Packet automation control.
ADDR = 0x00; // Device address.
CHANNR = 0x00; // Channel number.

FSCTRL1 = 0x08; // Frequency synthesizer control.
FSCTRL0 = 0x00; // Frequency synthesizer control.

FREQ2 = 0x21; // Frequency control word, high byte.
FREQ1 = 0x65; // Frequency control word, middle byte.
FREQ0 = 0x6A; // Frequency control word, low byte.

MDMCFG4 = 0x66; // Modem configuration.
MDMCFG3 = 0x83; // Modem configuration.
MDMCFG2 = 0x02; // Modem configuration.
MDMCFG1 = 0x12; // Modem configuration.
MDMCFG0 = 0xF8; // Modem configuration.

DEVIATN = 0x51; // Modem deviation setting (when FSK modulation is enabled).

MCSM2 = 0x07; // Main Radio Control State Machine configuration.
MCSM1 = 0x1F; // Main Radio Control State Machine configuration.
MCSM0 = 0x18; // Main Radio Control State Machine configuration.

FOCCFG = 0x1D; // Frequency Offset Compensation Configuration.

BSCFG = 0x1C; // Bit synchronization Configuration.

AGCCTRL2 = 0xC7; // AGC control.
AGCCTRL1 = 0x00; // AGC control.
AGCCTRL0 = 0xB2; // AGC control.

FREND1 = 0xB6; // Front end RX configuration.
FREND0 = 0x10; // Front end RX configuration.

FSCAL3 = 0xE9; // Frequency synthesizer calibration.
FSCAL2 = 0x2A; // Frequency synthesizer calibration.
FSCAL1 = 0x00; // Frequency synthesizer calibration.
FSCAL0 = 0x1F; // Frequency synthesizer calibration.

TEST2 = 0x88; // Various test settings.
TEST1 = 0x31; // Various test settings.
TEST0 = 0x09; // Various test settings.

PA_TABLE0 = 0x50; // PA output power setting.

 这类的粘贴可读性太差啦。。。。回复率一般很低的。

建议还不如把smartRF studio的截图发上来，然后说明你具体要干嘛。。。。

想调整rf接受信号的强度。需要设置哪些寄存器可以改善？

"接受信号的强度", 这个是物理规则，你如果从smartRF sudio默认导出配置应该已经是最优了。

可以看看通过改善天线性能和增加外部LNA来实现。

如果是868频段的话，可以看看TI的CC1190/cc1192器件。
