CC1350最高传输速率 配置

Other Parts Discussed in Thread: CC1350

您好 最近在用贵公司的CC1350 Launchpad做无线通信开发，通过rfPacketErrorRate例程实现了sub-1G频段的高速率点对点通信，但是发现最高信息速度只能到达2Mpbs，所以想咨询下fPacketErrorRate例程HSM模式最高只支持2Mbps（代码标注为4Mbps）吗？如果想再提升速率该怎么配置，有没有参考。我查阅了相关的芯片资料和SDK说明文档，感觉是要配置RF core firmware patches（CPE、MEC、RFE），但没有找到相关的配置说明和方法。望解答，谢谢！

    Test cases are provided for the following RF modes:

    Custom : Custom settings to be exported from SmartRF Studio to the smartrf_settings.c file

    2-GFSK : Gaussian frequency shift keying with binary symbols, 50 kBit/s for all launchpads, 250 KBits/s for the CC2640R2

    GFSK 200K : Gaussian frequency shift keying with binary symbols, 200 kBit/s IEEE 802.15.4g for all CC13x2 launchpads

    GFSK 100K : Gaussian frequency shift keying with binary symbols, 100 kBit/s (CC2640R2 only)

    GFSK 250K : Gaussian frequency shift keying with binary symbols, 250 kBit/s (CC2640R2 only)

    LR Mode : Legacy Long Range (625 bps)

    OOK : On-off keying

    HS Mode : High-speed mode with up to 4 MBit/s

    SL LR : SimpleLink Long Rang (5 kbps)

    BLE : Bluetooth Low Energy (CC135X, CC2640R2 only)

    BLE5 : Bluetooth Low Energy 5 (CC1352, CC2640R2 only)

    Note that - HSM and OOK are not supported on the CC1310-CC1190, CC1350 (433 MHz), CC1352 (R1/P1/P-2/P-4) or CC2640R2 Launchpads - Legacy Long Range Mode (LRM) is not supported on the CC1352(R1/P1/P-2/P-4). - For the GFSK 200K mode, if transmitting from Smart RF Studio set the PSDU octet transmission order to MSbit First

    最高到4Mbps，请注意如上的要求

    谢谢回复，
    （1）请问 CC1350 (433 MHz)是指一款特定的CC1350 Launchpads还是指CC1350 Launchpads工作在433MHz频点？
    （2）我用CC1350 Launchpads实现rfPacketErrorRate例程时的工作频点为868MHz，实际操作是payload长度置为最大254bytes，然后通过trigger.starttime控制发送间隔，将发送间隔下调至1ms时信息速率达到2Mbps，但是再将发送间隔下调至小于1ms时，似乎发送间隔没有改变，信息速率仍然是2Mbps左右，接收端也能正常接收数据，统计的信息速率仍然为2Mbps左右。所有不太确定是RAT设置不正确，还是信道最大带宽就是2Mbps了。

    是指CC1350 Launchpads工作在433MHz频点，CC1350支持多频段
