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!

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
