TI中文支持网工程师你好！
CC1310，一块板一直发，一块板一直收；
error_rate的基础上进行修改；
433MHz，4fsk, 1Mbps;
射频线缆直连的情况下，丢包率为1/100000，请问是否正常呢？
每次发送的间隔比较长为30ms，请问丢包的原因是什么呢？有无优化的办法？
谢谢！
lin jqi：
更正一下：丢包率应该是0.3%。谢谢！

这个是测试的，正式发布版中没有4fsk, 1Mbps，手册中没有具体的数据
之前发过915M的，你可以参考下
500kbps GFSK -97 1% BER, 1243 RX BW, 175KHz deviation
1Mbps BLE PHY -95 1% BER, 250KHz deviation, 2GFSK
1.5Mbps 4FSK -94 1% BER, 4FSK, Outer deviation 450KHz
4Mbps 8FSK -82 1% BER, 8FSK

感谢回复！
看来误包率是接近的；但提到的1.5Mbps 4FSk总是不能达到，1Mbps倒是可以的，两组参数如下，麻烦看看1.5Mbps的是否有错，谢谢！

433M 1.5Mbps偏差比较大，建议用1Mbps：e2e.ti.com/…/2375692
