CC1310丢包率确认

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!

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
