cc1200 与cc430之间的通信问题
请问个问题:
我现在有CC430,配置的速率为250kbps,采用MSK调制。
现在我想用CC1200与之通信,按用户手册的说的MSK配置方法,速率配为250KBPS,调制方式为2FSK,频偏为62.5KHZ,但配置完后就是无法通信,这要如何解决?
注意:我经过试验测试,速率,频率等参数都是正确的,不知到还有什么地方遗漏的? 我还将CC430的调试方式改为2FSK后,就可以和CC1200通信了,但改回MSK后,又不能通信了。
估计还是配置没弄对吧。Frequency Deviation 设置对了吗?要用 MSK 需要收发两端都配置为MSK。调制方式可以试试2GFSK。
5.2.3 Minimum Shift Keying
When using MSK , the complete transmission (preamble, sync word, and payload) will be MSK modulated. MSK modulation is configured by MODCFG_DEV_E.MOD_FORMAT set to 2-(G)FSK modulation and frequency deviation set to ¼ of symbol rate. Then phase shifts are performed with a constant transition time. Table 14 shows what the frequency deviation should be programmed to for different symbol rates to achieve a modulation index ~0.5.
