用smartRF studio 7对寄存器进行配置：---------------------------------------------------------------------------------------------------
配置1

base frequency	channel number	channel spacing	carrier frequency	Xtal frequency
432.999817MHz	0	198.760986KHz	432.999817KHz	26MHz
Date rate	RX filter BW	Modulation format	Deviation	TX power
249.939KBaud	541.666667	GFSK	126.953125KHz	10dBm

-------------------------------------------------------------------------------------------------------
配置2

base frequency	channel number	channel spacing	carrier frequency	Xtal frequency
433.499695MHz	0	199.951172KHz	433.499695KHz	26MHz
Date rate	RX filter BW	Modulation format	Deviation	TX power
249.939KBaud	541.666667	GFSK	126.953125KHz	10dBm

将从smartR studio7中得到的寄存器配置分别copy到mrfi>smart_CC1110.h中编译和下载，得到的结果却不同：
配置1：两个ED之间建立不起连接，更别谈通信；
配置2：两个ED之间可以建立连接并且正常通信。
的确有一些奇怪，配置几乎没有差别，实验结果却大不相同。看来，射频配置很重要啊
有没有遇到同样问题的朋友呢？可以一起讨论一下
