CC1101 radio problem

Other Parts Discussed in Thread: CC1101

Hello,

 I am implementing TDMA protocol with CC1101 radio. The radio always receives unexpected packet and occurs GDO interrupt when no radio sends packets. Do you know how to prevent the unexpected interrupt?

  • 哪个引脚?看datasheet的61页General Purpose / Test Output Control Pins,确认GDOx_CFG都设的什么值。你也可以使用Smartstudio来观测一下(处于接收状态),你周围空间是否有这样的干扰。

  • 两个管教寄存器设的都是0x06,检测sync word 下降沿中断。但是 在发送端没有发送任何数据包的时候,接收端也会收到一些不正常的数据包,或者发送端发送一次数据包,接收端接受了,然后隔几ms或者几秒会又接受一次。理论上,接收端在接受数据包之前都会进行sync word检测,怎么才能降低这种干扰呢
