利用多个c1101无线模块实现数据传递接力

实验设备：pc机一台，4组stc+c1101+lcd显示屏。
设想方案：
1.利用串口将pc中的数据发给1号，1号再通过无线模块将信息传递给2号，同时2号的LCD屏幕上会显示相应文字；然后2号再把数据传递给3号，同时3号的LCD屏幕上会显示相应文字；3号再把数据传递给4号，同时4号的LCD屏幕上会显示相应文字。
2.程序中编写有编号识别（只能识别并执行上一编号机发送的数据），即1号发送的数据，2、3、4号机都能接收到，但只有2号能识别并显示数据。而3号和4号机在收到数据后会因为编号不符合程序功能而不执行该功能（在LCD上显示该数据）。
遇到的问题：使用pc向1号机发送数据时，2号机能正常接收，而3号机和4号机均要发送pc发送2-5次才能接收成功。
因为初次接触无线模块，在这里请求各位大神能给予帮助。
下面是寄存器配置：

补充：接收并再传递的次序
if（halRfreceivePacker(Rxbuf,leng)）//接收数据
{
if(c_p(RxBuf))//确认接收到的数据为上一编号传递的数据
{
r_t_a_f(RxBuf);//识别并执行相应功能
delay（20）；
send_message()//发送数据给下一个编号
}
}

是我问的方法有问题么?求指点
