最近在调24L01的多对一通信，在调试过程中第一第二路可以调通，实现正常的无线通信，但是第三、四、五、六路就一直调不通，按资料手册上说是只要发射和接收的地址一致就可以，但是很奇怪一换到第三、四、五、六路地址通信就不行了，很是不解，想问下各位大神问题出在哪里？或者求指教24L01的多对一通信应该如何设置。
真心求教，万分感激！


附上我的程序地址码部分：
//PI   0
uchar const TX_ADDRESS[TX_ADR_WIDTH]  = {0x34,0x43,0x10,0x10,0x01};  // Define a static TX address
//PI  1
uchar const TX_ADDRESS[TX_ADR_WIDTH]  = {0xc2,0xc2,0xc2,0xc2,0xc1};// Define a static TX address
//PI 2
//uchar const TX_ADDRESS[TX_ADR_WIDTH]  =  {0xc2,0xc2,0xc2,0xc2,0xc2};// Define a static TX address
//PI 3
//uchar const TX_ADDRESS[TX_ADR_WIDTH]  = {0xc2,0xc2,0xc2,0xc2,0xc3};// Define a static TX address
//PI 4
//uchar const TX_ADDRESS[TX_ADR_WIDTH]  = {0xc2,0xc2,0xc2,0xc2,0xc4};// Define a static TX address
//PI 5
//uchar const TX_ADDRESS[TX_ADR_WIDTH]  = {0xc2,0xc2,0xc2,0xc2,0xc5};// Define a static TX address
