char buffern[500];
TCPSocket *tcpsocketn;
rtos::Thread tcp_recv_thread,i2s_rx_thread;

void rx_thread(void)
{
while (true) {

printf("录音中..\r\n");
}
}
void tcp_recv(TCPSocket *tcpsockets,char *buffer, int Len)
{ uint16_t size=1;
int ret;

while(true){

   do {

   if (buffer <= 0) {

   break;
   }

   printf("TCP send len is %s !\r\n",buffer);

   }while (size > 0);
   }

}
void tcp_connect(TCPSocket *tcpsockets,char *addressn, uint16_t port,NetworkInterface *net_iface)
{ int ret,size;
//tcpsocketn =new TCPSocket(net_iface);
SocketAddress address(addressn,port);

if (!address) {
   printf("地址错误\r\n");
   return;
}
ret = (int)tcpsockets->connect(address);
if(ret != 0){
   printf("连接错误 = %d\r\n", ret);
   return;
}
printf("连接成功！%d\r\n", ret);
}

void tcp_send(TCPSocket *tcpsockets,char *buffern,uint16_t Len)
{
int size=0;
size = tcpsockets->send("kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk",strlen("kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk"));// - 1
if (size <= 0) {

}else{

}
}
int main()
{

tcpsocketn =new TCPSocket(&wifi);
tcp_connect(tcpsocketn,"192.168.1.104",8090,&wifi);
tcp_send(tcpsocketn,"hhhhhhhhhh",500);
i2s_rx_thread.start(rx_thread);
tcp_recv_thread.start(tcp_recv,tcpsocketn,buffern,500);

while (true) {
aplay_wav("/sdc/mydir/14_00.wav");

}

rtos::Thread::wait(osWaitForever);

}

以上
tcp_recv_thread.start(tcp_recv,tcpsocketn,buffern,500);这行代码出错

"TESTS/TARGET_RDA/tcp/main.cpp", line 207: Error: #304: no instance of overload
ed function "rtos::Thread::start" matches the argument list
argument types are: (void (TCPSocket *, char *, int), TCPSocket *, c

"TESTS/TARGET_RDA/tcp/main.cpp", line 221: Warning: #111-D: statement is unreac

如果这样就i2s_rx_thread.start(rx_thread);就没出错，大神们这个是什么问题，

i2s_rx_thread.start(rx_thread);
tcp_recv_thread.start(tcp_recv,tcpsocketn,buffern,500);

这两个函数定义分别是什么？

lilo 说：

i2s_rx_thread.start(rx_thread);
tcp_recv_thread.start(tcp_recv,tcpsocketn,buffern,500);

这两个函数定义分别是什么？

上面两个代码都是启动一个线程，rx_thread是自己写没带参数的函数
，tcp_recv是自己写的带三个参数的函数

把 start 函数的定义贴出来，肯定是你传参数的类型不匹配。

晕哥,start 函数

osStatus Thread::start(Callback<void()> task) {

.start不能传有参数的函数么

Thread::start(Callback<void()> task)

很明显只能传一个参数, 你传那么多肯定会编译错误，你看下别的demo怎么传其他参数，比如pthread创建线程的时候可以传一个指针进去。

晕哥，demo没有看到有传其他参数，这是一个RDA5981的sdk,不知怎么搞个
指针进去传进去

RDA5981 SDK 哪里有下载？有空我帮你看下.
