在非 MMI task, socket 回调函数执行不...

[wangou42]

在 MMI task，程序一切正常，可以 send, recv。
在我自己写的一个 task 内，可以 connect，之后，遇到 SOC_WOULDBLOCK 并注册回调函数，回调函数一直没有响应。自定义的 task 没有收到 MSG_ID_APP_SOC_NOTIFY_IND 消息，却收到了 MSG_ID_APP_SOC_BEARER_INFO_IND 消息。
有没有谁遇到类似的问题啊？我是新手，请多多指教。


代码是在网上搜索的获取天气的：

unsigned char weather_URL[]={
"GET http://61.135.159.21/cgi-bin/weather?0755 HTTP/1.1\\r\\n"
"Host: 10.0.0.172:80\\r\\nUser-Agent: */*\\r\\nAccept:*/*\\r\\n"

在我自己的 task 内，get_network_time_socket_notify 永远不会被调用，在 MMI task 内就没有问题。

不知道在 task 主函数里是不是需要相应处理？

[wangou42]

socket 似乎只能在 MMI 线程里面跑啊

[xinyuiancai]

好像都没人来看的....

[xiaokui_hyz]

有没有执行这get_network_time_socket_notify(void *msg_ptr）函数呀
