httpGet example doesn't work

1

Hello,

I followed the documentation to compile and successfully update the httpGet app.

But the httpGet App couldn’t establish a connection after 30 seconds.

End of the output of httpGet is like below

I have an active wifi connection (client mode), I did it with this doc and I can successfully execute wget and curl commands over ssh.

What is the reason for this problem?

Thanks

If you already have data connection, there is no need to establish data connection inside the code:



COMPONENT_INIT
{
    printf("HTTP Get!\n");
#if 0
    le_timer_Ref_t timerPtr = le_timer_Create("Connection timeout timer");
    le_clk_Time_t interval = {TIMEOUT_SECS, 0};
    le_timer_SetInterval(timerPtr, interval);
    le_timer_SetHandler(timerPtr, &TimeoutHandler);
    WaitingForConnection = true;
    le_timer_Start(timerPtr);

    le_data_AddConnectionStateHandler(&ConnectionStateHandler, NULL);
    LE_INFO("Requesting connection...");
    ConnectionRef = le_data_Request();
#else

    GetUrl();
#endif
}

Thanks, you solved the problem. I had not read the codes :smile:
