ScanDone signal not received in fi.w1.wpa_supplicant1.Interface

Hi Gigi,

This works. Thanks.

In my code I am getting the signal now. Based on dbus_monitor code I coded as below.

Is there any better way than handling in the while loop in the below code.

My code snippet,

main()

{

    dbus_bus_add_match(conn,buf,NULL);
     dbus_connection_flush(conn);
    dbus_connection_add_filter(conn,filter_func,NULL,NULL); //filter_func is the signal handler.

//Send Scan command to WPA_supplicant in dbus format.

Then I am waiting in a while loop till the signal handler is called and the ScanDoneHandled flag becomes true which takes out of the loop.

       while (TRUE)
        {
              dbus_connection_read_write_dispatch(conn,1000);

                if(ScanDoneHandled)
                    {
                    ScanDoneHandled = FALSE;
                    break;
                    }
        }
//Send ScanResults command.

}

Hi Johncy,

I am not an expert in dbus, but wouldn't you get the ScanDone signal in the filter_func()? Or do you want the "Scan" to be synchronous? If yes, then what you have written seems good.

Hi Gigi,

Yes I do get the ScanDone signal in the filter_func. In my code I send the scan command and waiting in the while loop untill I get the ScanDone signal. In the filter_func I set the ScanDoneHandled flag. This brings the control out of the while loop. Its like a blocking call where till the scan done signal is received I will not process any other messages. I need something like I should send a scan command and ready to receive messages from other modules. Once scandone signal is received process that and move to receive message state. For now I have moved the signal handling part as a seperate thread which receives the signal and send a message to my module. Is there any other approach?

Regards,

Johncy.
