The problem here is in p_wifi.cc in stage. This only copies the mac address information into the wifi structure

  pdata.links_count = sdata->neighbours->len;
  pdata.links = new player_wifi_link_t[pdata.links_count];
  assert(pdata.links);
  memset(pdata.links,0,sizeof(player_wifi_link_t)*pdata.links_count);
  for(guint i=0;i<sdata->neighbours->len;i++)
  {
    stg_wifi_sample_t samp = g_array_index(sdata->neighbours,
                                           stg_wifi_sample_t, i);
    memcpy(pdata.links[i].mac,samp.mac,sizeof(pdata.links[i].mac));
    pdata.links[i].mac_count = sizeof(pdata.links[i].mac);
    //printf("%f\n", samp.db);
  }

  // Publish it
  this->driver->Publish(this->addr,

You would need to update this method in order to see the rest of the data on the client side. If you do fix this please submit a patch to the tracker.

Hi all,
i'm still trying to investigate my problem with Wifi models in stage ...
I'm using Stage 2.1.1 & Player 2.1.2 under Mac OS X. I'm using the
"simple" wifi model under stage.
When i print the various values of links in model_wifi.cc file,
everything is ok. For example, i got the default freq 2450 value.
But on the other side, in my player client program, all the value are
zeroed except the mac adress.
Something happens during the transmission of wifi informations between
the simulation engine and the client ...

The following program always print 0 for signal quality and freq :

#include <iostream>
#include <libplayerc++/playerc++.h>

int
main(int argc, char *argv[])
{
 using namespace PlayerCc;

 PlayerClient    robot("localhost");
 Position2dProxy pp(&robot,0);
 WiFiProxy       wp(&robot,0);

 for (int j=0; j<1000; j++) {
   robot.Read();
   std::cout << wp << std::endl;
   for (int i=0; i<wp.GetLinkCount(); i++) {
     std::cout << "Signal Quality = " << wp.GetLinkQuality(i) <<std::endl;
     std::cout << "Signal Freq = " << wp.GetLinkFreq(i) << std::endl;
     std::cout << "IP = " << wp.GetLinkIP(i) << std::endl;
   }
 }
}

Best regards,
