c# - Async HFP discovery with 32feet -

-

i in process of writing bluetooth scanner monitor traffic outside house. understand car bt devices have 3 states, visible (always on), limited, , invisible.

i'm using asynchronous device discovery bluesoleil drivers, , class 1 bluetooth dongle.

my problem device name , device class isn't being discovered. discovering device address, , range, not name of device.

i have tried using system.threading.thread.sleep(1000) calling device.refresh() no avail.

it picking name of few things in range, tvs, , fitbit flexes, it's important can find name , cod of car bluetooth devices, not mac address , range.

  public void setuplistener()     {         var client = new bluetoothclient();         var component = new bluetoothcomponent(client);         component.discoverdevicesasync(255, false, false, true, false, null);         component.discoverdevicesprogress += component_discoverdevicesprogress;         component.discoverdevicescomplete += component_discoverdevicescomplete;     }      void component_discoverdevicescomplete(object sender, discoverdeviceseventargs e)     {         setuplistener();     }      void component_discoverdevicesprogress(object sender, discoverdeviceseventargs e)     {         bluetoothdeviceinfo[] availabledevices = e.devices bluetoothdeviceinfo[];         foreach (bluetoothdeviceinfo device in availabledevices)         {             device.refresh();              var name = device.devicename; // returns mac address             var cod = device.classofdevice.device; // returns miscellaneous         }     }

the application i've built simple wpf form dumps found devices datagrid (which i've removed code simplicity's sake). results like.

when sit outside closer road, picking more , more devices cars drive by, can't tell type of device it's detecting.

datagrid of results

any appreciated.
