Title: read "Devices[I].Address" is normal, but read "aName" is empty the contents ?
Post by: parparpar on January 05, 2010, 11:10:30 AM

aName : Without name 

I use Delphi7\WCL671\VCL\demo\Delphi\BluetoothOPP example of a successful compile run.
In the run to the "Res:= Devices.GetName(Radio, aName);" After this line, read "Devices.Address" is normal, but it reads "aName" is empty the contents  ???, "Res " is WCL_E_SUCCESS

Why?

Thanks

Thank you for your reply !

        while Cnt < 5 do begin
          Sleep(100);            //    So?         
          Res := Devices.GetName(Radio, aName);
          if (aName <> '') or (Res <> WCL_E_SUCCESS) then Break;
          Inc(Cnt);
        end;
