15.6. Control of the module part
Each module can be controlled in a similar manner, you can find below a simple sample program
displaying the main parameters of the module and enabling you to activate the localization beacon.
using System ;
using System.Diagnostics ;
using System.Threading.Tasks ;
using Windows.UI.Xaml.Controls ;
using com.yoctopuce.YoctoAPI ;
namespace Demo
{
public class Demo : DemoBase
{
public string HubURL { get; set; }
public string Target { get; set; }
public bool Beacon { get; set; }
public override async Task < int > Run ()
{
YModule m ;
string errmsg = "" ;
if (await YAPI . RegisterHub ( HubURL ) != YAPI . SUCCESS ) {
WriteLine ( "RegisterHub error: " + errmsg );
return - 1 ;
}
m = YModule . FindModule ( Target + ".module" ); // use serial or logical name
if (await m . isOnline ()) {
if ( Beacon ) {
await m . set_beacon ( YModule . BEACON_ON );
} else {
await m . set_beacon ( YModule . BEACON_OFF );
}
WriteLine ( "serial: " + await m . get_serialNumber ());
WriteLine ( "logical name: " + await m . get_logicalName ());
WriteLine ( "luminosity: " + await m . get_luminosity ());
Write ( "beacon: " );
if (await m . get_beacon () == YModule . BEACON_ON )
WriteLine ( "ON" );
else
WriteLine ( "OFF" );
