[vksingh225]

this.hotspot.createHotspot('MyHotspot', 'Open', '').then(resp => {
      console.log("Hotspot started ", resp);
      
        this.hotspot.startHotspot().then(resp => {
           console.log("StartHotspot  ", resp);
        }).catch(err => {
           console.log("StartHotspot error ", err);
        })    
    }).catch(err => {
      console.log("Hotspot error ", err);
    })
