First initialize the Bluetooth module :

                    uni.openBluetoothAdapter()

  Then decide whether to turn on Bluetooth 

                        /*  Determine whether to turn on Bluetooth  */
						uni.getBluetoothAdapterState({
						  success(res) {
                           // If res.avaliable==false  It means that Bluetooth is not turned on   On the contrary 
						   if(res.available==false){
							   uni.$u.toast(" Please turn on Bluetooth ")
							   return
						   }else{
                               // This is my business 
							   /*  Set the protection mode  */
							   this.setTerminalMode({
							   	workMode: 1
							   }, 0)
						   }
						  }
						})
