以下是调用的方法。已经在Application初始化了。

` if (!BleManager.getInstance().isSupportBle) {
            Toast.makeText(this, "不支持蓝牙!", Toast.LENGTH_SHORT).show();
        } else {
            //支持蓝牙，打开蓝牙
            if (!BleManager.getInstance().isBlueEnable) {
                BleManager.getInstance()
                        .enableBluetooth()
            }
            BleManager.getInstance().scan(object :BleScanCallback(){
                override fun onScanning(result: BleDevice?) {

                }

                override fun onScanStarted(success: Boolean) {

                }

                override fun onScanFinished(scanResultList: MutableList<BleDevice>?) {

                }
            })`

PS：是用Kotiln写的

扫描之前，先配置一下扫描规则： BleManager.getInstance().initScanRule(scanRuleConfig)

在2.1.2版本及之前，必须先配置过滤规则再扫描；在2.1.3版本之后可以无需配置，开启默认过滤规则的扫描。
