-(void)peripheral:(CBPeripheral *)peripheral didUpdateNotificationStateForCharacteristic:(CBCharacteristic *)characteristic error:(NSError *)error{

    if (error) {

        JWLog(@"%@",[error localizedDescription]);

        return;

    }

    JWLog(@"updateNotification");

该代理抛出错误：invalid handle error

解决方法：将蓝牙重新启动，错误消失，连接正常
