Реагировать на нативного рекламодателя, как удалить список устройств при потере соединения (например, при слишком большом расстоянии между устройствами)

Question

Всем привет! Вот код из https://github.com/mplaza/react-native-ble-advertiser, они показывают мне, как обнаруживать новые устройства, но не показывают, как удалить, когда устройства go далеко. Кто-нибудь может мне помочь! Я новичок ie в реакции на родной.

addDevice(_uuid, _name, _rssi, _date) {
      let index = -1;
      for(let i=0; i< this.state.devicesFound.length; i++){
        if (this.state.devicesFound[i].uuid == _uuid) {
          index = i;
        }
      }
      if (index<0) {
        let dev = {uuid:_uuid, name:_name, rssi:_rssi, start:_date, end:_date};
        this.setState({
          devicesFound: update(this.state.devicesFound, 
            {$push: [dev]}
          )
        });
      } else {
        //let dev = this.state.devicesFound[index];
        //const newList = this.state.devicesFound.splice(index, 1);
        const itemIndex = index;
        this.setState({
          devicesFound: update(this.state.devicesFound, 
            {[itemIndex]: {end: {$set: _date}, rssi: {$set: _rssi || this.state.devicesFound[itemIndex].rssi }}}
          )
        });
      }
    }
start() {
      console.log(this.state.uuid, "Registering Listener");
      const eventEmitter = new NativeEventEmitter(NativeModules.BLEAdvertiser);

      this.onDeviceFound = eventEmitter.addListener('onDeviceFound', (event) => {
        //console.log('onDeviceFound', event);
        if (event.serviceUuids) {
          for(let i=0; i< event.serviceUuids.length; i++){
            if (event.serviceUuids[i] && event.serviceUuids[i].endsWith('00'))
              this.addDevice(event.serviceUuids[i], event.deviceName, event.deviceAddress, event.rssi, new Date())   
          }
        }
      });

      console.log(this.state.uuid, "Starting Advertising");
      BLEAdvertiser.broadcast(this.state.uuid, MANUF_DATA, {
        advertiseMode: BLEAdvertiser.ADVERTISE_MODE_BALANCED, 
        txPowerLevel: BLEAdvertiser.ADVERTISE_TX_POWER_MEDIUM, 
        connectable: false, 
        includeDeviceName: false, includeTxPowerLevel: false })
        .then(sucess => console.log(this.state.uuid, "Adv Successful", sucess))
        .catch(error => console.log(this.state.uuid, "Adv Error", error));
      
      console.log(this.state.uuid, "Starting Scanner");
      BLEAdvertiser.scan(MANUF_DATA, {scanMode: BLEAdvertiser.SCAN_MODE_LOW_LATENCY})
        .then(sucess => console.log(this.state.uuid, "Scan Successful", sucess))
        .catch(error => console.log(this.state.uuid, "Scan Error", error));

      this.setState({
        isLogging: true,
      });
    }
