Ionic framework 获取壁橱设备

是否有任何方法可以获取离手机最近的设备，或按最接近的设备排序的可用设备列表

比如：

...

ble: BluetoothLE
...
const params: ScanParams = {
  services: [],
  allowDuplicates: false,
  scanMode: this.ble.SCAN_MODE_LOW_LATENCY, //Something to do here maybe?
  matchMode: this.ble.MATCH_NUM_MAX_ADVERTISEMENT,
  matchNum: this.ble.MATCH_NUM_ONE_ADVERTISEMENT
};
this.ble.startScan(params).subscribe(device=>{
   //Something to do here maybe?
})

我认为最好的办法就是使用信号强度（RSSI）。但信号强度可能受到障碍物的影响，而不仅仅是距离
