本文介绍了如何在FireBeetle-ESP32上使用Arduino IDE读取蓝牙设备的RSSI值。通过BLEDevice库和BLEAdvertisedDevice回调函数，用户可以在扫描到的蓝牙设备列表中获取每个设备的RSSI值。具体步骤包括初始化BLE设备、设置扫描参数、定义回调函数并在其中添加读取RSSI值的代码。通过这些步骤，用户可以轻松实现蓝牙设备信号强度的读取，为项目提供更准确的数据支持。

最近一直在找方法读取ESP32蓝牙的RSSI，一直没有结果请求各位帮忙。在demo中要加什么才能读取RSSI。
#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEScan.h>
#include <BLEAdvertisedDevice.h>

int scanTime = 30; //In seconds

class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
void onResult(BLEAdvertisedDevice advertisedDevice) {
   Serial.printf("Advertised Device: %s \n", advertisedDevice.toString().c_str());
}
};

void setup() {
  Serial.begin(115200);
  Serial.println("Scanning...");

  BLEDevice::init("");
  BLEScan* pBLEScan = BLEDevice::getScan(); //create new scan
  pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks());
  pBLEScan->setActiveScan(true); //active scan uses more power, but get results faster
  BLEScanResults foundDevices = pBLEScan->start(scanTime);
  Serial.print("Devices found: ");
  Serial.println(foundDevices.getCount());
  Serial.println("Scan done!");
}

void loop() {
// put your main code here, to run repeatedly:
  delay(2000);
}
