用ESP32测量蓝牙连接力
用ESP32测量蓝牙连接力
提问于 2019-01-06 18:38:31
如何使用ESP32测量蓝牙连接力？我正在使用BLE的可用示例来检测连接的可能性，但我需要测量其强度。谢谢。
我使用的是：
#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);

只需在您的MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks中添加几行：
class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
void onResult(BLEAdvertisedDevice advertisedDevice) {
Serial.printf("Advertised Device: %s \n", advertisedDevice.toString().c_str
int rssi = advertisedDevice.getRSSI();
Serial.print("Rssi: ");
Serial.println(rssi);
}
