issue getting producer data only once

[tekinyasin02]

Hi

I apply BleScan with ESP32. Finds the other esp32. however, it does not receive manufacturer data for the second time. what would be the reason

My code

int scanTime = 10; //In seconds BLEScan* pBLEScan;

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(""); pBLEScan = BLEDevice::getScan(); //create new scan pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks()); pBLEScan->setActiveScan(true); //active scan uses more power, but get results faster pBLEScan->setInterval(100); pBLEScan->setWindow(99); // less or equal setInterval value }

void loop() { // put your main code here, to run repeatedly: BLEScanResults foundDevices = pBLEScan->start(scanTime, false); Serial.print("Devices found: "); Serial.println(foundDevices.getCount()); Serial.println("Scan done!"); pBLEScan->clearResults(); // delete results fromBLEScan buffer to release memory delay(2000); }`
