I am using BLE_scan.ino example. Unfortunately only the first scan gives valid device serviceUUID and Name. From the second scan onward SENSOR_PRO device gives no serviceUUID the HMSoft device gives empty string as Name. It seems it is an old bug, but still no solution? Serial data from boot:

Scanning...

Its hard to do anything if i cant reproduce issue:

My peer device is android smartphone running nRF connect with advertising.
Here is scan callback:

class ScanResults: public BLEAdvertisedDeviceCallbacks {
  void onResult(BLEAdvertisedDevice device)
  {
    if(device.haveName())
    {
      Serial.printf("Device: \nTX power => %d\nRSSI => %d\n", device.getTXPower(), device.getRSSI());
      Serial.printf("Name: %s\n", device.getName().c_str());
    }
  }
};

I can only say that i am running this code on platformio with arduino + esp-idf, wifi and mqtt (code omitted).

With the original arduino BLE_scan.ino, just modified the callback as below. Still no luck. I have tried haveName() too in the callback, but then I got back nothing after the first scan.

Hardware: ESP32 Wrover Module, default settings.

class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
    void onResult(BLEAdvertisedDevice device) {
      //Serial.printf("Advertised Device: %s \n", device.toString().c_str());
      Serial.printf("Device: \nTX power => %d\nRSSI => %d\n", device.getTXPower(), device.getRSSI());
      Serial.printf("Name: %s\n", device.getName().c_str());
    }
};

Results:

Comet Blue looses its name, while SENSOR_PRO looses its UUID after the first scan. See results and full code below:

I edited the serial print format in the code to make it readable:

#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEScan.h>
#include <BLEAdvertisedDevice.h>

int scanTime = 5; //In seconds
BLEScan* pBLEScan;


class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
    void onResult(BLEAdvertisedDevice device) {
      Serial.printf("Device Name: %s, TX: %d, RSSI: %d", device.getName().c_str(), device.getTXPower(), device.getRSSI());
      if (device.haveServiceUUID()) Serial.printf(", UUID: %s", device.getServiceUUID().toString().c_str());
      Serial.println("");
    }
};


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!\n");
  pBLEScan->clearResults();   // delete results fromBLEScan buffer to release memory
  delay(2000);
}

Can I produce some debug info for you? (raw data print or something)

You can print raw advertising data for each device in onResult() callback with:
getPayload() and getPayloadLength() and Serial functions.

This way we can investigate it. Remember to print hex values.

Don't ask me how, but one version of the code worked, but only once. Then I changed one character in the code (printf format), uploaded it and failed again. Change back to the working one, fail again.

Now I changed the hardware to a completely different board: NodeMcu ESP32. Same error. I switced on verbose level debug. Does this help you? See below first and second scans. I put *** what is printed from code. The first scan ends at *** Scan done!.

What is your ESP board settings? I updated every board and library. You?

Can you try this before scan start, with value true:
https://github.com/espressif/arduino-esp32/blob/master/libraries/BLE/src/BLEScan.h#L51

Payload [33] means it does not fit advertising packet, so the other part has to be in scan response, which is scan only with active scanning (that should be enabled, and does not require any action, but worth to try, maybe esp-idf bug or settings in menuconfig).

I have tried. No change. :-( Any other what I can try?

Only thing i can say is that i never found similar issue and it is very strange.
It is obviously ignoring scan response packet which is received only during active scan.
Could you try with other esp32?

I am using 2 boards:

  1. Waveshare e-paper ESP32
  2. NodeMCU ESP32S

I am getting close... I used to use Arduino's ESP32 Wrover Module board settings in tools menu. Changing to ESP32 Dev Module solved the problem on board 1, but not on board 2. Confusing... Any idea?

I've got this warning for both of them:

Multiple libraries were found for "BLEDevice.h"
 Used: C:\Users\detre\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\BLE
Using library BLE at version 1.0.1 in folder: C:\Users\detre\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\BLE

But I do not find any other BLEDevice.h anywhere. Can be a problem?

I scanned my whole c drive. No other BLEDevice.h.

If i remember this board is using XTAL 26MHz:
NodeMCU ESP32S
Try to pick NodeMCU from boards.

I've tried NodeMCU-32S board. No change. But I've looked it up: Clock Speed: 240 Mhz.

Interestingly when I changed back to ESP Dev board, it worked. Then put in 2 Serial.println("Done") lines just to change the code, and fails again! I removed them, works. Changed back and forth, now it does not work anyome. I am really confused. Once one compilation works, even after reset and 20+ scans. But some compilation just does not work. I 've checked the Arduino comp messages. The BLE library compilation sequence is a bit different. That is all. Any idea?

I dont have explanation for that. What you can do is to see if you are not short on heap, or experiment with different boards selected in arduino.
Thats good you found it somehow related to hardware and board selected, but heap/stack shortage is last thing i can think of.
