Bluetooth Low Energy (BLE) does not work properly with ESP32S3

A2lm24 · November 18, 2023, 6:51pm

When I try to use the ESP32-BLE-MIDI library sample sketch on my XIAO ESP32S3, I can pair it, but it keeps connecting and disconnecting randomly. Moreover, no notes are sent.

The following is the message output to the serial monitor ↓

I’m translating from Japanese, so there may be some sentence errors, sorry.

The BLE server/client code listed here also did not execute correctly.

//Server Code
#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEServer.h>

#define SERVICE_UUID        "4fafc201-1fb5-459e-8fcc-c5c9c331914b"
#define CHARACTERISTIC_UUID "beb5483e-36e1-4688-b7f5-ea07361b26a8"

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");

  BLEDevice::init("XIAO_ESP32S3");
  BLEServer *pServer = BLEDevice::createServer();
  BLEService *pService = pServer->createService(SERVICE_UUID);
  BLECharacteristic *pCharacteristic = pService->createCharacteristic(
                                         CHARACTERISTIC_UUID,
                                         BLECharacteristic::PROPERTY_READ |
                                         BLECharacteristic::PROPERTY_WRITE
                                       );

  pCharacteristic->setValue("Hello World");
  pService->start();
  // BLEAdvertising *pAdvertising = pServer->getAdvertising();  // this still is working for backward compatibility
  BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();
  pAdvertising->addServiceUUID(SERVICE_UUID);
  pAdvertising->setScanResponse(true);
  pAdvertising->setMinPreferred(0x06);  // functions that help with iPhone connections issue
  pAdvertising->setMinPreferred(0x12);
  BLEDevice::startAdvertising();
  Serial.println("Characteristic defined! Now you can read it in your phone!");
}

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

I used the nRF Connect app on Android, but could not connect.
Below is the statement output to the serial monitor and a screenshot of the nRF Connect app.

Starting BLE work!
Characteristic defined! Now you can read it in your phone!

Hi there,
I was able to download your code and compile and run it no issue’s
I could connect with Nrf Desktop & mobile app.
Both allowed me to connect and read the Hello world Text.

I suspect it’s your device or compiled LIB’s
Here’s some output

Thank you for your research!
I have been operating the nRF Connect app incorrectly, and I was able to check Hello World here as well!
However, I cannot pair it.
