Esp32 bluetooh error

diegobeltran · March 1, 2023, 1:48am

Good day.
I have the following error when trying to connect to bluetooth from a cell phone.

Guru Meditation Error: Core 0 panic'ed (IntegerDivideByZero). Exception was unhandled.
Core 0 register dump:

ELF file SHA256: 0000000000000000

The following is the code that I am using.

//This example code is in the Public Domain (or CC0 licensed, at your option.)
//By Evandro Copercini - 2018
//
//This example creates a bridge between Serial and Classical Bluetooth (SPP)
//and also demonstrate that SerialBT have the same functionalities of a normal Serial

`#include "BluetoothSerial.h"

#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run make menuconfig to and enable it
#endif

BluetoothSerial SerialBT;

void setup() {
Serial.begin(115200);
SerialBT.begin("ESP32test"); //Bluetooth device name
Serial.println("The device started, now you can pair it with bluetooth!");
delay(20);
}

void loop() {
if (Serial.available()) {
SerialBT.write(Serial.read());
}
if (SerialBT.available()) {
Serial.write(SerialBT.read());
}

}`

Could someone please tell me how to solve it, thanks.

Please explain more about what you are doing?
At what point do you see the error?

Your code compiles fine for my ESP32, my Android phone can see and pair with the ESP32. The app I use is Kai Morich's Serial Bluetooth Terminal and it can connect and communicate with the esp32.

Hello cattle dog. Thank you so much for taking the time to respond. Indeed it compiles correctly and is visible to my android cell phone, the problem persists when I try to pair from the android mobile it is impossible, when I look in real time on the serial monitor I see the error that I published in the first post.

There is nothing in your code to print
"Pairing Success" which is seen after "The device started, now you can pair it with bluetooth!"

Are you indeed posting the complete code you are running.

When I pair with my phone at that point in the code, I see no message about success.

What version of the esp core are you using? What is the version of BluetoothSerial.h being used?

I recommend that you up date the esp core to the latest in the board manager.

If that doesn't fix the issue, enable verbose output during compile and upload and post the complete messages. Do not post a picture, put just post the text.

hello cattledog. Thank you very much for the help you give me.

I have followed your recommendations.

I enable the build alerts and in them I see the version of the BluetoothSerial library

"Usando librería BluetoothSerial con versión 1.0 en la carpeta:"

Regarding the kernel version, I don't know where I can identify it or how I can update it, I have searched the internet for how to update it, but I don't understand if there is any procedure or guide.

The following are the messages at compile time:

In the serial monitor I have the following:

"The device started, now you can pair it with bluetooth!"

When I try to pair from the "bluetooth serial" app, the serial monitor automatically shows me the following:

And in the SerialBluetooth app it shows me the following:

"Connection failed: read failed, socket might closed or timeout, read ret: -1"

Just to confirm, the code used is the one provided by the arduino IDE in its serialToSerialBT example:

#include "BluetoothSerial.h"

#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run make menuconfig to and enable it
#endif

BluetoothSerial SerialBT;

void setup() {
Serial.begin(115200);
SerialBT.begin("ESP32test"); //Bluetooth device name
Serial.println("The device started, now you can pair it with bluetooth!");
}

void loop() {
if (Serial.available()) {
SerialBT.write(Serial.read());
}
if (SerialBT.available()) {
Serial.write(SerialBT.read());
}
delay(20);
}

If you look through the report carefully you see at the very beginning.

Using board 'esp32doit-devkit-v1' from platform in folder: C:\Users\User\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6
Using core 'esp32' from platform in folder: C:\Users\User\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6

Then if you look carefully through the report foe versions od BluetoothSerial.h you find

ResolveLibrary(BluetoothSerial.h)
-> Candidatos: [BluetoothSerial@1.0]

Usando librería BluetoothSerial con versión 1.0 en la carpeta: C:\Users\User\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6\libraries\BluetoothSerial

The current version of the ESP32 arduino core is 2.07 and it includes BluetoothSerial.h version 2.0.

Use the boards manager of the IDE to upgrade to the latest core version.

diegobeltran · March 1, 2023, 9:08pm

Thank you very much in advance for your help.

I have followed your recommendations and I have already successfully updated the core.

Using board 'esp32doit-devkit-v1' from platform in folder: C:\Users\User\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.7

I used one of the examples that the IDE gives me again.

//This example code is in the Public Domain (or CC0 licensed, at your option.)
//By Evandro Copercini - 2018
//
//This example creates a bridge between Serial and Classical Bluetooth (SPP)
//and also demonstrate that SerialBT have the same functionalities of a normal Serial

#include "BluetoothSerial.h"

//#define USE_PIN // Uncomment this to use PIN during pairing. The pin is specified on the line below
const char *pin = "1234"; // Change this to more secure PIN.

String device_name = "ESP32-BT-Slave";

#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run `make menuconfig` to and enable it
#endif

#if !defined(CONFIG_BT_SPP_ENABLED)
#error Serial Bluetooth not available or not enabled. It is only available for the ESP32 chip.
#endif

BluetoothSerial SerialBT;

void setup() {
  Serial.begin(115200);
  SerialBT.begin(device_name); //Bluetooth device name
  Serial.printf("The device with name \"%s\" is started.\nNow you can pair it with Bluetooth!\n", device_name.c_str());
  //Serial.printf("The device with name \"%s\" and MAC address %s is started.\nNow you can pair it with Bluetooth!\n", device_name.c_str(), SerialBT.getMacString()); // Use this after the MAC method is implemented
  #ifdef USE_PIN
    SerialBT.setPin(pin);
    Serial.println("Using PIN");
  #endif
}

void loop() {
  if (Serial.available()) {
    SerialBT.write(Serial.read());
  }
  if (SerialBT.available()) {
    Serial.write(SerialBT.read());
  }
  delay(20);
}

I keep getting the same error when I try to connect to the "Serial Bluetooth" app, resulting in the following error on the output monitor.

The device with name "ESP32-BT-Slave" is started.
Now you can pair it with Bluetooth!

Is it possible that the mobile phone is related to the error?

cattledog · March 1, 2023, 9:40pm

Good job on the update.

Possibly. It's certainly not the issue with the sketch.

What phone and Android Version are you using? Do you or a friend have another phone to try?

ESP32-D0WD-V3 (revision 3)
What board selection have you made for this chip.

diegobeltran · March 1, 2023, 10:25pm

Greetings.

The android version is 11.

I'm going to try to do a test on another mobile device.

Within the arduino ID at the top, select the option "DOIT ESP32 DEVKIT V1", in addition to this, on the back of the esp32 it has "ESP 23 DEVKIT V1" printed.

Thank you in advance for the time you invest in supporting me.
