ESP32 with Matrix, IR and BLE: Guru Meditation Error

[StevenCellist]

Hardware:

Board: ESP32 Dev Module Core Installation/update date: most recent IDE name: Arduino IDE Flash Frequency: 80Mhz PSRAM enabled: no Upload Speed: 115200 Computer OS: Windows 10

Description:

I want to add BLE to my ESP32. If a device connects, a variable is changed so that the matrix displays certain texts etc. But once I added the BLE coding, my ESP went on a Guru Meditation Error, because Core 1 panic'ed. I removed all excess coding but still it won't work. Only once I comment out the BLE descriptors in the void setup(), it runs. How can I change my code so it won't crash?

Sketch:

#include <Adafruit_GFX.h>   // Core graphics library
#include <P3RGB64x32MatrixPanel.h>
#include <IRremote.h> //this is a special one for ESP32, it won't work with Arduino
#include <BLEDevice.h>
#include <BLEServer.h>
#include <BLEUtils.h>

P3RGB64x32MatrixPanel matrix;

#define receiver 34
IRrecv irrecv(receiver);
decode_results results;

int var = 0;

bool deviceConnected = false;

void setup() 
{
  Serial.begin(115200);
  matrix.begin();

  irrecv.enableIRIn();
  matrix.println();

  delay(100);

  BLEDevice::init("ESP32");
  pServer = BLEDevice::createServer();
  //pServer->setCallbacks(new MyServerCallbacks());
  BLEService *pService = pServer->createService(SERVICE_UUID);
  pCharacteristic = pService->createCharacteristic(
                      CHARACTERISTIC_UUID,
                      BLECharacteristic::PROPERTY_READ   |
                      BLECharacteristic::PROPERTY_WRITE  
                    );
  pCharacteristic->setValue("");
  pService->start();
  BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();
  pAdvertising->addServiceUUID(SERVICE_UUID);
  pAdvertising->setScanResponse(false);
  pAdvertising->setMinPreferred(0x0);  // set value to 0x00 to not advertise this parameter
  BLEDevice::startAdvertising();
  Serial.println("Waiting a client connection to notify...");
}//setup

void loop() 
{
    if (irrecv.decode(&results)) 
    {
        translateIR(); 
        irrecv.resume(); 
    }//if

    if (deviceConnected) {
        var = 1;
    }
    delay(200);
}//loop

    switch(results.value)
    {      
        case 0xFF10EF:  
            Serial.println(" 4              ");
            matrix.fillScreen(matrix.color444(0,0,0));
            if(var==0) {
              matrix.setCursor(0,0);
              matrix.print("Disconnected");
            }
            if(var==1) {
              matrix.drawRect(15, 0, 47, 31, matrix.color444(15,15,15));
            }
        break;
