BLE client disconnect causes reboot

[PeterAndersson]

Hi i have the following code

Code: Select all

#include <BLEDevice.h>
#include <BLEAddress.h>

void setup() {
  Serial.begin(115200);
  // put your setup code here, to run once:
  BLEDevice::init("");
}

static BLEUUID           serviceUUID("00001204-0000-1000-8000-00805F9B34FB");
static BLEUUID        modeChangeUUID("00001a00-0000-1000-8000-00805f9b34fb");

void loop() {
  for(int i = 0; i < 5; i++) {
    delay(1000);
    Serial.print('.');
  }
  
  writeToDevice();
  Serial.print("Sleeping");
  for(int i = 0; i < 5; i++) {
    delay(1000);
    Serial.print('.');
  }
  Serial.println("");
}

void writeToDevice()
{
  Serial.println("");
  Serial.println("Connecting");
  // put your main code here, to run repeatedly:

  BLEClient* client = BLEDevice::createClient();
  BLEAddress bleAddress = BLEAddress("C4:7C:8D:63:7C:15");
  bool connected = client->connect(bleAddress);
  if (connected)
  {
    
    Serial.println("Connected");
    Serial.println("Getting service");
    auto service = client->getService(serviceUUID);
    Serial.println("Writing change mode bits");
    service->setValue(modeChangeUUID, "\xA0\x1F");
    
    Serial.println("Disconnecting");
    client->disconnect();
  }
  else
  {
    Serial.println("Failed to connect");
  }
}

But when i call client->disconnect(); i get the following error:

22:59:36.292 -> SleepingCORRUPT HEAP: Bad head at 0x3ffe17b4. Expected 0xabba1234 got 0x3ffe1800

I'm using a Adafruit ESP32 Feather.

What am i doing wrong?

Use this tool:

Also you probably have issue with memory leak in your code.
