BLE Client exemple works on Arduino IDE but dont works on PlatformIO

[gsc126]

Im a student trying to read the temperature on a generic BLE Beacon using a ESP32-WROOM-32U. When i use the BLE client example on the Arduino IDE Version 1.8.19, ESP32 - Version 2.0.4 using the native lib “ESP32 BLE Arduino” it works well, read the temp, all ok.

But when i upload the exactly same code using VsCode 1.69.1 and the same lib “ESP32 BLE Arduino” Version 2.0.0, compile and upload, but when it run, i get this error:

Forming a connection to d4:b4:96:29:d5:b0
- Created client
- Connected to server

Rebooting...

I understand that in someway my code is making a stackoverflow, i already tried to modify the partition scheme using this https://geekelectronick.com/esp32-customizing-partition-in-platformio/ and reducing the massive use of serial.print but dont work.

I tried some of the tips here nkolban/esp32-snippets#874 but dont work too.

When i change the line on the platformio.ini to platform = [email protected] then compile, upload, the code works with no problem.

The configuration on platformio.ini:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
Below the code im using:
