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 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

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 https://github.com/nkolban/esp32-snippets/issues/874 but dont work too.
The configuration on platformio.ini:

The configuration on platformio.ini:
platform = espressif32
Then instead of writing this, write
platform = [email protected] and reupload.
Otherwise with the more recent versions you get a 2.x core. (Releases · platformio/platform-espressif32 · GitHub)
