Bluetooth connection between two ESP32 Worms

I made a screen, with a text widget, it works in arduino id.
If I paste the BluetoothSerial library, I get the following error message:

…\ld.exe: region `dram0_0_seg’ overflowed by 1240 bytes
collect2.exe: error: ld returned 1 exit status

(If I don’t create this project with Studio using lvgl, then BluetoothSerial works.)


  • SquareLine Studio version:1.3.4
  • Operating system:Windows10 / Arduino IDE 1.8.19
  • Target hardware:ESP32-2432S028R 2.8" TFT

It seems as if the code have exceeded available RAM. Maybe setting LV_MEM_CUSTOM to 1 or LV_MEM_SIZE to a bigger value in lv_conf.h will give you more available memory…
