[Question] How to use Bluedroid instead of NimBLE in Arduino IDE (v3.3.0)? #11821
Description
Related area
BT
Hardware specification
ESP32-S3
Problem
After updating to Arduino-ESP32 v3.3.0, the default BLE stack is NimBLE.
My code uses Bluedroid-specific APIs (e.g. startExtScan), so it no longer compiles.
In v3.2.1 this worked fine.
Question
In Arduino IDE, is there a way to switch the BLE host stack from NimBLE back to Bluedroid?
For example, using build_opt.h, platform.txt, or some other configuration?
What I tried
- Added -DCONFIG_BT_BLUEDROID_ENABLED=1 -DCONFIG_BT_NIMBLE_ENABLED=0 in build_opt.h → did not work.
- Edited platform.txt extra_flags → still NimBLE is forced.
- I know PlatformIO or ESP-IDF as component can solve this, but I want to stay with Arduino IDE if possible.
Environment
- Arduino IDE 2.x
- Arduino-ESP32 v3.3.0
- Board: ESP32-S3
- OS: Windows
