- NimBLE-based host APIs
ESP-IDF currently supports two host stacks. The Bluedroid based stack (default) supports classic Bluetooth as well as BLE. On the other hand, Apache NimBLE based stack is BLE only. For users to make a choice:

Code examples for this API section are provided in the bluetooth/bluedroid directory of ESP-IDF examples.
The following examples contain detailed walkthroughs:
