A C++ Arduino library wrapping the Apache NimBLE Bluetooth Low Energy stack for Espressif ESP32 and Nordic nRF51/nRF52 microcontrollers. It offers a lighter, faster alternative to the bluedroid-based ESP32 BLE library while keeping a similar API.

Use cases

• build a BLE peripheral server on ESP32 with Arduino
• scan for BLE beacons with an nRF52 board
• create a BLE client that connects to heart rate sensors
• reduce memory usage of ESP32 BLE applications
• implement BLE Eddystone beacons in Arduino sketches
• use a fully open-source BLE stack on Nordic chips without softdevice

When to choose

• you need BLE on ESP32 or nRF5x within Arduino or PlatformIO
• the default bluedroid ESP32 BLE library is too resource-heavy or slow
• you want an actively maintained, open-source BLE stack with full debugging on Nordic devices

When to avoid

• you are building with ESP-IDF directly (use esp-nimble-cpp instead)
• you need BLE on non-supported microcontrollers
• you rely on the exact bluedroid API without any code migration
