This module provides higher-level BLE (Bluetooth Low Energy) functionality, building on the native _bleio module.


This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

Warning: Linux support is very limited. See Adafruit Blinka _bleio for details.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-ble

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-ble

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ble

Usage Example

from adafruit_ble import BLERadio

radio = BLERadio()
found = set()
for entry in radio.start_scan(timeout=60, minimum_rssi=-80):
    addr = entry.address
    if addr not in found:

print("scan done")
