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

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Installing from PyPI

Warning: Linux support is very limited. See Adafruit Blinka _bleio <https://github.com/adafruit/Adafruit_Blinka_bleio>_ for details.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-ble/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-ble

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

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-ble

To install in a virtual environment in your current project:

.. code-block:: shell

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

Usage Example

.. code-block:: python

from adafruit_ble import BLERadio

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

print("scan done")
