bluepy3 1.10.2

Python module for interfacing with BLE devices through Bluez

This is a Python3 library to allow communication with Bluetooth Low Energy devices on Linux.

###### Note: If you are reading this on [PyPi](https://pypi.org/project/bluepy3/) then note that the formatting below looks terrible. Visit the project’s homepage to read the correctly formatted [README.md](https://github.com/Mausy5043/bluepy3#readme) file.

## Requirements

Please be aware that this is not a beginners tool. Some experience with Linux CLI, Python3 and BT/BLE is expected.

The package has been extensively tested on a Raspberry Pi 3 Model B+ (aarch64) with Debian GNU Linux 11 kernel 6.* and Python 3.9.*. It requires Python v3.7 or higher to be installed.

The code needs an executable bluepy3-helper which is compiled from C source automatically if you use the recommended pip installation method (see below). Otherwise, you can rebuild it using the Makefile in the bluepy3 directory.

The bluepy3 package comes installed with lists of compatible UUIDs in uuids.json. If, for whatever reason, you want to rebuild those lists, then the Python3 modules bs4, requests and lxml need to be installed. `(python3) python3 -m pip install bs4 lxml requests ` Then find where the bluepy3 package is installed and rebuild uuids.json thus: `(bash) cd some_path_name/site-packages/bluepy3/ make uuids.json `

## Installation

To install the current released version, on most Debian-based systems: `(bash) sudo apt-get install libglib2.0-dev libbluetooth-dev python3 -m pip install --upgrade bluepy3 ` Then test the installation using: `(bash) sudo setcap cap_net_raw,cap_net_admin+ep $(find . -name bluepy3-helper) blescan -n sudo hcitool lescan ` This should list all (compatible) Bluetooth devices in range.

It may be considered to have command-line tools from BlueZ available for debugging. There are instructions for building BlueZ on the Raspberry Pi at http://www.elinux.org/RPi_Bluetooth_LE.

## Troubleshooting

Make sure the user is part of the bluetooth group. Use hciconfig to confirm that the device actually exists. This should output something like: ` hci0: Type: Primary Bus: UART BD Address: B8:27:EB:90:4F:F5 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX bytes:15332515 acl:452626 sco:0 events:333729 errors:0 TX bytes:7376962 acl:438075 sco:0 commands:72113 errors:0 ` Use hciconfig [hci0] up to activate the BT device if the above returns an error.

Although Python v3.7 will still work, official support for v3.7 is dropped as of JUN2023 since that is EOL. It is advised to upgrade your Python installation to v3.9 or above.
