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 requires Python 3 v3.7 or higher to be installed. It has been extensively tested on a
Raspberry Pi 3 Model B+ (aarch64) with Debian GNU Linux 11 kernel 6.1.19-v8+.
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.
