akvadrako/pybleno repository overview

Fork notes (akvadrako/pybleno)

⁠pybleno

A direct port of the Bleno bluetooth LE peripheral role library to Python2/3

The logic of this library was originally written by Sandeep Mistry (https://github.com/sandeepmistry/bleno⁠), and this repository is a direct port of that code-base. A huge thanks to Sandeep for his solid library.

Effort has been made to maintain the same code structure to aid in parallel maintenance with Bleno.

Note: Currently only tested on Linux Raspbian

⁠Prerequisites

Please read the original nodejs Bleno prerequisites⁠, failure to meet these may result in 'Operation not permitted' errors at runtime.

Python must be compiled with support for Bluetooth or you will get errors like:

AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH'

⁠Install

pip install pybleno

⁠Usage

from pybleno import *

bleno = Bleno()

See examples folder⁠ for code examples.

See the original nodejs Bleno documentation for usage.

⁠On Linux

pybleno requires access to raw network sockets. That means you need to run your programs as root or do this first:

sudo setcap cap_net_raw+eip $(eval readlink -f `which python`)

⁠Docker

docker build -t pybleno .
docker run --name pybleno --rm --privileged --net=host pybleno

⁠Troubleshooting

• Symptoms: Peripheral stops responding, notifications not going through - pi must be rebooted. Kernel log contains hci0: Frame reassembly failed
  • Cause: Bugs in bluetooth kernel module - manifests whe running Raspbian <= 2018-11-13.
  • Fix: apt-get upgrade
