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.

Install

pip install pybleno

Usage

from pybleno import *

bleno = Bleno()

See examples folder for code examples.

See the original nodejs Bleno documentation for usage.

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
