Bluetool

A simple Python API for Bluetooth D-Bus calls. Allows easy pairing, connecting and scanning. Also provides a TCP-to-RFCOMM socket bridge for data transfer.

Dependencies

  • python-dbus
  • tcpbridge

The package was tested with Python 2.7

Installation

pip install bluetool

or clone and run make install

Usage

  • Bluetooth:

    list: [{"name": Name, "mac_address": MAC-address}, ... ]

    Methods of class Bluetooth:

    • start_scanning(timeout): scan in background
    • scan(timeout)
    • get_devices_to_pair(), returns list
    • get_available_devices(), returns list
    • get_paired_devices(), returns list
    • get_connected_devices(), returns list
    • make_discoverable(), returns bool
    • start_pairing(address): pair in background
    • pair(address), returns bool
    • connect(address), returns bool
    • disconnect(address), returns bool
    • trust(address), returns bool
    • remove(address), returns bool
    • set_adapter_property(prop, value), returns bool
    • get_adapter_property(prop)
    • set_device_property(address, prop, value), returns bool
    • get_device_property(address, prop)

  • BluetoothServer:

    • Step1: Use run() to create SPP
    • Step2: Connect the bluetooth device
    • Step3: TCPServer is available for connection

    Use shutdown() to shutdown server.

Examples
  • Scanning
from bluetool import Bluetooth


bluetooth = Bluetooth()
bluetooth.scan()
devices = bluetooth.get_available_devices()
print(devices)
  • Using the RFCOMM-TCP Bridge
import signal
from bluetool import BluetoothServer


def handler(signum, frame):
    server.shutdown()


tcp_port = 8100
server = BluetoothServer(tcp_port)

signal.signal(signal.SIGINT, handler)
signal.signal(signal.SIGTERM, handler)

server.run()
  • Using the Bluetooth Agent
import signal
from bluetool.agent import Client, AgentSvr


class MyClient(Client):

    def request_pin_code(self, dev_info):
        print(dev_info)
        return raw_input("Input pin code:")

    def request_passkey(self, dev_info):
        print(dev_info)
        return raw_input("Input passkey:")

    def request_confirmation(self, dev_info, *args):
        print(dev_info, args)
        return raw_input("Input 'yes' to accept request:") == "yes"

    def request_authorization(self, dev_info):
        print(dev_info)
        return raw_input("Input 'yes' to accept request:") == "yes"


def handler(signum, frame):
    svr.shutdown()


svr = AgentSvr(client_class=MyClient)

signal.signal(signal.SIGINT, handler)
signal.signal(signal.SIGTERM, handler)

svr.run()

About the project

This package was written by Aleksandr Aleksandrov working at Emlid.

The bluetool was originally written for the Emlid Reach RTK receiver, but we decided to open source it, as there is no easy Python API for BT pairing/connecting. Feel free to add issues and submit pull requests.
