    Set and get the time on various Bluetooth Low Energy clocks


This project offers a way to easily recognize Bluetooth Low Energy (BLE) clocks from
their advertisements and has a device-independent API to set and get the time on them.

Installation
============

You can install bluetooth-clocks as a package from PyPI with pip::

    pip install bluetooth-clocks

Usage of the command-line program
=================================

If you have installed the package with ``pip``, you can run the program as ``bluetooth-clocks``::

    $ bluetooth-clocks -h
    usage: bluetooth-clocks [-h] [--version] [-v] [-vv] {discover,get,set} ...

    Bluetooth Clocks

    options:
      -h, --help           show this help message and exit
      --version            show program's version number and exit
      -v, --verbose        set loglevel to INFO
      -vv, --very-verbose  set loglevel to DEBUG

    Subcommands:
      {discover,get,set}
        discover           discover supported Bluetooth clocks
        get                get the time from a Bluetooth clock
        set                set the time of a Bluetooth clock

Discovering Bluetooth clocks
----------------------------

You can discover supported Bluetooth clocks with ``bluetooth-clocks discover``::

    $ bluetooth-clocks discover
    Scanning for supported clocks...
    Found a ThermoPro TP358: address BC:C7:DA:6A:52:C6, name TP358 (52C6)
    Found a Xiaomi LYWSD02: address E7:2E:00:B1:38:96, name LYWSD02
    Found a ThermoPro TP393: address 10:76:36:14:2A:3D, name TP393 (2A3D)
    Found a Qingping BT Clock Lite: address 58:2D:34:54:2D:2C, name Qingping BT Clock Lite
    Found a Current Time Service: address EB:76:55:B9:56:18, name F15

These are the options that the ``discover`` subcommand recognizes::

    $ bluetooth-clocks discover -h
    usage: bluetooth-clocks discover [-h] [-s SCAN_DURATION]

    options:
      -h, --help            show this help message and exit
      -s SCAN_DURATION, --scan-duration SCAN_DURATION
                            scan duration (default: 5 seconds)

Setting the time
----------------

Set the time of a clock with a given Bluetooth address::

    $ bluetooth-clocks set -a E7:2E:00:B1:38:96
    Scanning for device E7:2E:00:B1:38:96...
    Writing time to device...
    Synchronized time

If you want to regularly synchronize the time on the device, you can run this command as a service, e.g. with a systemd service or in a cron job in Linux.

These are the options that the ``set`` subcommand recognizes::

    $ bluetooth-clocks set -h
    usage: bluetooth-clocks set [-h] -a ADDRESS [-s SCAN_DURATION] [-t TIME] [-p]

    options:
      -h, --help            show this help message and exit
      -a ADDRESS, --address ADDRESS
                            Bluetooth address (e.g. 12:34:56:78:9A:BC)
      -s SCAN_DURATION, --scan-duration SCAN_DURATION
                            scan duration (default: 5 seconds)
      -t TIME, --time TIME  the time to set, in ISO 8601 format (e.g. 2023-01-10T16:20,
                            default: current time)
      -p, --am-pm           use AM/PM format (default: 24-hour format)

Getting the time
----------------

Get the time from a clock with a given Bluetooth address::

    $ bluetooth-clocks get -a E7:2E:00:B1:38:96
    Scanning for device E7:2E:00:B1:38:96...
    Reading time from device...
    2023-01-14T17:54:17

These are the options that the ``get`` subcommand recognizes::

    $ bluetooth-clocks get -h
    usage: bluetooth-clocks get [-h] -a ADDRESS [-s SCAN_DURATION]

    options:
      -h, --help            show this help message and exit
      -a ADDRESS, --address ADDRESS
                            Bluetooth address (e.g. 12:34:56:78:9A:BC)
      -s SCAN_DURATION, --scan-duration SCAN_DURATION
                            scan duration (default: 5 seconds)

Usage of the library
====================

The functionality of the command-line program can also be used in your own Python programs by using this project as a library.

See the `module reference <https://bluetooth-clocks.readthedocs.io/en/latest/api/modules.html>`_ for complete API documentation.
