PROJECT: Open Source HomeBrew Repeater Proctol Client/Master.


PURPOSE: Thanks to the work of Jonathan Naylor, G4KLX; Hans Barthen, DL5DI; Torsten Shultze, DG1HT we have an open protocol for internetworking DMR repeaters. Unfortunately, there's no generic client and/or master stacks. This project is to build an open-source, python-based implementation. This is a non-commercial license. Atribution is required if you use it.

For those who will ask: This is a piece of software that implements an open-source, amateur radio networking protocol. It is not a network. It is not indended to be a network. It is not intended to replace or circumvent a network. People do those things, code doesn't.

This work represents the author's interpretation of the HomeBrew Repeater Protocol, based on the 2015-07-26 documents from DMRplus, "IPSC Protocol Specs for homebrew DMR repeater" as written by Jonathan Naylor, G4KLX; Hans Barthen, DL5DI; Torsten Shultze, DG1HT, also licenced under Creative Commons BY-NC-SA license.

WARRANTY None. The owners of this work make absolutely no warranty, express or implied. Use this software at your own risk.

This document assumes the reader is familiar with Linux/UNIX, the Python programming language and DMR.

Using docker version

To work with provided docker setup you will need:

  • A private repository with your configuration files (all .cfg files in repo will be copyed to the application root directory on start up)
  • A service user able to read your private repository (or be brave and publish your configuration, or be really brave and give your username and password to the docker)
  • A server with docker installed
  • Follow this simple steps:

Build your own image from source

docker build . -t millaguie/hblink:3.0.0

Or user a prebuilt one in docker hub: millaguie/hblink:3.0.0

Wake up your container

touch /var/log/hblink.log
chown 65000  /var/log/hblink.log
 run -v /var/log/hblink.log:/var/log/hblink.log -e GIT_USER=$USER -e GIT_PASSWORD=$PASSWORD -e GIT_REPO=$URL_TO_REPO_WITHOUT_HTTPS://  -p 54000:54000  millaguie/hblink:3.0.0
