## PROJECT: Open Source HomeBrew Repeater Proctol Client/Master. ##

**UPDATES:**

**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. You are free to use this software however you want, however we ask that you provide attribution in some public venue (such as project, club, organization web site). This helps us see where the software is in use and track how it is used.

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 intended to be a network. It is not intended to replace or circumvent a network. People do those things, code doesn't.
  
**PROPERTY:**  
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.

**PRE-REQUISITE KNOWLEDGE:**  
This document assumes the reader is familiar with Linux/UNIX, the Python programming language and DMR.  


**Using the docker version**

Build the docker image.

```bash
docker build --tag freedmr .
```

Start your container, passing your configuration file.

```bash
cfg_file="/absolute/path/to/cfg/file"
docker run -v $cfg_file:/opt/freedmr/hblink.cfg -p 54000:54000 freedmr
```

Note that `$cfg_file` is used by the container's 'radio' user internally, so you may need to modify file permissions.

```bash
chmod 666 $cfg_file
```

**MORE DOCUMENTATION TO COME**
