Hytera Homebrew Bridge

21.12.2020: We've entered alpha testing phase, see instructions below, on how to install and test

This software will interconnect your Hytera repeater (tested RD625 and RD985) with MMDVM server (HBlink, DMRGateway, ...)

It does not require running under root/admin user, if you bind to ports over 1024

Simple install:

# You need to have Python3 installed, at least version 3.7
$ python3 -m pip install pip wheel setuptools --upgrade
$ python3 -m pip install hytera-homebrew-bridge --upgrade
# download config file
$ curl "https://raw.githubusercontent.com/OK-DMR/Hytera_Homebrew_Bridge/master/settings.ini.minimal.default" -o settings.ini
# Now edit settings.ini
# Hytera: You must provide at least IPSC IP + ports (P2P, DMR and RDAC)
# MMDVM: You must provide at least local_ip, master_ip, port and password
# See "settings.ini.minimal.default" for required params / minimal configuration
$ hytera-homebrew-bridge.py settings.ini

Install on Windows

To get software running on Windows, you need to install appropriate Python 3.7+ package (depending on your Windows version), and you need to install dependencies (MSVC++ 14) required to build bitarray dependency

• Microsoft Visual C++ Build Tools v14.0
  • Use visualcppbuildtools_full.exe and install with default configuration

Then you should be able to use Simple install

# From standard Windows Command Line (cmd.exe)
$ python -m pip install pip wheel setuptools --upgrade
$ python -m pip install hytera-homebrew-bridge --upgrade
# Download settings from the project, settings.ini.minimal.default or settings.ini.default and modify it
$ hytera-homebrew-bridge.py <path to settings.ini> <optinally path to logging.ini>

Developer install:

Run the software without installing to Python packages, so you can edit code and run the edits

# Optionally uninstall the version installed in system
# python3
$ git clone https://github.com/OK-DMR/Hytera_Homebrew_Bridge.git
$ cd Hytera_Homebrew_Bridge
# You can use either settings.ini.default (all configuration params) or settings.ini.minimal.default (only required params)
$ cp settings.ini.default settings.ini
$ apt-get install libsnmp-dev snmp-mibs-downloader gcc python-dev
$ python3 -m pip install -r requirements.txt --user --upgrade
# Dependencies to run tests (pytest, pcapng parsing, ...)
$ python3 -m pip install -r requirements.development.txt --user --upgrade
$ python3 bin/hytera-homebrew-bridge.py settings.ini

FAQ

• Q: Difference between SNMP family/community 'public' and 'hytera'?
  • A: Some repeaters have non-changeable SNMP setting, and it appears it is usually either 'public' or 'hytera', if SNMP does not work for you, try changing the value to the other one
• Q: RDAC identification restarts unexpectedly or does not work at all, what can I try to fix it?
  • A: Check the programming in CPS, there might be multiple incorrect settings
    1. Open Conventional > Channel > Digital Channel (or analog) > Digital IP Multi-Site Connect (4th from top in channel detail) must be set to "Slot 1 & Slot 2"
    2. Open Conventional > General Settings > Access Manager and in the section "Multisite Access Management" either disable the management or set correct list
• Q: SNMP does not work correctly, what can I try to fix it?
  • A: Check if SNMP port is set to 161 in Conventional > General Settings > Network section SNMP at the bottom
• Q: I'm not getting the upstream connection and/or I'm seeing a lot of logs similar to "MMDVMProtocol - Sending Login Request"
  • A: This is usually misconfiguration of Hytera repeater, if you do not see any logs with 'RDAC' or the long packet with 'REPEATER SNMP CONFIGURATION' info. In such cases you should check if the Hytera repeater is programmed correctly as slave and the IP/ports do match the HHB startup log saying 'Hytera Repeater is expected to connect at xxx.xxx.xxx.xxx'
