AREDN code repositories on GitHub

The AREDN source code repositories are now accessible on GitHub at https://GitHub.com/aredn/aredn_ar71xx .   GitHub is one of the largest open source hosting services with over 40 million users.   Anyone with basic knowledge of Linux and git can now compile AREDN images and contribute changes.   If you have a background in application or firmware development, the hurdle to get started and contribute to the ham community is now much lower.

GitHub also includes an issue tracking feature to capture feature requests, bug reports, and other issues.  This immediately replaces our former defect tracking tool (Bloodhound).
 

​AREDN GitHub Activity

The GitHub setup is intended to jump AREDN forward to stay current, and benefiting from, the 1000+ developers of Linux and OpenWrt releasing a steady stream of advancements and fixes.    AREDN is now based on this stream.  By staying current, our community is able to focus on those features unique to the ham community.

The OpenWrt group produces a major release each year followed by 3 or 4 point releases in successive months.   The latest release candidate was published in June 2018 with a final release targeted in July.

​AREDN Donates Mesh Networking Equipment to ARRL

 

High-Speed Multimedia Mesh (HSMM) technology has evolved rapidly in recent years due to the development efforts of the Amateur Radio Emergency Data Network (AREDN) open source project. This has changed the complexion of mesh implementations from an experimental, hobby-oriented, novelty into a viable alternative network suitable for supporting high-speed emergency communications and Internet connectivity when “all else fails.”

The AREDN project team recently donated the following equipment to the ARRL Laboratory:

  • Two Ubiquiti Nanostation M3’s for 3.4 GHz
  • Two Ubiquiti Nanostation Loco M5’s for 5.8 GHz
  • One PowerBeam PBE-M5-300-ISO for 5.8 GHz
  • One AirRouter HP (combination 2.4 GHz and Ethernet switch)

The AREDN (pronounced “r-den”) project is working with ARRL, the national association for Amateur Radio to inform the amateur radio community about this high-speed, low-cost networking technology. To further our shared goal of supporting emergency responders, AREDN has donated a substantial kit of mesh networking equipment to the ARRL for their familiarization and deployment. Both groups plan to work together to provide written guidance on the best practices for using this networking capability to provide such services as voice-over-IP telephony (VoIP), streaming video, email, and much more.

California Hams Provide Fire Videos


Local amateur radio operators are responding to the recent and ongoing fires in California in many ways. Several of these hams have built a high-speed multimedia AREDN mesh network which was used to deliver live streaming video of the fires in progress.

In Ventura County, Orv Breach W6BI, Paul Straus WD6EBY and Ben Kuo AI6YR installed high-definition cameras in their portion of the growing Southern California AREDN network. They were able to figure out how to send to live video stream across the mesh network to then Internet and finally to YouTube for public access.

Ben AI6YR reports that their mesh network stayed operational even when the Spectrum cable, Internet access and phone system went down across the region. People were able to use the mesh network to keep updated on emergency information.

Ham Radio 2.0 Interviews AREDN Developers

Jason KC5HWB continues to produce a great series of ham radio videos on YouTube. In Episode 159, Jason interviews Joe AE6XE and Darryl K5DLQ from the AREDN development team. They describe the many improvements in the latest AREDN release version 3.18.9.0 and talk about the development process. They discuss the expanded list of supported devices which now includes the newer Ubiquiti AIrMax models and several units from Mikrotik.Joe and Darryl tell the viewers about our plans to provide a Raspberry Pi firmware installer which is being developed by K6RUN. 

Subscribe to Jason's YouTube channel and visit his website HamRadio2.0 Live from the Hamshack.


Installation Instructions for Mikrotik Devices


Download the Mikrotik .bin and the .elf file from downloads.arednmesh.org location:

  •  elf  :  this is the image to boot the mikrotik device with.  It only uses RAM on the device (which is lost with a power cycle and still boots with Mikrotik OS)
  • .bin :  once the device is booted with the .elf image and running,  copy this up to /tmp and type a command that will update the flash with AREDN, so it then boots AREDN on a power cycle.
 
The procedure is very different and it is the opposite of a Ubiquiti installation.  Opposite in that with Ubiquiti, the device is a tftp server and the tftp client is run on the laptop to send up the image.  With Mikrotik, the device is a tftp client and the laptop has to be configured to run a tftp server (also dhcp and bootp server)  on a linux or windows machine.    This is all done by a program called dnsmasq (it has all 3 servers).  
 

Linux procedure:

 
  1. Create a directory on your laptop /tftp ...
