If you are already on 220.127.116.11b01, then you can easily use the OTA (Over the Air) "keep settings" upgrade! Joe (AE6XE) did his first 5+mile remote-over-RF upgrade and saved an afternoon and a long uphill hike (This was on a Ubiquiti 3Ghz node). We've had some great feedback on the "part 97 only" channels where they have significantly improved link quality results
In addition, these are 'clean' image upgrades that minimize memory usage. Whenever 'patch' files are used on nodes, this is a memory additive process. In other words, a replaced file still has old file on the node in addition to the new the file. These BOTH consume precious system memory. The OTA upgrade, on the other hand, behaves as if you did a TFTP "clean" image load, but also pulls the config file settings across the upgrade! It's a VERY COOL timesaver.
For those of you with tunnels, you will need to go into the Admin interface...
On May 28th, the AREDN Project released to its team of volunteer testers, a new beta-version of its upcoming release, v18.104.22.168. This is the most significant and important release since this development team introduced support for the Ubiquiti AirMax line of hardware back in 2013.
Here is a list of some of the new features:
The AREDN team will be attending the 35th Annual ARRL and TAPR Digital Communications Conference on September 16-18, 2016, St Petersburg, FL.
Our very own, Andre, K6AH, will be presenting an update on the AREDN project at 1:00 pm on Friday September 16. His paper builds on an AREDN paper published in the proceedings of the ARRL and TAPR 34th Digital Communications Conference 2015. Where that paper introduced the technology and the work of the AREDN Project software development team, this paper picks up where that leaves off and describes techniques for deploying AREDN in support of AUXCOM.
We plan to be in the demo room to show some AREDN applications. We would love to see you there.
A map of the currently known AREDN nodes is available under the Map menu item on the main menu bar. You can also download KML files of the node location to use with Google Earth.
The collection of How-To articles is now found as a sub-menu under the Docs menu item on the main menu bar.
Please consider uploading the coordinates of your AREDN nodes per the instructions below.
If you choose, you can specify your latitude, longitude, and gridsquare for location purposes. The lat/lon values should be in decimal format (ex. 30.444522 and -95.111234).
The Find Me! button to use your location aware browser to populate the values. This works very well if you are viewing this page from a mobile device with a built-in GPS.
Use the Apply Location Settings button to persist the lat/lon and gridsquare values. A "Save Changes" button click is not required for these settings.
If you have an active internet connection available, the...
Use an Ubiquiti ToughSwitch to Remotely Control Power to a Raspberry Pi
I include a Raspberry Pi “utility” computer at each mountain-top site. The challenge is… what happens if it locks up. Traveling there to power-reset it can be really inconvenient. So I got to wondering what it would take to use the existing ToughSwitch to power-control the Pi. Here’s how I decided to approach it.
Sourcing the Pi power this way allows you to perform power control through the ToughSwitch management interface. Using parts sourced from eBay, this comes in...Read More
Device-to-Device Linking (DtDLink)
The following figures show various ways to connect multiple nodes together at a single site.
The 802.1q switch and the AREDN nodes implement VLANs as follows:
