Introducing an AREDN Chat client

Meshchat has been the go-to chat client for most users of AREDN networks. But because AREDN is a communications network software, and the core team has been reluctant to move into apps, support of Meshchat has been hit-and miss.

So the AREDN team has decided to step up to the plate with an AREDN-supported chat client, called Raven. It has a nice set of features:

  • Realtime text messaging.

  • Runs on any AREDN-supported hardware that's running current AREDN software (but see recommendations in the wiki).

  • Can communicate with other Raven clients via AREDN.

  • Can communicate between AREDN meshes via Supernodes

  • Supports talking on a Meshtastic network (requires additional hardware)

  • Supports talking on a Meshcore network (required additional hardware, and integration is very involved. Documentation will eventually be provided).

  • Supports multiple channels per node.

  • Supports sharing images.

  • Supports sharing Winlink forms.

Not compatible with MeshChat (it...

AREDN production release 4.26.1.0 is now available


This release is the first AREDN production release that omits the legacy OLSR protocol, and consequently the first release with the major number 4. That may sound scary, but if all your local nodes are on 3.25.5.0 or greater, they already speak Babel. That means a migration to this production release should pretty much be a non-event for your network.
If you are upgrading to 4.26.1.0 from a babel nightly build, you may see the following message:

BEWARE: Downgrading firmware WILL result in a broken or incomplete node configuration.
This can be safely ignored during this upgrade.

AREDN Release 3.25.10.0 with 802.11ah Support


The AREDN Dev team has released version 3.25.10.0 of the AREDN software,

AREDN Development Plans

 

A heads up on AREDN software development plans


AREDN®, as we’ve come to know it, is 11 years old. In that time it has come a long way, supporting a wide variety of devices, a host of radio bands, and has been deployed across the world. The UI has evolved, tunnels have been added, bandwidth and throughput have increased, and more features and services can be supported. The one constant in all this has been how AREDN® manages the network, using a protocol called Optimized Link State Routing - OLSR. Unfortunately as networks have grown, this protocol has buckled, and sometimes broken, under the strain, as OLSR was never designed for the size or variety of the networks we have. This year we added a new modern network protocol - Babel (see the How-To in the online documentation for more information). The goal has been to replace OLSR after a period of testing and migration, and we imagined it might take years to successfully transition from one protocol to the other. Instead, we have been blown away by how our community has embraced and requested this change. As of this writing, almost 80% of nodes worldwide are running firmware which uses the Babel protocol.
 With this in mind, we have decided to move more quickly...
