v4.9.0

Features

Gateway Mesh

This is a new feature that makes it possible to extend network coverage by deploying ‘Relay Gateways’ that operate without internet access. While the Gatway Mesh only requires changes to the LoRa Gateways, this implements an overview of detected Relay Gateways and their last heartbeat. Please see ChirpStack Gateway Mesh for for information. Support for this feature will be implemented in the next ChirpStack Gateway OS version.

The ChirpStack Gateway Mesh looks great.
I will try it in ChirpStack GatewayOS.

Hope this feature will be available in many commercial gateways too.

Thanks a lot for the effort.

Btw, could the gateway hop in the middle receive uplinks and downlinks from devices in its range?

Thanks a lot.

Yes, A Relay Gateway within the mesh is able to relay data from / to an other Relay Gateway and from LoRaWAN end-devices. I’m currently working on updating all the GW OS packages and doing some last testing. I expect there will be a GW OS release next week.

Ok, thanks a lot.
Will love the feature.

I am very interested in replacing the default tile server with our own existing tile server for mapped helium and private gateways.

As we use a docker instance what is the expected way to utilise this? is there a config in the chirpstack.toml i can set our tile server address with?

7

There is, I noticed that I didn’t update the ChirpStack config example, the example now contains the new config options.

ok thanks i put the new config into the toml. I have commented it out to get it to run atm just the attribution at the bottom.

do gateways need to added on to into the external tile server? It it just loading blank, or maybe related to the attribution problem?

parse error for the attribution.

super excited if we can get this to work!

I think I need to fix that, it is an escaping issue in the template, see:

Make sure that the " are escaped within the map_attribution="...."

Hi @brocaar
Since LoRaWAN signal is quite far, is there any “testing mode” to test and see how the Gateway mesh works in a shorter range (says in 100m).

For simulated test, we may set gateway A to receive signal from gateway B only…
And only gateway C has internet access.

Thanks a lot.

There is the feature for to ignore direct uplinks. Probably not exactly what you need to test multiple hops in low area but helpful for a single hop.

So great.
Let me try.
Thanks a lot.

Is there a way to set the admin and tenant admin role for the OIDC user?

14

Yes, you can use the registration callback URL to modify the user, setup a tenant etc…

15

Thanks for the reply @brocaar.
So just for my understanding:

Chirspstack doesn’t support automatic role mapping from OIDC claims, but a custom endpoint needs to be used that will interact with the ChirpStack API to create/update users?
