RAK2245 RasPi3 Hat TTN Not Connected

It was pretty hot here on Saturday. I would call it a scorcher in my book.

This is bizarre. These are my coordinates, but not my EUI. Not sure how that happened.

{“eui-b827ebfffee6cbe6”:{“id”:“eui-b827ebfffee6cbe6”,“location”:{“latitude”:41.56465148925781,“longitude”:-90.51200103759766,“altitude”:206},“country_code”:“us”,“attributes”:{“brand”:“Raspberry Pi based”,“frequency_plan”:“US_902_928”},“last_seen”:“2020-07-20T14:52:32Z”}}

For here in the UK, that’s furnace level - I’d have spent the day in the bath.

If you try and create a new gateway using the EUI in your conf file, does the console complain about a duplicate?

Yes it does.

Hmmm, the one in your conf file returns no info on the gateway-data url but there is that other one in the database for your location. Clearly the server has had a ‘moment’.

I think we need to get @arjanvanb to page the back room wizards to de-borf the entries so you can try again with a clean slate.

I’ve no more power than you mortals. :wink: Anyone can try to summon, e.g., @KrishnaIyerEaswaran2 or @htdvisser:ghost:

Beware: we cannot be sure that eui-b827ebfffee6cbe6 is not someone else’s, especially as it’s clearly connected. But eui-b827ebfffeb39eb3 surely seems to be in some troubled state within TTN.

Did you restart the gateway recently? Does the 6cbe6 one go offline when you switch off yours? (Aside: its coordinates and altitude seem to be changing a bit over time, suggesting a GPS.)

Those GPS coordinates point to my house. That is one heck of a coincidence. I think I would know if someone was breaking into my house and setting up a TTN gateway. I will power mine down to see if that change is reflected in the console. Thank you!

Now I have the power - if you’ve got a cheat sheet on the URLs you use for diagnosis, it would save me trawling through previous posts to make sure I’ve got them all!

Kids? Significant other? Grandma? Maybe they are all next door laughing their a55 off?

Not really, except for Determine which gateway is used by a given node - #12 by arjanvanb. And the forum’s bookmarking functionality helps, but I’ve started using that too late. So it’s mainly search for keywords I remember…

@arjanvanb @descartes This device seems to have fallen over since I powered down my device. I would say the evidence is starting to mount. My gateway is going by an alias. Its some sort of undercover rogue agent.

Whilst it fills me with a random range of uncomfortableness but given that the EUI is generated from the Pi’s MAC address so isn’t a “real” one and if you change Pi, it won’t change in the config, let’s try changing your EUI on the device to the one that TTN thinks you have.

Or, if you have the patience, re-install the whole gateway just in case you have multiple Pi’s and we have some re-generation of the EUI issue going on.


…which it probably has multiple? Like WiFi and ethernet?

Can you actually still register the 6cbe6 one? Probably not, given it has a description from somewhere.)

@descartes @arjanvanb I powered the device back on. Then I updated the global configuration and restarted the packet forwarder. I noticed the device started updating again. I then went to register a gateway with b827ebfffee6cbe6 as the EUI and this time it accepted it without issue. The gateway is now showing up in the console with EUI of b827ebfffee6cbe6 and it shows as connected. I also still have the old not connected gateway too. I figure I will just leave that one in case it somehow one day magically reverts to that value. I believe I do have both Ethernet and WiFi configured on that pi. I didn’t realize the EUI was based on the interface’s MAC address. I am betting that is how I got one EUI registered and another one that was actually working based on how traffic was routed. Thank you both for all of your help! I guess I am going to move on to configuring my node and learning how to use the MQTT API. Thank you again, it is much appreciated!

You’re welcome!

Aside, right now, status still fails for both gateways, but info works, for both, as in:

  • ttnctl gateways info eui-b827ebfffee6cbe6 (with owner details)
  • ttnctl gateways info eui-b827ebfffeb39eb3 (no owner)

(I assume that my EU868 settings for ttnctl should also work for ttnctl gateways status eui-b827ebfffee6cbe. Oh well. Maybe it will take some time.)

@arjanvanb Seems to be working over here. Perhaps there is some sort of replication that occurs cross region? Thank you.

Yes, you’re showing info. But the following, using the undocumented status (which can often be used when TTN Console shows gateways as being disconnected), still fail for me:

  • ttnctl gateways status eui-b827ebfffee6cbe6
  • ttnctl gateways status eui-b827ebfffeb39eb3

Ah, I see. I misread your command the first time. I am also getting failed when I run the status command. Does the status command require that ports are forwarded or anything like that for the gateway to respond? I don’t have any of that setup at this time. Thank you.

As far as I know, ttnctl does not cmmunicate with the gateways directly. Surely the EU868 gateways that I manage do not have any incoming ports open from the internet, but surely status works just fine. Like:

  • The Things Gateway, using MQTT: ttnctl gateways status arjanvanb-gw-1
  • Kerlink IoT Station, using Semtech UDP forwarder: ttnctl gateways status eui-0000024b080606d8

It often is, because that’s unique, but it doesn’t have to be

Probably. Seems like a case of scripts running amok and doing the generation step at multiple times, then changing the configuration files without making it clear they’ve done so.

These days I simply install the two repositories needed - the packet forwarder and the lora hal on which it depends, set the config file, and add an OS-appropriate way of running it as a daemon (systemd, init.d, procd, whatever)
