Can't get the Mikrotik LR8 connect to TTN

[rainerfritz (Rainer)]

Hi !

Sorry to ask for help or double post, but my knowledge on router configuration is not that good and I have still not managed to get it connected to TTN EU network. Similar posts did not point me in the correct direction.
Here is my configuration:

I added port forwarding for port 1700 udp and tcp on my ISP router in client mode.
I also added in the firewall of the mikrotik that udp and tcp is allowed on eth1.
But still no luck to get it connected to TTN.
Any help would be much appreciated.
Thx

One of our community members reported the same issue yesterday. They have multiple Mikrotik gateways installed, and a similar configuration as yours always worked. But a gateway installed yesterday did not want to come online on TTN V2.

[rainerfritz (Rainer)]

After resetting the mikrotik lr8 configuration with option to not generate the default config we managed to get it first connected to V3. No chance to connect it to v2. Now after two days in V3 it is also active in V2 without any interaction or changes.
So it is running now…

@rainerfritz

Now after two days in V3 it is also active in V2 without any interaction or changes.

What do you mean, that have one single gateway connected to V2 and V3?

[rainerfritz (Rainer)]

Yes with the Mikrotik Lora8 Kit and when you configure it with the winbox you can define two or more servers in parallel to forward the packets.
you can see in the screenshots, that it is online on both:
V2:

V3:

As i am currently not at home and still don’t have a vpn connection to the home network I have no screenshot of the winbox config of the miktrotik wap.

[vaasseniot]

I’m having the same solution: connected to both - V2 and V3.

[s54mtb]

Is there a working example for configuration on both sides? I was trying to register new gateway on V2 and V3 witgout success. The V2 is OK, but has Status:unknown for the gateway and in V3 I got error: ID taken.

Here is my configuration:

V2 console:

When I change last digit in ID from 0 to 1, I can register new gateway in V3. I changed server to eu1.cloud.thethings.network
but the GW is not connecting…

Is there something I have to configure additionally to the settings described here:
https://help.mikrotik.com/docs/pages/viewpage.action?pageId=8978744#wAPLR8kit-Configuration
or here:
https://www.thethingsnetwork.org/docs/gateways/mikrotik/

???

Or it just takes a very long time to connect?

Meanwhile during my typing some packets arrived:

But the status of the GW is “unknown”.

Should there be some log in the “traffic” for the server connection ?

[descartes (Nick McCloud)]

There is no point registering with two different systems as you can only tell the gateway one place to send the uplinks without getting in to rather advanced settings, v2 & v3 traffic are shared between the two and one will be shut down in the near future.

Have you read the sticky note at the top of the forum about v2 console status?

v3 only shows connected once it see traffic.

Please can you format you post, see this for info:

How do I format my forum post? [HowTo]

The TTN forum is using Discourse, which supports several ways to format your post: Markdown BBCode HTML Any combination of the above Quite often you’ll need an empty line above specific formatting to make it work. You’ll also have to type blank lines to create proper paragraphs; just pressing Return once and then typing a new block of text right below a previous block only creates a so-called line break, which might be harder to read. Leaving one blank line between two blocks of texts nicely…

@descartes

v3 only shows connected once it see traffic.

Hi
Does that mean, my Mikrotik Lora8, laying on my table indoor with no Lora signal around, can’t show connected until an signal is received? For example a not connected temp device…?

tnx for help…

[descartes (Nick McCloud)]

I haven’t retested since new releases of the stack, but I saw my gateways saying not connected even though it was showing stat messages. Once an uplink arrived, it showed as connected.

But you can try this.

@RudiOnTheAir

For example a not connected temp device…?

A LoRaWAN gateway in a forest won’t show connected if the end-device isn’t powered & transmitting.

[RudiOnTheAir]

OK, so there’s a chance that i’ve configured it alright.
For my 1st tests, i’ve an Elsys.se ERSCO2, but that is connnected to another server outside TTN…

[RudiOnTheAir]

Seems not to connect… On my Mikrotik i can see the traffic, but nothing on TTN. Whats wrong. Should i have to use the “eu.mikrotik.thethings.industries” server??

[descartes (Nick McCloud)]

@RudiOnTheAir

Seems not to connect

What seems not to connect?

If the ERSCO2 is not registered on TTS then you won’t get anything more than some rejected traffic.

But your screen shot doesn’t show any stat messages. Your screen shot does show the address for the gateway server.

[RudiOnTheAir]

Damned. Found ist. On my Mikrotik i added .industries, but in TTN there is by default .network… omg…Sorry.
