Connecting LoraWAN to TTNv3 error MIC mismatch

rojikada opened this issue 3 years ago · 8 comments

Hello, does anybody have this working with the TTNv3? I am trying to use the lorawan module with TTNv3, however in the TTN console I get MIC mismatch.
The appEui = appEUI, DevEUI=devEui, JoinEUI=appKey and the specifiation is LoRaWAN 1.0.2 ?

Aha! The problem was in having all zeroes in appEUI, after recreating the app with non-zero appEUI it started to work!

Hi @rojikada , where did you get the the appEUI , devEUI and JoinEUI -> Did you generate from your own? Thanks.

I just changed it within my code and the TTN web

I see the JOINEUI is not available from the TTN, but another key can be generated. So can we use a random for that and match the same with the node firmware?

I don’t understand what are you trying to do.

And as stated previously JoinEUI=appKey, which worked for me.

Sorry for the confusion, I mean: When we register a new node in TTN, we need to provide the JoinEUI, so for a DIY project where do we get the JoinEUI if the manufacture did provide it with all? Thanks.

You just generate one and put it to your code setup. If the device is not programmable, you might be on the wrong page.

Got it, Thanks for your time. 🙂

I use the http://descartes.co.uk/CreateEUIKey.html to generate the EUI key.
