I’m stuck now with device registration: Reading the documentation I could use a join server instead of defining a OTAA key. However leaving the OTAA key field blank - I get error:“join-server returned error: response error, code: Other, description: get device-keys error: object does not exist”
So the default join configuration doesn’t work. How can I configure the Join server properly?
Otherwise the device manual (Dragino LSN_50) states that in the OTAA key field the device ID should be filled- but this is definitely wrong as there are not enough bites in the device id. So where do I get the OTAA key from? There is something I can not understand from the docs. But help would be very much appreciated!! Thank you
Hi @vherbst
Chirpstack already provides you a join server in its files. You can enter your code with two keys (by OTAA):
-JoinEUI: (Chirpstack’s Join will manage this key, so you can enter with this zeros: “0000000000000000”)
-AppKey: The one that your application device will generate when you create
with this two keys, you can setup the code in your microcontroler’s IDE
Hope this helps 
for OTAA you need the AppKey from this device, which programmed inside it.

You can, but in that case you must configure an external join-server and this join-server must be aware of your device. In case of doubts, you probably want to set the keys through the ChirpStack web-interface.
