When I use lorawan gateway to connect my chirpstack, and by using MQTT BOX to publish date , but I don’t know how to acquire the application id,
application/[ApplicationID]/device/[DevEUI]/command/downIn the doc, it says that " TheApplicationIDcan be retrieved using the API or from the web-interface, this is not theAppEUI` !
but how to get it? Could you please help me ?
Thank you very much!
Log into your chirpstack web-interface at http://blah:8080 and navigate to any of your devices. Then, look at the ADDRESS line of your browser, just after “applications/”.
For me, using Opera, that’s:
http://10.1.6.90:8080/#/organizations/1/applications/5/devices/0025ca0a000001e9
Your number will depend on how many times you’ve clicked “CREATE” in Application page.
I didn’t find this very intuitive either - that’s saying something as I grew up on and still use vi as editor of choice 
See my other ‘discoveries’ on this very topic HERE.
Thank you very much for your reply, and I can’t find the application too, maybe my chirpstack version is too old? My screen is list below, please help me to check it whether
it is correct, thank you again!
http://127.0.0.1:8080/admin#/devices/edit/1234567890987654
So, the address line does not appear the applications sign, so could you please help me again? By the way, I use the GitHub - gotthardp/lorawan-server: Compact server for private LoRaWAN networks version for lorawan test, it seems too old for this .Thank you!
If you move to ChirpStack, I may be able to help. Unfortunately, for me ChirpStack is only a small “cog” in a larger SCADA system I administer.
I selected ChirpStack specifically to migrate existing sensors from TTN when they “lost their way” and made V3 too darn difficult for mere humans to comprehend. For comparison, it took me ~1 day to register 4 gateways and 50-60 sensors on V2, but I spent one solid Saturday trying to register one Laird RG191 gateway on TTI V3 stack and made ZERO progress. Then TTN disabled adding sensors & gateways to V2 in June, so I decided that day to dump TTN entirely and move my sensors to intranet ChirpStack. I’m glad I did.
Hi fmgst,
Thank you anyway, and I just use the Chirpstack, my screenshot is just the chirpstack’s dash board controller screen, I doubt my version is too old, so I decide to change it to a higher version, then I will try it, thank you very much for your kind help ,thank you!
