MIC Mismatch error over-and-over while redoing TTN Amsterdam Workshop follow-up #246

Closed BRUNO7878 closed 1 year ago

BRUNO7878 commented 1 year ago

Hi Orkhan,

Summary: I try to redo the TTN Amsterdam workshop on connecting the generic node to the TTIG gateway Unfortunately I get "MIC mismatch" error is generated.

Steps to Reproduce:

  1. Create TTS cloud account

  2. Set up the gateway TTIG868 ( this seems to work as I see it in the console

  3. Add Application in the console

  4. Add Device in the application ( QR code does not work => Manual )

  5. Missing the exact set up ( as described in the workshop of Friday ) The observed the MIC Mismatch End device set up

  6. ...

What do you see now? { "name": "ns.up.join.cluster.fail", "time": "2022-09-25T14:11:48.996779017Z", "identifiers": [ { "device_ids": { "device_id": "eui-0004a310001ab086", "application_ids": { "application_id": "my-cellar-conditions" }, "dev_eui": "0004A310001AB086", "join_eui": "70B3D57ED0000000" } } ], "data": { "@type": "type.googleapis.com/ttn.lorawan.v3.ErrorDetails", "namespace": "pkg/joinserver", "name": "mic_mismatch", "message_format": "MIC mismatch", "correlation_id": "0bd7bf72259542f49025b4279cbab2f4", "code": 3 }, "correlation_ids": [ "ns:uplink:01GDTFTV3TNSNYA59KMRME0WJB", "pba:conn:up:01GCVC8DZ97A0SDB61H0E8QFZ4", "pba:uplink:01GDTFTV3Q4XFTN6VB9X27Y9XN", "rpc:/ttn.lorawan.v3.GsNs/HandleUplink:01GDTFTV3TG27N3314826FTF0E" ], "origin": "ip-10-23-6-193.eu-west-1.compute.internal", "context": { "tenant-id": "CgRnbnNl" }, "visibility": { "rights": [ "RIGHT_APPLICATION_TRAFFIC_READ" ] }, "unique_id": "01GDTFTV44KDTQC9XZ09DW2MZ4" }

Environment: Set up on MAC book pro, Following training guide lines

...

What can you do yourself and what do you need help with? Is its mandatory to make a device claim ? If so where is this explained ? What is a tenant ? Do you have a more complete slide deck to explain the steps ( without QR code ) to have the "plain vanilla" set-up connected to a private gateway ?? There is no YouTube video showing a successful step-by-step genericnode connection . When would this one be published ? Instead the is a long traning about hardware and FW dev . Note : that the AppEUI provided on the Generic node is 1 char too short vs what the console is expecting . After several trials and errors Have been looking at the training slide deck => I guessed from slide 16 it was to append a "0" at the end.

Thank you for your support
