Gateway frames stream
Closed this issue · 4 comments
- The issue is present in the latest release.
- I have searched the issues of this repository and believe that this is not a duplicate.
What happened?
When trying to stream frames from /api/gateways/{gateway_id}/frames we don't get any data.
What did you expect?
Getting join request via the stream. I'm faily confident things are setup correctly as I get an error if I use the wrong api key.
Steps to reproduce this issue
Steps:
- Add device to chirpstack
- Start streaming from /api/gateways/{gateway_id}/frames
- Send join request from device
- Wait from data on the stream.

Stream API not work from any browser see attached screenshot for your reference
You need to create a web-socket connection for stream APIs.
Thanks for the fast reply.
I already saw that note in the docs. I'm interfacing the API from C# with a RestClient. It works fine for all other things and I hoped it would work for the streams also - but maybe not ?
@KrestenHelstrup the same applies when using a REST client. My advice would be to use the gRPC interface. The REST interface works as a proxy to the gRPC interface, thus when making a REST call there is an internal translation to a gRPC call:
REST client -> REST API -> gRCP
In order to support the streaming gRPC methods, these endpoints are wrapped in WebSockets. These layers were added to support the web-interface, as by then gRPC was not supported in the browser. This is now supported (through gRPC-web) and probably this translation layer is going to be removed in the next version (probably it could still be provided as external component).
It should be fairly easy to generate C# gRPC stubs from the proto files (https://grpc.io/docs/languages/csharp/quickstart/) and then the streaming of data should work out-of-the box :-)
Hi @brocaar
Thank you very much for the input.
