[Documentation] How can I get response data with chip-tool command?

Documentation issues

Hi, Is there a guidance document on how to use chip-tool command or API to get response data in a readable format?

Platform

No response

Anything else?

No response

It depends on what you mean by "readable".

If you just want the command payloads, see the https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/chip_tool_guide.md#using-message-tracing

If you want to see something else... chances are chip-tool is not set up for it. It will log things like command responses and attribute read/subscribe results, for cases when it knows the schema to parse as, and it can log incoming TLV, but that's it.

So what exactly are you trying to do?

Hi @bzbarsky-apple , I want to parser the chip-tool response data to JSON and send it to the Cloud. If the data is in the log, it is useless for our actual application. Is there any other way?

@lancersky2017 I believe chip-tool interactive server lets you start a chip-tool that you can then connect to via websocket to send it JSON commands and get JSON responses. I don't know that this is documented particularly well, though. @vivien-apple would know for sure.

Need to update to the latest version.

@vivien-apple @bzbarsky-apple My Websocket client doesn't receive messages for subscribe command. Is it true that the subscription messages are sent viva WebSocket?

@nmtoan91 I dont know.
