matter-rs's Issues

PAKE: Handle retransmissions better

Commissioning fails on Linux

Hi all!
I really appreciate your work on this crate; The functionality that is already implemented looks quite promising to me!
Unfortunately, I was not yet able to commission the example as described in the README because the CHIP tool crashes. Here is an extract of the log:

The Rust example itself logs two error messages:

[2022-09-12T07:22:53Z ERROR matter::sys::sys_linux] Linux is not yet supported for MDNS Service

[2022-09-12T07:22:59Z ERROR matter::secure_channel::core] PASE Not enabled

From briefly looking at the code, I assume that you are working on MacOS? I am on Ubuntu 22.04, so this may be part of the problem. For testing purpose, I added an MDNS implementation for sys_publish_service() to sys/sys_linux.rs. However, the second error remained, so I suppose this is the actual problem. Could you give me some hints?

Thanks four your help!
Regards :)

Feature Request: Separate the Matter TLV into its own crate

I prefer if we could split things such as the Matter TLV into its crate.

Use ring on esp-idf platform

We don't have support for rust-mbedtls on the esp-idf platform yet, but perhaps ring can help. We have a fork here: https://github.com/esp-rs-compat/ring with the required patches. Any rust crypto library that uses ring should be available with this patched dependency.
