example code is not working with qemu networking #68

Closed mike1703 closed 2 years ago

mike1703 commented 2 years ago

I have issues with running the example code on qemu and have working networking.

one issue is that code apparently was copied from the wifi section here and produces this error

error[E0425]: cannot find value `wifi` in this scope
    --> src/main.rs:1272:5
     |
1272 |     wifi.wait_status_with_timeout(Duration::from_secs(10), |status| !status.is_transitional())
     |     ^^^^ not found in this scope

this can be fixed by including use embedded_svc::eth::TransitionalState; and replacing wifi with eth

But then the code seems to have problems in receiving an IP when starting with qemu.sh (therefor started with qemu-system-xtensa -nographic -machine esp32 -nic user,model=open_eth,id=lo0,hostfwd=tcp:127.0.0.1:7888-:80 -drive ...).

As the code itself had to be patched it does not look like it was tested yet. Is there an issue with the code itself, with the qemu command (network options) or potentially something wrong with my system?

I can get better results If I'm using the following line in .cargo/config.toml ESP_IDF_VERSION = { value = "release/v4.4" }

Sorry about the copy-pasted code. This occurred with the last commit, as the API of wifi (and eth) changed, and I had to update it, yet I neither compiled, nor tested with eth enabled.

I would gladly accept a PR for this.

As for the second issue, as you have noticed, QEMU only works with V4.4 (used to be master) and should work with 5.0 (= master) but I haven't tested the latter. As the instructions mention: export ESP_IDF_VERSION=master; cargo build --features native,qemu

I'll keep this issue open until the copy-paste is fixed & merged. And will probably update the README to also mention version release/4.4.
