ESP32C6 Wifi APIs not available on v5.1/v5.1.1

[sjames]

Hi,

I'm using cargo generate esp-rs/esp-idf-template cargo to generate a new esp32 project. I'm using an esp32c6 module, so I use IDF v5.1.1 .

I find that the Rust Wifi APIs defined in src/wifi.rs are not available. The wifi module is gated by the following configurations.

#[cfg(all(
    not(esp32h2),
    feature = "alloc",
    esp_idf_comp_esp_wifi_enabled,
    esp_idf_comp_esp_event_enabled,
))]
pub mod wifi;

I couldn't figure out how these configurations are set. Does anyone have Wifi working with Rust on ESP32C6?

Regards,
Sojan

Answering this myself.

It turns out that the esp-idf-template does not configure the MCU that needs to build, and the default mcu is the esp32h2 that does not have the Wifi.

I fixed this by setting the mcu in the .cargo/config.toml

[env]
# Note: these variables are not used when using pio builder (`cargo build --features pio`)
ESP_IDF_VERSION = "v5.1.1"
MCU = "esp32c6"

I'm in the process of updating the esp-idf-template crate to work with the newly released esp-idf-* crates.
Thanks for this feedback - makes sense! Just updated the .cargo/config.toml with the MCU parameter: esp-rs/esp-idf-template@6d71a63

A new esp-idf-template will be pushed till the end of the week.
