How to set the WiFi protocol to use on ESP32C6?

[aidengk-iris]

Dear all,

I am trying to utilize the WiFi6 support on ESP32C6 (station mode) by setting the protocol to use:

if let Err( set_wifi_protocol_error ) = _wifi_controller.set_protocol(esp_wifi::wifi::Protocol::P802D11BGNAX.into()){
    println!("Failed to set wifi protocol: {:?}", set_wifi_protocol_error)
}

All the other WiFi functions were fine. However, this line to set protocol returned an error "UnknownWifiMode". I'm quite confused, since the ESP32C6 and esp-hal both support WiFi6.

I appreciate any insight to this issue.

Thank you.

Here are the network related dependencies of my project:

esp-hal = { version = "=1.0.0-beta.1", features = ["esp32c6", "unstable"] }

embassy-net = { version = "0.7.0", features = [
  "dhcpv4",
  "medium-ethernet",
  "tcp",
  "udp",
] }

esp-hal-embassy = { version = "0.8.1", features = ["esp32c6"] }

esp-wifi = { version = "0.14.1", features = [
  "builtin-scheduler",
  "esp-alloc",
  "esp32c6",
  "smoltcp",
  "wifi",
] }

smoltcp = { version = "0.12.0", default-features = false, features = [
  "medium-ethernet",
  "multicast",
  "proto-dhcpv4",
  "proto-dns",
  "proto-ipv4",
  "socket-dns",
  "socket-icmp",
  "socket-raw",
  "socket-tcp",
  "socket-udp",
] }

The error might hint that STA mode is not enabled yet so the function "doesn't know" which interface to use. When do you call the function?

You probably want to try to call it after set_configuration or even after start.

On the other hand, I guess we should add a setting in ClientConfiguration (and make sure the protocols get set in set_configuration)

(Unfortunately, I don't own a suitable access-point to really test this myself)

Thank you @bjoernQ ! Indeed, I was able to set the protocol after set_configuration (and before start_async).
