Example wifi_embassy_dhcp not working

[DBLouis]

I tried running the wifi_embassy_dhcp example on my ESP32 without success. The other example wifi_dhcp work correctly.
I just cloned this repository and run the example as-is, changing only the SSID and PASSWORD environment variables.

This is the output I get in serial connection:

Hmm, works on my esp32 🤔
One difference I see from the log is the chip revision, let me check if I have an access to the v1.0 board.

UPD: Also try to reset the chip couple of times, I've had this happen multiple times and it helped 😄 .

Works for me on esp32 v1.0 board as well

@DBLouis Let us know how it goes when you get to it, please 😉

I tried again, let it run longer, and restarted several time. It run the example with this command: cargo xtask run-example esp-hal esp32 wifi_embassy_dhcp.

Also my board is ESP-32 Dev Kit C V4.

Never mind, it works fine. I was using an AP with WIFI AC, which is not supported by the chip. WIFI N works fine of course.
