Cannot start wifi on esp32s3 #2364

Closed akesser closed 1 month ago

akesser commented 1 month ago

Bug description

I am trying to run the wifi examples on a esps3, but the code stops at Device capabilities: Ok(EnumSet(Client)) Starting wifi

The chip is getting hot and can't be flashed after a reboot.

Thanks for your help in advance!

To Reproduce

export SSID="myssid" export PASSWORD="ChangeMe" cargo xtask run-example esp-hal esp32s3 wifi_embassy_dhcp

Expected behavior

The chip should be able to start the wifi and continue the script

Environment

It's probably working, it's most likely that you have the USB port plugged into the usb-serial-jtag port, which WiFi automatically disables for better RF performance. We have a feature to keep it enabled, could you try enabling phy-enable-usb feature and trying again?

Thanks for the hint! It works now. I spend a pull request to add a note to all the wifi examples.
