ESP32-S3 as bluetooth proxy doesnt work?

I have an esp32-s3 that I cant get working with bt proxy. I can get esp32-c3’s working and regular esp32 generic boards, but no luck with the S3.

I confirmed by using very verbose logs and also downloading the diagnostic data in the device page, it shows that it has seen no bt devices or advertisements. The config is correct and when the board spits out its config, both the bt proxy and ble tracker are configured.

I have found several other posts using esp32-s3 boards and not being able to see any data.

Need to add some of the same sdk options as the c3:

framework:
    type: esp-idf
    sdkconfig_options:
      CONFIG_BT_BLE_50_FEATURES_SUPPORTED: y
      CONFIG_BT_BLE_42_FEATURES_SUPPORTED: y
      CONFIG_ESP_TASK_WDT_TIMEOUT_S: "10"

Dropping this here as I have just gotten this board to work as a bluetooth proxy in HA. Don’t just copy 'n paste, you need to read the documents from your manufacturer. You’re looking for something like this

… in their documentation. This will help you fill out the lines below the type: line in the ethernet segment of the config. I think I might be able to do as fast as 80MHz with the board I have but 30 is working for now so I may leave it.
