@TimoRoth Theoretically yes, since ESP-NOW is using Vendor Action Frames which are management frames that can be transmitted/received in parallel to an association a station has to an AP.

However, the implementation does not support it at the moment. The reason is that each module has its own WiFi initialization. While `esp_wifi` initializes the WiFi interface in Station mode, `esp-now` has to operate in in SoftAP+Station mode. So, one prerequisite will be to find a common initialization. You will already find an according comment int `esp_now_setup`.

Trying `esp_wif` in parallel to `esp_now` is the next item on my todo list. At the moment, it is a bit difficult to work on different drivers and merge them together since the dependencies increase and PRs are pending long time.

If it is possible to use `esp_wifi` and `esp_now` in parallel, you would have two netifs so that one ESP node could act as a border router without having an Ethernet interface.
