Hi @felipejfc, us Adafruit funded folks haven't done ESP-Now stuff. We're happy to help you debug this. The first step I do is with a debug build DEBUG=1 and then see the UART output for ESP-IDF logging. We're available US work hours on Discord: https://adafru.it/discord in #circuitpython-dev

Problem seems to be WiFi 6 mode on the ESP32C6 board. With the debug build I get this extended error message:

W (27220) wifi:This API is not supported in WIFI6 mode, please use esp_now_set_peer_rate_config() instead
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
espidf.IDFError: Generic Failure

Unfortunately, I haven't found a solution or workaround for this till now.

I think the solution is to migrate to esp_now_set_peer_rate_config(). I've asked on the ESP forum what the values for the other parameters (phymode, ersu and dcm) should be so that it is backwards compatible.

Anyone know the parameters to use with the new API?
