Description

I am using basic ESPNow examples. When I intentionally test it with different channels,

I do see the following error on my Serial port.
E (21407) ESPNOW: Peer channel is not equal to the home channel, send fail!

This is good information. However, the only response code that comes out is from the following code.

else if (result == ESP_ERR_ESPNOW_ARG) {
Serial.println("Invalid Argument");
}

Which is fine if this would always mean "channel not same". I would like to make use of this information. So, Can you confirm if

1. ESP_ERR_ESPNOW_ARG always means wrong channel
2. Or What is the best way to get the error code for "ESPNOW: Peer channel is not equal to the home channel" inside the code.

I went through https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/error-codes.html, but no specific error code that I can find to this effect.

thanks,
