I’m not sure if this is the correct location for this post. I’ve also posted on Espressif.
I’m using the ESP8266 with Arduino core on platformIO.
I’m using ESP-NOW in controller mode. WiFi set to station mode.
ESP initiates fine and sets the role fine.
When I try to add a peer using the receiver’s MAC address I’m finding that it will fail with a return value of -3.
esp_now_add_peer(receiversMAC, ESP_NOW_ROLE_SLAVE, _channelValue, NULL, 0);
However this only happens with certain addresses e.g. 126.96.36.199.55.66 (hex).
As the receiver is using soft AP so I can set the receiver address as required.
As anyone experienced this? Kind regards,
