I was a little confused In Exempla OTA, in order to connect to the initiator, both devices must be connected to an access point, or it is enough for the initiator to download the file and then send it to the devices via Broadcast or Unicast.

@mrdsn3 The responder devices may not connect to an access point, but should be at the same channel with initiator. Because initiator connects to an AP and can only send esp-now in the AP channel. You can set the channel of the access point to channel 1, or set responder device channel to the AP channel(by esp_wifi_set_channel()).
