 The most commonly used configuration tells the device to take any ESP-NOW packet it receives and output the data over the serial port (UART):

+You can also use LoRa to expand the distances between hops. While ESP-NOW is quick enough to handle a lot of traffic in real-time, LoRa is much slower. For this reason, you must send LoRa data to a buffer and transmit it at standard intervals.
