+5. There are no periodic/synchronous messages on the network. All devices are in "silent mode" and do not "hum" into the air.
 6. Each node has its own independent routing table, updated only as needed.
 7. Each node will receive/send a message if it "sees" at least one device on the network.
 8. The number of devices on the network and the area of use is not limited (hypothetically). :-)

 ## Notes
 
 1. Possibility uses WiFi AP or STA modes at the same time with ESP-NOW using the standard libraries.
-2. For correct work at ESP-NOW + STA mode your WiFi router must be set on channel 1.
