 7. Each node will receive/send a message if it "sees" at least one device on the network.

+## 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 and set gateway mode.
