I apologize for the misunderstanding earlier. Here's the information including the statements for the images:
ESP-NOW is a short-range, low-power communication protocol that allows multiple devices to communicate without the need for or the use of Wi-Fi. This protocol is similar to the low-power 2.4GHz wireless connection commonly found in wireless mice—devices must be paired before they can communicate. Once paired, the connection between devices is continuous, point-to-point, and does not require a handshake protocol.

Displays the device's MAC address, received data, WiFi name, remote host MAC address, and sent data on the screen.
Note: The variable names created cannot be the same as the parameter names, meaning you cannot use names such as "addr" or "data" for variables intended for data retrieval.
Displays the device's MAC address, received data, WiFi name, remote host MAC address, and sent data on the screen. Sets the button to send and stop functionality.
Note: The variable names created cannot be the same as the parameter names, meaning you cannot use "flag" as a variable name for data retrieval.
After completing the program editing, run the receiver and transmitter programs respectively to achieve ESP-NOW short-range wireless communication.
