ESP-NOW is a kind of connectionless Wi-Fi communication protocol that is defined by Espressif. In ESP-NOW, application data is encapsulated in a vendor-specific action frame and then transmitted from one Wi-Fi device to another without connection. CircuitPython espnow module provides an interface to the ESP-NOW protocol. It's exercises of CircuitPython espnow to communicate between sender ( Waveshare ESP32-S3-Zero / Seeed Studio XIAO ESP32C3 ) and receiver ( Espressif ESP32-S3-DevKitC-1 ). In the receiver side, the receiver message are display on ILI9341 SPI LCD. For the setting of using ILI9341 SPI LCD, read  3.2" 320x240 IPS LCD (ILI9341 SPI) with Cap. Touch (FT6336) and Micro SD Slot on ESP32-S3/CircuitPython 9.0.3 . Exercise Code: cpyS3_ili9341_espnow_receiver.py , run on Espressif ESP32-S3-DevKitC-1 and display on ILI9341 SPI LCD.

Last post show ESP32-S3 running CircuitPython 9.0.3 to display on ILI9341 SPI LCD, detect FT6336 Cap. Touch, and load bmp from SD card using adafruit_imageload . The post show exercise to download bmp images from internet and display on ILI9341 SPI LCD. Basically, the network part follow the CircuitPython  adafruit_imageload example imageload_from_web.py . In the original example, bmp file is downloaded from https://raw.githubusercontent.com/adafruit/Adafruit_CircuitPython_ImageLoad/main/examples/images/4bit.bmp . In this exercise, my own Python http server was setup on Raspberry Pi 5/64-bit Raspberry Pi OS (bookworm), to store my bmp images. Enter the command in Terminal: python3 -m http.server Or save it in a executable shell script as shown in the video.
