Previous posts introduced " MicroPython bluetooth remote control LED between Raspberry Pi Pico W and ESP32-C3, using aioble library " and " BLE examples run on Nano 33 BLE (as Peripheral) and Uno R4 WiFi (as Central) using ArduinoBLE in Arduino Framework ". This video further test how BLE communication between that two approach.

Last post show how to display on SSD1306/SSD1315 OLED with Uno R4 WiFi & Nano 33 BLE using U8g2 library , this post show how to using Adafruit SSD1306 library. Install Adafruit SSD1306 library and dependencies, Adafruit BusIO and Adafruit GFX Library. Connnection, refer to last post . In last post, it's found that the I2C Address of SSD1306/SSD1315 OLED is 0x3C. Open File > Examples > Adafruit SSD1306 > ssd1306_128x64_i2c Change SCREEN_ADDRESS to 0x3C. #define SCREEN_ADDRESS 0x3C //0x3D Then it can run on Uno R4 WiFi & Nano 33 BLE to display on SSD1306/SSD1315 OLED.

This video show displaying on 0.96 inch 128x64 SSD1306/SSD1315 OLED with NoLogo Uno R4 WiFi & Nologo Nano 33 BLE nRF52840 using U8g2 library . Library: Install U8g2 Library in Arduino IDE's Library Manager. Connection: Connection between SSD1306/SSD1315 OLED and Uno R4 WiFi/Nano 33 BLE notice: Uno R4 WiFi operate on 5V Nano 33 BLE operate on 3.3V The operating voltage of my OLED board is 3.3~5V * Check operating voltage of your own OLED board!

This video show steps to install MicroPython on Nologo Nano 33 BLE nRF52840 manually, basically follow the  MicroPython with Arduino page . Notice that to update bootloader and install the Soft Device, you have to make sure Arduino Mbed OS Nano Boards is installed in Board Manager. And select Board of Arduino Mbed OS Nano Boards > Arduino Nano 33 BLE. With MicroPython firmware flashed, you can download and install  Arduino Lab for MicroPython . Arduino Lab for MicroPython is a lightweight editor for MicroPython programs, supporting connection with a board, code upload, file transfer, interactive REPL shell. You can resume Arduino after MicroPython flashed.
