title: SPI Display over Bluetooth
body: <p>I want to run an SPI display completely via Bluetooth from a Raspberry Pi 4. I have an ESP32 that can be used for a clock signal, chip select, power, etc. I have them communicating via Bluetooth, but I just do not know how I would send the data over Bluetooth instead of through a pin. I am using the ST7789 driver from <a href="https://pypi.org/project/adafruit-circuitpython-rgb-display/" rel="nofollow noreferrer">this</a> library. I need to know what code I would have to change and/or add to make this work.</p>
  <p>Thanks!</p>
