Use the ESP32 as a serial gateway (Bluetooth to Serial or Wifi Httpserver to serial) to connect a phone or tablet on any serial device (SPI, I2c,...).
Use the ESP32 as a webserver on Wifi (access-point or client) or bluetooth interface to access any serial device using protocol supported by ESP32 from a tablet, phone or laptop.
