How do the mcus communicate between each other? is there example using i2c or spi or can? no point in buying two mcus and use only one

The MCUs would communicate with each other via WiFi or Bluetooth. I2C, SPI and can are used to communicate with peripherals such as sensors or displays. One could have devices with temperature/humidity sensors at different places in your environment using the on-board display to show the temperature at that location and have the device send the values to a central location periodically.
