Arduino Communication

  1. What is a fast but easy way to send different pieces of information simultaneously between two arduinos. What about if it is a one-way transfer?
  2. What are the benefits of using bluetooth to communicate between arduinos?

I think the most robust and easy to implement method will be UART.

  • Simplex or duplex communication (one-direction or two)
  • easy to implement


  • Maximum baud is ~115200

You can think of bluetooth as UART over the air. Bluetooth modules can serve as a transparent, wireless bridge - so the benefit they bring to the table is wireless UART.
