I would like to find an Arduino with built-in Bluetooth. I know about the HC-06, the shields and the other Bluetooth modules, but i would like to have built in Bluetooth for eliminating the risk for miscommunication on the serial port.

The official Arduino foundation did produce an board but it's retired now.

  • By the way, how could miscommunication on a Bluetooth shield be any different from miscommunication on an integrated Bluetooth for a board?

    Yeah i know what google is. Why it would be better? Less moving parts, well tested board. If you think its an dumb question dont answer then. There are plenty of other post waiting for your knowledge.

    @Sigma - If a board becomes a moving part, you need to check your soldering :D

    What about using an ESP32 with integrated BT?

Arduino has just released a MKR WIFI 1010 board that includes an ESP32 module that allows Bluetooth connectivity. It's mainly an internet of things board but it supports:

  • Bluetooth low energy, BLE
  • Wifi

There is this board called Bluno Its an Arduino UNO Based board with built in Bluetooth 4.0

This is my currently favourite Arduino compatible board: https://wiki.wemos.cc/products:d32:d32

ESP32 is great: offers both wi-fi, Bluetooth and BLE connection as well as lots of GPIO. 9 GPIO's can be used as capacitive touch sensors (it has 10, but only 9 are available).
