But it is not the only alternative as we have said. These three boards are based on the Arduino Project and have the ability to communicate via bluetooth. To these two plates we must add the BQ Zum Core A non-original Arduino board but based on this project and of Spanish origin. This plate happens to the first Arduino board with bluetooth, called Arduino Bluetooth. The most popular and recent model it's called Arduino 101. Despite this, there are models with bluetooth.
#Wifi vs bluetooth arduino free#
This is because the technology was not born as free as other technologies and not all Arduino projects needed bluetooth, so it was decided relegate this function to shields or expansion boards that do exist and can be connected to any Arduino board and work the same as if it were implemented on the motherboard.

What Arduino boards have Bluetooth?Īs we have said before, not all Arduino boards are bluetooth compatible, rather, not all models have bluetooth built into their board. This system of beacons or beacons makes any smart device collect this type of signals and allow geolocation as well as certain information that could only be obtained with technologies such as 3G connection or with a wireless access point. Recently a new use has been created for devices with Bluetooth technology, this is based in using bluetooth devices as beacons or simple devices that emit a signal every so often. This is something that we have to find either through shields or expansion cards or through specialized models based on the Arduino Project. However, currently there is no model of Arduino UNO that contains bluetooth by default and that any user can use this technology by default. Thus, Arduino + Bluetooth is a most used combination in the technological world. There are many versions of bluetooth, each one improves on the previous one and all offer the same results but in a faster way and with less energy consumption. For all this, bluetooth technology is very present in projects with Arduino, IoT and even in the latest Raspberry Pi models. This technology is present in many mobile devices, from tablets to accessories such as headphones to elements such as smartphones or desktop computers.īluetooth technology as well as wireless connections are important in the Internet of Things, not only because it is a fundamental part but because the variety of devices with Bluetooth makes the network or data mesh between devices more precise and does not depend on so many points of connection. Possibly by now everyone knows bluetooth technology, a wireless technology that allows us to link devices together to send data between them quickly and efficiently no need for a meeting point or a router. 3 What can we do with Arduino + Bluetooth?.If there are, send that information via Bluetooth to the connected device.

In the first if statement, we check if there are bytes being received in the serial port. In the loop(), send and receive data via Bluetooth Serial. SerialBT.begin("ESP32test") //Bluetooth device name loop() By default it’s called ESP32test but you can rename it and give it a unique name. Initialize the Bluetooth serial device and pass as an argument the Bluetooth Device name. In the setup() initialize a serial communication at a baud rate of 115200. Then, create an instance of BluetoothSerial called SerialBT: BluetoothSerial SerialBT setup() #if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED) The next three lines check if Bluetooth is properly enabled.

The code starts by including the BluetoothSerial library. This code establishes a two-way serial Bluetooth communication between two devices.
Serial.println("The device started, now you can pair it with bluetooth!") SerialBT.begin("ESP32test") //Bluetooth device name
#error Bluetooth is not enabled! Please run `make menuconfig` to and enable it and also demonstrate that SerialBT have the same functionalities of a normal Serial
This example creates a bridge between Serial and Classical Bluetooth (SPP) This example code is in the Public Domain (or CC0 licensed, at your option.) Open your Arduino IDE, and go to File > Examples > BluetoothSerial > SerialtoSerialBT.
