![]() ![]() So now you can upload the code to your ESP32. Run your app from Xcode within a couple seconds you should see the app’s Bluetooth icon change from Disconnected to Connected and the BLE Shield’s LED should illuminate. ![]() Next make sure your iPhone’s Bluetooth is on and your iPhone is connected to your computer. ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The UART-style communication mode makes it a favorite choice for Arduino enthusiasts. You can communicate with HC-05 over serial protocol. ![]() We'll examine the specifications and profiles that form its foundation, and we'll go over how Bluetooth compares to other wireless protocols. Before starting with the project make sure that your HM-10 module is a genuine HM-10 module.There are widely Chinese cloned HM-10 modules available. Plug the USB cord into the Arduino to supply power. HC-05 is a serial Bluetooth Serial port protocol module that is easy to use. This tutorial aims to provide a quick overview of the Bluetooth protocol. Or copy the following code : #include "BluetoothSerial.h" #if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED) #error Bluetooth is not enabled! Please run `make menuconfig` to and enable it #endif BluetoothSerial SerialBT void setup() So thats all the basic explanation of the code. Circuit diagram for connecting Arduino and HM-10 Bluetooth module is very simple as shown below. It is one of the most popular and most frequently used low range communication for data transfer, audio systems, handsfree, computer peripherals etc. The code includes the SoftwareSerial.h library which contains the necessary functions for Bluetooth communication using Arduino. go to File > Examples > BluetoothSerial > SerialtoSerialBT. Bluetooth Communication is a 2.4GHz frequency based RF Communication with a range of approximately 10 meters. ![]()
