We’ll be using the ESP32 DOIT DEVKIT V1 Board. To follow this example, you need two ESP32 development boards. We’ll use and explain the examples that come with the BLE library. Note: to see the ESP32 examples, you must have the ESP32 board selected on Tools > Board.įor a brief introduction to the ESP32 with BLE on the Arduino IDE, we’ll create an ESP32 BLE server, and then an ESP32 BLE scanner to find that server. In your Arduino IDE, you can go to File > Examples > ESP32 BLE Arduino and explore the examples that come with the BLE library. Mac and Linux instructions – ESP32 Board in Arduino IDE.Windows instructions – ESP32 Board in Arduino IDE.Follow one of the next tutorials to prepare your Arduino IDE to work with the ESP32, if you haven’t already. Note: You need to have the ESP32 add-on installed on the Arduino IDE.

This library comes installed by default when you install the ESP32 on the Arduino IDE. There are several BLE examples for the ESP32 in the ESP32 BLE library for Arduino IDE. The ESP32 can act as a BLE server or as a BLE client. For example, it can identify a particular service provided by a Bluetooth device. In summary, the UUID is used for uniquely identifying information.

There are shortened UUIDs for all types, services, and profiles specified in the SIG (Bluetooth Special Interest Group).īut if your application needs its own UUID, you can generate it using this UUID generator website. An UUID is a unique 128-bit (16 bytes) number. Basically, it contains the operations and procedures that can be used with the characteristic:Įach service, characteristic and descriptor have an UUID (Universally Unique Identifier). The properties describe how the characteristic value can be interacted with. The characteristic always has two attributes: characteristic declaration (that provides metadata about the data) and the characteristic value.Īdditionally, the characteristic value can be followed by descriptors, which further expand on the metadata contained in the characteristic declaration. The characteristic is always owned by a service, and it is where the actual data is contained in the hierarchy (value). BLE consumes approximately 100x less power than Bluetooth (depending on the use case). Unlike Bluetooth that is always on, BLE remains in sleep mode constantly except for when a connection is initiated. BLE’s primary application is short distance transmission of small amounts of data (low bandwidth).
What is Bluetooth Low Energy?īluetooth Low Energy, BLE for short, is a power-conserving variant of Bluetooth.

Recommended reading: learn how to use ESP32 Bluetooth Classic with Arduino IDE to exchange data between an ESP32 and an Android smartphone. Introducing Bluetooth Low Energyįor a quick introduction to BLE, you can watch the video below, or you can scroll down for a written explanation. For a simple introduction we’ll create an ESP32 BLE server, and an ESP32 BLE scanner to find that server. First, we’ll explore what’s BLE and what it can be used for, and then we’ll take a look at some examples with the ESP32 using Arduino IDE. This post is a quick introduction to BLE with the ESP32. The 2M PHY mode is only activated when the 2M PHY request comes from the peripheral (control).The ESP32 comes not only with Wi-Fi but also with Bluetooth and Bluetooth Low Energy (BLE). Unfortunately, I can't find anything comparable under Windows. In our Android App we control this by calling the following method: However, we do not find any way to define the 2M PHY data transfer mode supported from BLE 5.0 as the preferred data transfer mode. The bluetooth discovery service as well as the communication work without any problems. The USB adapter is recognized by Windows and uses the Generic Bluetooth Adapter driver.
