Can ESP32 run WiFi and Bluetooth at the same time?
Bluetooth and WiFi work perfectly well together. There is no reason why they can’t share the antenna. They also share the 2.4GHz consumer band, but seem to co-exist quite happily in one or two of the applications I have written.
Do all ESP32 have Bluetooth?
The ESP32 comes not only with Wi-Fi but also with Bluetooth and Bluetooth Low Energy (BLE). This post is a quick introduction to BLE with the ESP32.
How do you use Bluetooth on ESP32?
Make sure you have the right board and COM port selected. After uploading the code, open the Serial Monitor at a baud rate of 115200. Press the ESP32 Enable button. After a few seconds, you should get a message saying: “The device started, now you can pair it with bluetooth!”.
How much devices can connect to Bluetooth?
Bluetooth-equipped smartphones and laptops can connect to multiple devices at once. The latest Bluetooth 5 specification allows up to 7 device connections simultaneously to a primary device in active mode. Some Bluetooth accessories may use the same Bluetooth profile or functionality, which may conflict.
How do I add Bluetooth code to ESP32?
Uploading the Code and Testing Now, turn on Bluetooth in your smart phone and scan for Bluetooth devices. You should see a list of ‘Paired devices’ and ‘Available devices’ and from the available devices, select ‘ESP32’. Your mobile will ask if you want to pair with ‘ESP32’ and you select yes (or ok).
Can two Bluetooth devices be connected at the same time?
Thankfully, with Bluetooth multipoint, you don’t have to. Simply put, Bluetooth multipoint gives you the ability to pair two different Bluetooth sources—like your smartphone and laptop—to a compatible headphone, both at the same time. Then put the headphones in pairing mode again and connect your second device.
Why are there two types of Bluetooth in ESP32?
But it turns out that, Bluetooth Low Energy (BLE) is not indented for that. I also discovered that there are two types of Bluetooth in the ESP32 module, one is the Classic Bluetooth and the other is BLE Bluetooth Low Energy. Okay, but why?…. why do we have two types of Bluetooth and what should I use for my project?
What do I need to know about ESP32 ble?
In later articles we will cover ESP32 BLE as server as well as client. BLE server is generally used to send BLE data to other Bluetooth Devices and BLE client is used to scan other BLE devices thus act as beacon.
Which is the main feature of the ESP32 SoC?
We know that the main feature of ESP32 is Wi-Fi. But additionally, the ESP32 SoC also has Bluetooth support as well. ESP32 Bluetooth is a dual-mode system. This means ESP32 supports both Classic Bluetooth as well as Bluetooth Low Energy (BLE).
How is data sent between Bluetooth and BLE?
In classic Bluetooth, the serial port protocol (SPP) is usually used to send data between the devices as the communication occurs without much overhead, but for BLE, data during communication is organized using a profile referred to as GATT (Generic Attributes).
