Hello Carles, to work IoT you can use the D1 R2 ESP32 card , this card works with classic Bluetooth, BLE, WiFi ... and can be programmed with the Arduino IDE, you can find it for about € 5.
Here are some examples:
Hello friends,
I'll write in this topic about BLE on ESP32, send and receive text, with clock and without clock. Notify. I'll use the codes of Neil Kolban .

Hello friends,
In this topic I am going to show some examples of Arduino UNO with the Bluetooth HC-06 module.
I will start with simple examples and later I will put some more complicated codes.
