Coupled with Bluetooth Serial and GPIO pins, ESP32 can augment a Windows machine with the ability to read from sensors.
So with an ESP32 development board, you can turn your old Windows machine into an IOT gateway that can sense its operating environment.
Given these points, let us look at how we can write a C# program to communicate with an ESP32 development board via Bluetooth Serial.
When you have an old Windows 10 machine, you can reuse it as an IOT gateway.
Given that your Windows 10 machine has working Bluetooth, you can connect it to an ESP32 development board.
In case you need a reference to connect to an ESP32 development board via Bluetooth on Windows 10, here are the steps to do so.
Since a ESP32 development board comes with Bluetooth, we can get it to communicate with another device over Bluetooth Serial.
With this in mind, let’s look at how we can get your ESP32 development board to communicate with another device over Bluetooth Serial.
