Quick References

As a constant learner, I get to touch upon many ideas in different areas. This category is for me to capture those ideas which I felt people may reference to get ahead of their tasks. Most of the time, I do come back to this section of my blog to remember what I had learnt in the past.

How to use NSSM to run a Python 3 application as a Windows Service in its own Python 3 virtual environment

If you want to run a Python 3 application as a Windows Service, then you are going to love NSSM. Since NSSM handles the life cycle of a Windows Service for our Python 3 application, we can keep it platform agnostic.

Previously, we saw how we can create a Python 3 virtual environment in Windows 10. Given that, let’s see how we can use NSSM to run a Python 3 application as a Windows Service in its own Python 3 virtual environment.

How to write a C# program to communicate with an ESP32 development board via Bluetooth Serial

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.

How to connect to an ESP32 development board via Bluetooth on your Mac

When you are trying to build a ESP32 project that uses Bluetooth to receive from or send data to another device on Mac, you may want to use your Mac to connect to your ESP32 board to test Bluetooth connectivity.

In this case, you will need to first connect your Mac with the ESP32 development board via Bluetooth.

So how can you do that?

In case you need it, this is how to connect to an ESP32 development board via Bluetooth on your Mac.

How to prepare a virtual environment to run a gpiozero based project on Raspbian Stretch

When you use a virtual environment to run your application, you isolate the dependencies in its own container.

In such a situation, you can ensure that your application can run alongside other applications with incompatible dependencies.

Therefore, I always favour the use of virtual environment for running my Python applications.

With this in mind, this is a story about preparing a virtual environment to run a gpiozero based project on Raspbian Stretch.
