Working with MongoDB in C++
Even though Node.JS is the most popular programming language to use with MongoDB, there's no reason you can't use other programming languages - including C++! This video tutorial will use the C++ client library to create a REST API, then create an application that holds information about MarioKart characters.Feb 22, 2021

Turn BLE: Implementing BLE Sensors with MCU Devkits
After having sketched the plan in our first article, this is the first one where we start coding. In this hands-on article, you will understand how to write firmware for a Raspberry Pi Pico (RP2) board try that implements offering sensor data through Bluetooth Low Energy communication.Apr 02, 2024

Me and the Devil BlueZ: Reading BLE sensors from C++
This article is a step-by-step description of the process of writing a C++ application from scratch that reads from a Bluetooth Low Energy sensor using DBus and BlueZ. The resulting app will run in a Raspberry Pi and might be the seed for the collecting station that will upload data to a MongoDB cluster in the Cloud.Mar 18, 2024

Red Mosquitto: Implement a noise sensor with an MQTT client in an ESP32
We write in Rust from scratch the firmware of a noise sensor implemented with an ESP32. We use the neopixel to inform the user about the status of the device. And we make that sensor expose the measurements through MQTT.Mar 18, 2024

Adventures in IoT 5: Me and the Devil Bluez - Part 3
Resources & more episodes → https://mdb.link/iot00005 Jorge completes the first version of the application on this video. He sends DBus messages to connect to the devices, select the characteristic that has to be read, gets the value and transform it into some native type. He uses the producer-consumer concurrency pattern and finally, he writes the code to disconnect from the device and run and test the final result.

Adventures in IoT 4: Me and the Devil Bluez - Part 2
Resources & more episodes → https://mdb.link/iot00004 Time to write some C++ code. Jorge starts by sending simple DBus messages to Bluez to query and set properties. Then, he uses the same technique to start and stop scanning and listens to signals coming from DBus with information about the devices that are discoverable.

Plans and Hardware Selection for a Hands-on Implementation of IoT with MCUs and MongoDB
In the first article of this series, you can learn about the hands-on IoT project that we will be delivering. It discusses the architecture that will be implemented and the step-by-step approach that will be followed to implement it. There is a discussion about the rules of engagement for the project and the tools that will be used. The last section covers a a selection of MCU devkit boards that would be suitable for the project.Nov 27, 2023
