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.Sep 04, 2024 | 25 min read

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

MongoDB for IoT → https://mdb.link/iot-L8doXUhiOuw In this episode, Jorge shares how to use the command line of a Raspberry Pi OS system to interact with Bluetooth Low Energy and then how this achieved using DBus. We will use this knowledge in the next episode to drive our C++ implementation.
