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.

Adventures in IoT EP2: Turn on BLE (Bluetooth Low Energy)
In this episode, Jorge covers some relevant Bluetooth Low Energy concepts and puts them in practice by using them in writing the firmware of a Raspberry Pi Pico board. In this firmware, we use the on-board LED, read from the on-board temperature sensor and implement a BLE peripheral that offered two services and a characteristic that depended on measured data and could push notifications. ✅ Sign-up for a free cluster at → https://mdb.link/free-vXFjpScH8AQ ✅ Get help on our Community Forums → https://mdb.link/community-vXFjpScH8AQ Adventures in IoT playlist → https://trymongodb.com/3R38iGX Subscribe to MongoDB YouTube → https://mdb.link/subscribe

Adventures in IoT EP1: Project Intro
Resources → https://mdb.link/iot00001 In the first episode of this series, Jorge introduces the project that we will be developing. It will be a series of sensors that gather noise data that will be collected by a bespoke implementation of a collecting station. We will explore two mechanisms for the communication between the sensors and the collecting station: BLE and MQTT over WiFi. Once the data is in the collecting station, we will send it to a MongoDB Atlas cluster on the Cloud using the C++ driver and we will finish the project by showing some potential usages of the data in the Cloud. Jorge also presents a list of requirements for the development boards and some alternatives that match those requirements and you can use for this or similar projects. ✅ Sign-up for a free cluster at → https://mdb.link/free-FW8n8IcEwTM ✅ Get help on our Community Forums → https://mdb.link/community-FW8n8IcEwTM Adventures in IoT playlist → https://trymongodb.com/3R38iGX Subscribe to MongoDB YouTube → https://mdb.link/subscribe

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.
