Heltec LoRa 32 V3 with Meshtastic

Good day everyone, In today's program, we would like to introduce an open-source project that has gained immense popularity abroad - Meshtastic. This project is a device that connects to your mobile phone through various modes, including Bluetooth, and facilitates an interactive operation between the phone and the device. It uses LoRa for low power long-distance transmission, and the devices can form a mesh network that enables multiple devices to communicate with each other. Now let's dive into the details of its operation. We will be using the Heltec LoRa32 development board that comes with Wi-Fi, Bluetooth, and LoRa modules integrated. First, we need to visit Meshtastic's official website and select the model. We recommend choosing version 2.2.17. After that, we can start downloading the necessary files. Once downloaded, we need to select the serial port and click download. Next, we need to open Meshtastic on our mobile phone, configure Bluetooth connection, and start communicating. Meshtastic is highly versatile as it allows unlimited customizations as it is connected to the mobile phone. Along with text information, it can also transmit GPS and sensor data format. After our testing, we found that Meshtastic's communication distance can reach up to 3km. If you are interested in more advanced options, you can always choose the Tracker development board that comes with a GPS module. It not only facilitates communication with the group of devices through LoRa but also provides real-time GPS positioning. You can also select more modules to achieve even more functions. That's all the content about the open-source project of mesh. Thank you for watching!
