This tutorial will explain how to create applications and node devices in TTN and achieve data transmission and reception from devices to the cloud.
Description
Unit LoRaWAN470 is a LoRaWAN communication module launched by M5Stack, suitable for the 470MHz frequency. The module adopts the ASR6501 solution, supporting long-distance communication while featuring ultra-low power consumption and high sensitivity. The module integrates the LoRaWAN protocol stack and uses a serial communication interface (controlled by AT commands). It can be used as a collection node to connect to gateways in large numbers for data collection and management. This module is suitable for long-range, low-power IoT communication applications, such as environmental monitoring node deployment.
