PMOD Expansion Board for RYZ024A

AI 生成的摘要: This guide explains how to connect the RL78/G23-128p Fast Prototyping Board with a cellular IoT module to Amazon Web Services (AWS) using FreeRTOS. It includes two demo projects: PubSub for MQTT data communication and OTA for firmware updates over the air. The document details hardware and software setup, including pin configurations, project structures, and AWS IoT connection settings. It also covers the end-of-life replacement of the RYZ024A LTE module with the Sequans GM02S module. Users learn how to build, run, and debug the demos, configure AWS services, and perform firmware programming and updates.

AI 生成的摘要: The document explains how to implement LTE Cat M1/NB1/NB2 communication using RL78/G22 as the host MCU and RYZ024A as the cellular module controlled via UART and AT commands. It details an MQTT communication sample application that supports Publish/Subscribe operations, power-saving features like eDRX and PSM, and an AT command management framework. The software architecture, peripheral usage, and low power operation methods are described. It also covers specific handling for the PMOD-RYZ024A expansion board and provides related references for further integration and development.

AI 生成的摘要: RYZ024 modules operate in four power states—Deep Sleep, Sleep, Active Standby, and Modem Active—each with distinct wake-up latencies. Power-saving protocols eDRX and PSM optimize battery life by controlling UE paging and sleep cycles. eDRX allows the device to monitor paging only during specific intervals, enabling deep sleep between cycles, while PSM extends sleep duration by managing timers for idle and tracking area updates. Power measurement setups require specific hardware, including a power analyzer with microamp accuracy, and detailed modem configuration steps ensure accurate power consumption evaluation under various network conditions.
