Application note
Firmware update with FOTA, FOAT and EasyFlash
This document introduces you to the flexible and multiple options of firmware (FW) updates with LEXI-R4 and SARA-R4. It covers all FW update options including EasyFlash (our proprietary FW flash tool over UART or USB), the tethered FW update (FOAT), and firmware over the air update (FOTA) via HTTP(S).
Internet applications development guide
This document provides detailed examples of how to use AT commands to develop IP applications in LEXI-R4 and SARA-R4 series modules. It covers data connectivity (PDP context), data security (certificates, TLS, etc.), dial-up network (PPP), TCP/IP internal stack, MQTT client, HTTP client.
This document describes the implementation of the LwM2M client in Trasna LEXI-R4 and SARA-R4 modules.
