SARA-R4/SARA-R5: Guía de Desarrollo de Aplicaciones de Internet

Introducción

Este documento proporciona orientación para el uso de aplicaciones IP en los módulos SARA-R4 y SARA-R5. Incluye ejemplos de comandos AT para interactuar con los módulos celulares u-blox para la conectividad de red y el uso de protocolos IP. Cubre aplicaciones que dependen de la pila IP, como sockets, MQTT, MQTT-SN, HTTP, FTP, CoAP y SSL/TLS.

La primera parte describe la conexión de datos de paquetes conmutados (PS), incluyendo la definición del contexto y el procedimiento para obtener una dirección IP válida de la red. La segunda parte proporciona información sobre aspectos de seguridad útiles para gestionar y configurar una conexión de datos segura.

Para obtener más detalles sobre la documentación disponible para los módulos celulares u-blox, consulte la guía de desarrollo de aplicaciones de notas de aplicación [8], [11].
