The AE-CLOUD2 kit together with the Synergy Software Package (SSP) version 1.5.0 simplifies connecting IoT sensor devices to enterprise cloud services using 4G/LTE Cat-M1 and Cat-NB1, also know as NB-IoT, with fallback to 2G/EGPRS cellular networks. SSP 1.5 provides customizable production grade software using: ThreadX® real-time-operating system (RTOS); NetX Duo™ Message Queue Telemetry Transport (MQTT); NetX Secure™ Transport Layer Security (TLS 1.0, 1.1, 1.2) for secure communications with cloud services; support for HTTPS Client and HTTP 1.1 Client; wireless Frameworks for connecting to LTE IoT networks and cloud services; the SSP Cellular Framework provides APIs to provision, configure and communicate with cellular networks for data communication. Example projects for Amazon, Microsoft, Google, and Medium One, including reference code and instructions for connecting AE-CLOUD2 to each cloud service using Ethernet, Wi-Fi, or LTE IoT cellular are available.
