Here is the cellular application framework. High-level cellular communication functions are captured in the API and the underlying details are again abstracted. The cellular application framework supports initialization and configuration, data transmission and reception, cellular interface and provisioning, and statistics gathering. The cellular application framework supports two modes of operation – one is where the stack is executed by the Synergy MCU using the NetX Duo™ TCP/IP stack with TLS and MQTT, and the other is where the stack is executed externally on the cellular RF module device using BSD socket protocol.
