Application Protocols

Application Protocol libraries provide connectivity for building microcontroller-based IoT devices. The 'core' branded application protocols are 'standalone' in that they do not have any dependencies outside of the C library. They use a simple transport interface definition to ensure they are not dependent on the underlying TCP/IP stack.

coreMQTT

A lightweight pub/sub protocol for IoT use cases.
Source code is now available in coreMQTT github repository.

coreHTTP

A lightweight request and response messaging protocol for IoT use cases.
Source code is now available in coreHTTP github respository.

coreSNTP

The coreSNTP library provides a client for the Simple Network Time Protocol (SNTP) to allow devices to synchronize their system clocks with time servers. This library implements the SNTPv4 specification defined in RFC 4330.
Source code is now available in coreSNTP github repository.
