We are the creators of Mongoose - the most popular networking library.
Mongoose supports HTTP, WebSocket, MQTT, CoAP, DNS, mDNS/DNS-SD (local device discovery) - both client and server mode. It works on top of SimpleLink and provides quite rich networking functionality.
Together with the port, we provide a CCS example for MSP432 : https://github.com/cesanta/mongoose/tree/master/examples/MSP432/ccs
We are looking for a feedback, and requests for ports to other devices.
