An implementation of MQTT using CC3200

With the advancements in electronics and communication, the electronic devices are being interconnected to create a controlled environment. The number of devices that are being connected to the Internet is booming day-by-day. However, the existing protocols are verbose and overburden the embedded devices having constrained resources in terms of memory, computational power, battery etc. As a relief, certain light weight protocols such as MQTT, CoAP etc. are being developed especially for the devices that are part of Internet of Things network. In this paper, an implementation of Message Queuing Telemetry Transportation (MQTT) using a CC3200 node has been presented. Wi-Fi is used to establish the wireless Internet access to the node and real time tasking is incorporated by TI-RTOS. Various sleep modes in the CC3200 have been made use of to improve power saving.
