[Background] During the discussion of a control command, we proposed to use the SOME/IP protocol, but the other party suddenly suggested using the MQTT protocol for transmission. This proposal was something we had not encountered before, which left us a bit confused. Therefore, classmate Jiahui conducted an investigation and comparison of the two protocols and … Read more
This post is from a handsome young graduate from Beijing in 2017 – Xiao Xiao Su. 1. Concept MQTT is an IoT communication protocol based on the Publish/Subscribe model. With its simplicity, support for QoS, and small message size, it occupies a significant share of IoT protocols. MQTT (Message Queuing Telemetry Transport) is a “lightweight” … Read more
