HOW DO WE CONNECT REMOTE DEVICES?

“Museum of Communications” by Adam Foster https://flic.kr/p/dtwgV7

“MQTT is a machine-to-machine (M2M)/Internet of Things connectivity protocol.

It was designed as an extremely lightweight publish/subscribe messaging transport.

It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.”
