Meter-bus and mikroBUS™ join forces to bring you M-BUS RF click. Software library also provided.
Humanity is trying to build the Internet of Things in order to reach consumer heaven, but we are running into the same problem as the people who tried to build the Tower of Babel – there are so many different wireless standards and protocols that don’t understand each other that it’s difficult to build a single grand unified network of things.
But these protocols don’t spawn spontaneously. Each one is a reaction to a particular market demand. Just as Eskimos have 10 words for snow and Serbians have 100 words for specific cousins, each wireless protocol has features to address specific challenges.
The original wired Meter-Bus was designed for remotely reading utility meters. The Wireless M-BUS is laying the groundwork for a new Advanced Metering Infrastructure (AMI).
M-BUS operates on unlicensed frequency bands that enable long range wireless communications. Radio waves at this frequency are able to reach meters in remote locations such as behind building walls or under the ground.
Specifically, the Telit ME 70-169 module on M-BUS click operates at a frequency between 169.400 and 169.475 MHz. It has a declared range of up to 20 km. You can find more details on the product page.
Wireless modules tend to be complex on their own. To simplify development and deployment we developed a library. You can download it from Libstock. To fully appreciate it, read the article on learn.mikroe.com that explains how it works and helps you understand and utilize the multitude operating modes of the Me 70-169 module.
