Wireless M-Bus

EN 13757 and its substandards The Wireless M-Bus standard is more or less a marketing name for the european standard for wireless meter readout (EN 13757-4), which lies underneath the generic european standard for remote readout of meters (EN 13757-3).

However, those EN 13757 standards do not specify a full featured protocol, as there are several gaps within the specification which cause different interpretations, and the standards also specifies features and formats, that most likely won't be used by anyone.

Therefore, we would describe the Wireless M-Bus is like specifying a pool of features and formats, as a base for other standards, what we call sub-standards (e.g. OMS, DSMR, GrDF, CIG/UNI-TS, ...). This picture using the sub-standards OMS and DSMR as an example, describes the situation the best:

Texas Instruments

For the TI product families, STACKFORCE offers a broad support. This includes derivatives of the MSP430 microcontrollers (like MSP430FG4618, MSP430G2955, MSP430F5438A, ...), and RF transceivers like CC1200 and CC1120/1125. In addition, for specific application also the single-chip system CC430 is supported.

This application demonstrates the usage of the Wireless M-Bus Stack using the Texas Instruments' eZ430-Chronos Wireless Watch Development Tool as data collector and the MSP430FG4618/F2013 Experimenter Board as meter device.
