Low-Power Wireless M-Bus Communications Module Reference Design


Design files


This reference design explains how to use the TI wireless M-Bus stack for CC1310 and CC1350 wireless MCUs and integrate it into a smart meter or data-collector product. This software stack is compatible with the Open Metering System (OMS) v3.0.1 specification. EN13757-1 through EN13757-7 are European standards for meter reading and include both wired and wireless metering-bus (M-Bus); these together are very popular in ultra-low-power metering and sub-metering applications. This design offers ready-to-use binary images for any of the wireless M-Bus S-, T-, or C-modes at 868 MHz with unidirectional (meter) or bidirectional configurations (both meter and data collector). Multiple precompiled binary images are provided that cover metering applications, including but not limited to heat cost allocators (HCAs), gas, water, and heat meters, or e-meters with an external host MCU.

  • Meets EN13757-4 class HR requirements for sensitivity and selectivity and class HT for transmit power in S-, T-, and C-modes
  • Complete single-chip implementation with serial interface to host MCU
  • Consumes only 0.7 µA @ 3.6 V in shutdown mode
  • Embedded (API level) interface for combining wM-Bus stack and meter application
  • wM-Bus OMSv3.0.1-compliant S- and T- modes (S1, S2, T1, T2) with C1 and C2 modes added
  • Supports meter and data collector (also called "Other") functionality
