Wireless M-Bus Protocol Software



The Wireless M-Bus standard (EN13757-4:2014-2) specifies the RF communication link between water, gas, heat, and electric meters and the data collecting devices. It is widely accepted in Europe for smart metering or Advanced Metering Infrastructure (AMI) applications. Wireless M-Bus was originally targeted to operate in the 868 MHz band, which gives a good trade-off between RF range and antenna size and provides a link budget suitable for a Home Area Network range inside buildings. Two other ISM bands in Europe, 169MHz and 433MHz, were added later to the wM-Bus specification, introducing narrow-band solutions with significantly higher link budget and thus enabling longer range solutions such as Metropolitan Area Networks in dense populated cities.

Software solutions:

  • wM-Bus stack – For customers who want to shorten their development cycle and develop metering products TI provides an OMSv4.1.2 compliant and field proven wM-Bus stack. This is a full SW solution, supporting the SimpleLink Sub-1 GHz and Dual-Band wireless MCUs. The stack is provided “free-of-charge” and royalty-free when used with CC1310 and CC1350.

NOTE: Multiple other TI hardware platforms, including the two-chip solution of the MSP430 + CC112x and CC120x high performance transceivers are also supported, specifically the 868 and 169 MHz bands.

Learn more about the two-chip solution>

For more information regarding the MSP43x + CC112x/CC12x0 CIG (Italian Gas meter requirements) compliant stack solution contact your TI sales representative.

Support for the wM-Bus stack is available from Stackforce GmbH. Services include stack customization and porting to hardware platforms beyond Texas Instruments’ reference design.

  • Uni-directional S1-,.T1- and C1-mode Meter configuration at 868 MHz
  • Bi-directional S2-, T2- and C2-mode Meter configuration at 868 MHz
  • Bi-directional S2-, T2- and C2-mode Data Collector configuration at 868 MHz
  • 115.2 kbps UART interface with Serial Command Interpreter (to external Host MCU)
  • API interface for integration of the wM-Bus Stack into own application
  • OMSv4.1.2 compatibility (an OMSv4.0.2 Stack version for backwards compatibility with installed devices in the field is available as well).
  • Ultra-low power in sleep (UART interface inactive for Meter devices)

What's Included

  • Binary Meter images for TI wM-Bus stack for S1, S2 or T1_C1 and T2_C2 combined wM-Bus modes for OMSv4.1.2 for a Meter device
  • Binary Meter images for TI wM-Bus stack for S2 or T2 and C2 (C2_T2 combined) wM-Bus modes for OMSv4.1.2 for a Data Collector
  • CCS project configurations for “Serial” or Network processor function for each mode and either Meter or Data Collector
  • CCS project configurations for “Embedded” or “API” function for each S-, T and C-mode and either Meter or Data Collector
  • Extensive documentation of both Serial and API interfaces in HTML format
