Wireless M-Bus Protocol Software



The Wireless M-Bus standard (EN13757-4:2005 and 2012) specifies the RF communication link between water, gas, heat, and electric meters and the data collecting devices. It is becoming widely accepted in Europe for smart metering or Advanced Metering Infrastructure (AMI) applications. Wireless M-Bus was originally targeted to operate only in the 868 MHz band, which gives a good trade-off between RF range and antenna size. Two new bands (169MHz and 433MHz) were added to the wM-Bus specification as well, introducing narrow-band solutions with much higher link budget and thus providing longer range solutions than at 868MHz.

What does TI provide to help designers?

Hardware platforms:

Software solutions:

  • wM-Bus stack – For customers who want to shorten their development cycle and develop metering products TI provides an OMSv3.0.1 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 two-chip OMSv3.0.1 and 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.
