Low-Power Wireless M-Bus Communications Module Reference Design
Description
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.
Features
- Meets EN13757-4 class HR requirements for sensitivity and selectivity and class HT for transmit power in S-: T-: and C-modesComplete single-chip implementation with serial interface to host MCUConsumes only 0.7 µA @ 3.6 V in shutdown modeEmbedded (API level) interface for combining wM-Bus stack and meter applicationwM-Bus OMSv3.0.1-compliant S- and T- modes (S1: S2: T1: T2) with C1 and C2 modes addedSupports meter and data collector (also called Other") functionality"
