Renesas Electronics and Steinbeis Transfer Centre Embedded Design and Networking announced the availability of a complete Wireless M-Bus 169 MHz/868 MHz solution to address the requirements of sub-metering applications.
The Wireless M-Bus stack conforms to the specification EN 13757 and supports all specified modes (C, N, S1, S1-m, S2, T1 and T2), as well as being extensively tested for interoperability with other solutions. On the application layer, it also supports Open Metering Specifications (OMS) v3 or Dutch Smart Meter Requirements (DSMR). OMS conformability is verified with the brand new OMS certification tool.
The Wireless M-Bus stack offered by Renesas is available on its RX and RL78 microcontroller (MCU) families, together with a choice of radio ICs. The solution includes not only the complete software stack, but also tools such as a Wireless M-Bus sniffer and PC-based web surfer from Steinbeis for rapid evaluation and testing.
Renesas is able to sub-license the Steinbeis WMBus stack as a library, together with low-level drivers for the transceivers optimised both for RX and RL78 MCU families.
