Wireless M-Bus Stack

The famous wireless M-Bus protocol stack by STACKFORCE leads to competitive products that are easy to install and maintain. The stack implements all protocol elements that are required for wireless M-Bus compliance and provides additional tool support. It is optimized towards a compromise of small footprint, excellent modularity and scalability, but though being feature-rich.

STACKFORCE has partnered with multiple industry leading silicon vendors, thus the stack has already been ported to various platforms.

Variants of the wireless M-Bus Stack

Our Wireless M-Bus Stack is not just available as a standard version, compliant to EN 13757 and OMS specification, but also as derivatives in conjunction with MIOTY^® or LoRaWAN^®. Therefore you do not only benefit from the well-proven, well-spread and popular Wireless M-Bus protocol, but also from the advantages of new LPWAN (Low-Power Wide Area Network) technologies. The'yre enabling larger transmission ranges, which especially of interest for applications like Metering and Smart City.

Wireless M-bus mode and device type selection

Selection of mode (S, T, C, N), direction (unidirectional / bidirectional) is possible

during compile time to shrink the memory footprint.
during runtime to permit flexibility at any time in the field.

Flexible Software Timer

Dynamic hardware timer adaptation including compensation in order to occupy only one hardware timer (and an RTC if applicable) for all wireless M-Bus related timings.

Support of any type of non-volatile memory

EEPROM, Flash, MRAM, …
internal / external (e.g. connected via SPI)

Commercial features

first level support
easy commissioning and configuration
warranty and maintenance
ensures a high quality product
