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.
