TI launches wireless metering bus M-BUS reference design

This reference design describes how to use TI's wireless M-Bus stack with the CC1310 and CC1350 wireless MCUs and integrate them into smart meter or data collector products. The software stack is compatible with the Open Metering System (OMS) v3.0.1 specification. EN13757-1 to EN13757-7 are European meter reading standards, including wired and wireless metering buses (M-Bus); these are very popular in ultra-low power metering and sub-metering applications. The design provides ready-to-use binary images for any wireless M-Bus S, T or C mode at 868 MHz, with unidirectional (instrumentation) or bidirectional configuration (instrumentation and datalogger). Multiple precompiled binary images are provided covering metering applications including but not limited to heat cost allocators (HCA), gas, water and heat meters, or electronic meters with external host MCUs.

An open source project for underwater sensor nodes based on single-pair Ethernet technology SPE (from tutorial to actual combat, English)

Single-Pair-Ethernet technology (SPE, Single-Pair-Ethernet) describes the transmission of Ethernet through only a pair of copper cores. In addition to transmitting data through Ethernet, it can also simultaneously provide power to terminal devices through PoDL (power supply over data lines).
