STMicro STM32WL Wireless MCU Gets Wireless M-Bus Stack for Smart Meters

STM32WL Wireless M-Bus Stack

STMicro STM32WL was introduced as the world’s first LoRa SoC last year as it combined an STM32L4 Arm Cortex-M4 microcontroller with Semtech SX126x LoRa radio. The company has now partnered with Stackforce to develop a wireless M-Bus (wM-Bus) software stack that leverages the integrated sub-GHz radio and multiple modulation schemes supported by STM32WL microcontrollers. Wireless M-Bus (Wireless Meter Bus) is a wireless protocol specifically designed for remote reading of smart meters, generally gas, water, or electricity meters. The wM-Bus stack developed by Stackforce is said to comply with most of EN 13757-3/-7 specifications from lower to upper layers. The stack notably supports Wireless M-BUS modes S, T and C used throughout Europe in the 868MHz band, as well as the mode N for operation at 169MHz that also happens to be Wize frequency. Stackforce Wireless M-Bus stack for STM32WL also meets requirements for several other metering standards, including the Open […]

n-Fuse SX1302 Mini PCIe LoRaWAN Concentrator Card to Sell for 100 Euros

SX1302 Mini PCIe LoRaWAN Concentrator Card

Semtech SX1302 LoRa transceiver was announced in Q3 2019 as an updated to the company’s SX1301 LoRaWAN gateway chip with improved efficiency, lower BoM costs, and the ability to handle more traffic. At the time, the company also showcased a mini PCIe LoRaWAN concentrator card reference design pairing SX1302 with SX1250 sub-GHz RF front end, and that could be connected to a Raspberry Pi board via an interface board. n-Fuse has now come up with a commercial product adapted from the reference design with LRWCC2-MPCIE SX1302 Mini PCIe concentrator card designed for LoRaWAN gateways. n-Fuse LRWCC2-MPCIE key features and specifications: MCU – STMicro STM32 (no details provided) LoRa Connectivity Semtech SX1302 digital baseband processor with 2xSX1250 and 1xSX1261 Tx/Rx front-ends Frequency Range – 863 to 870 MHz or 915 to 928 MHz Sensitivity <= -124dBm at SF7, BW 125KHz <= -138dBm at SF12, BW 125kHz <= -125dBm at SF7, BW […]

Meshtastic Mesh Networking Project Combines ESP32, LoRa and GPS Radio

ESP32 GPS LoRa

Meshtastic is a project using off-the-shelf, inexpensive ESP32-based hardware with GPS & LoRa connectivity to create mesh networks helping hikers. skiers, paragliders, or people exercising other outdoor activities communicate short messages such as their GPS location. This allows each member of a private mesh network to see the location and distance of all other members and read/or any text messages sent to a group chat. No phone is required unless you have an ESP32 LoRa board without GPS in which case it would get the GPS coordinates from your phone over Bluetooth. A phone is also needed to send a message. The project currently works on three different boards TTGO T-Beam, TTGO LORA32 and Heltec LoRa 32. The T-Beam is recommended as it sells for around $26 plus shipping and features a 18650 battery holder so you can source the battery easily locally. Just make sure to purchase the right […]

The Things Industries Launches Global Join Server for Secure LoRaWAN

Global Join Server

Co-Founder and CEO of The Things Industries Wienke Giezeman announced the launch of Global Join Server (GJS) which is a secure component of the LoRaWan server. As an ecosystem, Global Join Server allows activating devices of any LoRa network from anywhere on the World. According to Giezeman, it works with the Things Network, the Community Network, cloud hosting solutions, etc. It works no matter if it is a part of a network server outside the Things Industries, as long it uses LoRa standard interfaces. The Global Join Server’s role is to store root keys, generate session keys and send them securely to the Network Server and Application Server. There is no more need to send keys by email or to print them on the boxes, they are already in a secure place. The Things Industries offers to device makers, module makers and distributors, access to a network-agnostic Join Server of […]

$99 RAK7246 LoRaWAN Developer Gateway Features Raspberry Pi Zero W SBC

Raspberry Pi Zero LoRaWAN Gateway

Outdoor LoRaWAN gateways meant to be deployed in the field usually cost several hundred dollars, so companies also offer cheaper gateways for indoor use that can be used by developers.
