Theengs Bridge BLE to MQTT gateway supports Home Assistant, OpenHAB, Jeedom, NodeRed, and more

The Theengs Bridge is a new WiFi & Ethernet BLE to MQTT gateway running the open-source OpenMQTTGateway firmware, compatible with a range of sensors, and supporting Home Assistant, OpenHAB, Jeedom, NodeRed, and other MQTT-compatible systems. It follows the Theengs Plug smart socket introduced at the beginning of the board with many of the same features (minus the socket part…) but adds Ethernet and an external antenna for improved range, and improves modularity with a Grove I2C connector and mounting holes for a LoRa-E5-based Grove module and a prototyping area where you can solder your own circuitry with DIP components. Theengs Bridge specifications: Wireless module MCU – ESP32 microcontroller with WiFi and Bluetooth Storage – 8MB flash PCB antenna and u.FL antenna connector Connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth LE with 6dBi 50Ohm external antenna Optional LoRa module via Grove I2C connector MQTT protocol Expansion – […]

MediaTek unveils 5G RedCap solutions: M60 5G modem and T300 Arm Cortex-A35 SoC

MediaTek has introduced its first 5G RedCap solutions with the M60 5G modem and the MediaTek T300 Arm Cortex-A35 SoC design to bring 5G-NR to wearables, light-weight AR devices, IoT modules, and consumer and industrial Edge AI devices. 5G RedCap (Reduced Capability), part of 3GPP Release 17, aims to keep some 5G features such as low latency, low power consumption, enhanced security, and network slicing while limiting the bandwidth (to around 85 Mbps) in order to be used in IoT devices and products that may not need the bandwidth required by smartphones and computers, but would benefit from longer battery life and a smaller footprint. MediaTek claims to be the first company to unveil 5G RedCap chips with the M60 modem and T300 SoC. MediaTek M60 key features and specifications: 3GPP Release 17 standard 5G modem R17 UE power saving R17 Coverage enhancement R17 Small data transmission LTE & NR-FR1 […]
