Laird Connectivity has announced the Sentrius MG100 Micro-Gateway to simplify the bridging of Bluetooth sensor data to the cloud.
Powered by the Pinnacle 100 cellular modem, the product combines long-range Bluetooth 5 (Nordic nRF52840 silicon) and LTE-M and NB-IoT (Sierra HL7800 and Altair ALT1250) in a small form factor IoT micro-gateway. This wireless combination enables new use cases for long-range Bluetooth sensors to bridge sensor data to the gateway, then up to the cloud, all in a simple and low-cost architecture.
The gateway leverages the power and simplicity of Zephyr RTOS programming on the integrated Arm Cortex-M4F microcontroller, allowing developers to tailor their application to their requirements. Flexible product options are also available including a rechargeable backup battery in the event of a short-term power outage.
"Because the Sentrius MG100 Micro-Gateway is based on the Pinnacle 100 modem, it's easier than ever to bridge wireless sensor data to the cloud over an LTE-M or NB-IoT connection," said Bill Steinike, vice president of Ohio-based Laird Connectivity. "This gateway brings market-leading wireless technology and software that speeds time to market by eliminating the complexity, design risk and certification costs that cellular IoT typically has."
To suit their application environments, users have the option of using fully integrated antennas or external antennas. The gateway is cloud ready, compatible with cloud services such as AWS. Customisation is also available including custom branding, packaging and application development.
For more flexibility, Laird has paired the MG100 with the Sentrius BT510 Bluetooth 5 long-range multi-sensor. The gateway and BT510 starter kit provides a quick and simple way to start evaluating wireless IoT systems. This kit includes one gateway with an installed SIM card, three sensors and global power supplies, everything needed to test and validate applications from a single box.
"Our goal is to make developing wireless IoT systems easier for our customers," said Steinike. "With these new LTE starter kits, our customers get closer to production-ready in minutes right out-of-the-box and our engineering and customisation services help them get up and running in the field as quickly as possible."
The gateway is suitable for multi-wireless IoT applications where long-range Bluetooth sensors bridge directly to the cellular network without the need to access any local network infrastructure. It works in any location with appropriate cellular coverage. Applications include security and building automation, industrial IoT, medical IoT, consumer IoT and smart buildings.
The gateway will be fully end-device certified from a radio regulatory and LTE carrier perspective, eliminating those costs for user applications. Certifications will include FCC, IC, CE, BT Sig, PTCRB and GCF, and it will be end-device certified with AT&T, Verizon and Vodafone.
