Sentrius MG100 Gateways Ezurio Sentrius MG100 Gateways are powered by Ezurio's Pinnacle™ 100 Modem. The Ezurio Sentrius MG100 Gateway captures data from BLUETOOTH® 5 long-range sensors and sends it to the cloud via a global low-power cellular (LTE-M/NB-IoT) connection. This open-development device for custom application development leverages the power and simplicity of Zephyr RTOS programming on the integrated Cortex-M4F microcontroller to tailor applications.
