Secure IoT Gateway Reference Design for BluetoothВ® Low Energy, Wi-FiВ® and Sub-1 GHz Nodes
1 января 2018
A system example demonstrating how to build a secure cloud-connected IoT gateway allowing access and control of the multiple wireless nodes. The reference design utilizes the TM4C12x, TM4C123x, TRF7970A and RF430CL330H, as well as the SimpleLink™ Wi-Fi® CC3100, Bluetooth® low energy CC2650 and Sub-1GHz CC1310 wireless microcontrollers (MCUs) development hardware and software suite for ease of development and quick time to market.
Exosite-based secure cloud connected mid-range multi-protocol IoT gateway solution using TM4C129Ex MCU, which connects Wi-Fi, Bluetooth low energy and Sub 1-GHz-based nodes to the cloud Supported nodes include Wi-Fi-based stepper motor control, Bluetooth low energy SensorTag, Bluetooth low energy slave node and Sub-1 GHz slave nodes Connection between nodes and gateway using NFC-based secure out-of-band pairing. Secure data communication between nodes and gateway using hardware crypto blocks Secure cloud connection using TI-RTOS NDK and WolfSSL stack TI-RTOS is used for task scheduling and peripheral access
