Integrated TCP/IP The device is suitable for various smart home, AT commands smart city and industrial applications. TLS/SSL for end-to-end security The system uses an STM32F103 microcontroller Over-the-air firmware updates as a bridge between the various communications SP1ML-868 module for Sub-GHz RF modules. The Wi-Fi, Bluetooth and Sub-GHz communication: certified modules are connected through a UART 868 MHz ETSI-certified module interface to the STM32 microcontroller. The NFC Based on Sub-GHz SPIRIT1 transceiver module is connected through an SPI transceiver, STM32L1 ULP MCU and interface. balun (BALF-SPI-01D3) Chip antenna Simple AT commands December 2015 DocID028388 Rev 2 1/7 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams STEVAL-IDI004V2 Detailed description The evaluation kit supports the following communication protocols: 1. Wi-Fi communication 2.4 GHz IEEE 802.11 b/g/n using the SPWF01SA 2. Sub GHz communication 868 MHz low power RF using the SP1ML-868 3. Bluetooth communication 2.4 GHz, v3.0 compliant using the SPBT2632C2A 4. NFC communication 13.56 MHz using the CR95HF The board can be connected to the PC through a USB VCOM interface. The Wi-Fi configuration parameters and the mesh node configuration can be programmed through the available PC GUI (by request). Debug log messages can also be collected through the GUI. The sensor data from any node in the mesh network (6LowPAN Contiki 3.0) is accessible through an Android application over a Bluetooth interface. The board is powered by a 5 V, 1 A wall adapter. The status of the various communication interfaces is indicated using five LEDs mounted on the board. Figure 1: Wireless Bridge WiFi/NFC/BT/RFSubGHz scenario 2/7 DocID028388 Rev 2
