Gateway is a combination of Bluetooth + Ethernet modules, which can communicate with any

BLE compatible device and transfer the data to the server using the on board Ethernet

module.

Basically the communication between the Bluetooth module and the Ethernet module happens

via UART.

USR-TCP232-T2 is a tiny size serial TTL UART to Ethernet module which can realize data

bidirectional transparent transmission between TTL and RJ45 port. It can also be applied in

rs232/ rs485 by level shift circuit. USR-TCP232-T2 is based on Cortex-M0 core. It has

characters of low power, fast speed and high efficiency.

The BLE section contains a 32-bit ARM Cortex-M3 processor that runs at 48 MHz as the

main processor and a rich peripheral feature set that includes a unique ultralow power sensor

controller. This sensor controller is ideal for interfacing external sensors and for collecting

analog and digital data autonomously while the rest of the system is in sleep mode.

The Bluetooth Low Energy controller and the IEEE 802.15.4 MAC are embedded into ROM

and are partly running on a separate ARM Cortex-M0 processor. This architecture improves

overall system performance and power consumption and frees up flash memory for the

application.
