Resolving the issue of the number of BLE sensors connected and the connection distance
In recent years, BLE has been widely used as a wireless standard for environmental sensors.
In order to make this sensor using BLE IoT, we use smartphones and tablets as gateways.
However, the number of BLE sensors connected and the connection distance were issues.
Cassia Networks' BLE Router introduced this time is a solution to eliminate the above issues.
Also, by using it in combination with the TI Sensor Tag CC2650STK, an app that can already be monitored is provided.
So you can start evaluating environmental sensor monitoring today.
This article introduces Cassia Networks products and operation verification using SensorTag CC2650STK from Texas Instruments (hereafter TI).
Cassia Networks BLE Router
Cassia Networks provides a BLE Router capable of multiple connections and long-distance transmission.
The indoor E1000 can connect up to 40 terminals, and the outdoor X1000 can connect up to 22 terminals.
In listening mode, such as receiving Beacon, it is possible to receive information from hundreds of terminals.

Cassia Networks' proprietary Firmware and patented technology enable multiple connections and long-distance connections with smart antennas and noise canceling technology.
In addition, Cassia Networks provides software called Access Controller, which enables remote management of multiple routers as well as BLE terminals.
TI Sensor Tag CC2650STK
The SensorTag IoT Evaluation Kit (CC2650STK) is a product from TI that integrates light, digital microphone, magnetometer, humidity, pressure, accelerometer, gyroscope, magnetometer and ambient temperature sensors in a small package.
It can operate using a coin battery CR2032, achieves low power consumption, and can be used for applications that do not require a battery.
By connecting this TI SensorTag CC2650STK and Cassia Networks BLE Router, it is possible to acquire sensor information remotely.
The network topology for remote access is shown in the diagram on the right.
Cassia Networks BLE Router Uplink supports wired LAN, Wi-Fi, and 3G/LTE USB Dongle.
The following is a screen that connects two TI SensorTag CC2650STK and acquires data with a web application.
If you purchase Cassia Networks' BLE Router, you can connect existing BLE4.x terminals that have been used so far to multiple terminals/long distance connections.
