blessTags

Description

The BLE SensorTags (blessTags) application is able to communicate with: CC2451, CC2650 (both produced by Texas Instruments Company), ThunderBoard React, ThunderBoard Sense (both devices produced by Silicon Labs Company) and with other unknown types of SensorTags.

In its actual stage of development, the blessTags application:

1. allows to set, communicate, use, display (in graphic and numeric ways) and save data from all sensors included in each of the SensorTags presented above;

2. includes the GADGETS - the most exciting feature. The gadgets are several practical applications (compass, movement security systems - door or luggage security, magnetic security system, accelerometer mouse, remote control for PC and wireless presenters for PowerPoint) that use one or more sensors from a specific SensorTag to achieve a concrete, fully functional and useful application.

3. can trigger a visual or/and an audible warning or/and a data saving process will be started if an event will be generated - if the desired value (instantaneous, mean or variance), of a specific sensor, meet a condition or a series of conditions (is lower, higher, inside or outside of a specific range);

4. gives the possibility to interrogate several types of unknown BLE devices, in order to obtain the complete GATT attribute table for those particular unknown devices;

5. include the developer mode - the blessTags provides to the user lots of messages obtained from the communication process with the SensorTag - these messages enable the user to identify the communication/configuration setbacks and some other problems;

6. allows the determination of the optimal Kalman filter parameters. These parameters are extracted having as source: (A) the MPU-9250 Inertial Measurement Unit (IMU) – for CC2650 SensorTag or (B) the IMU-3000 (gyroscope sensor) and KXTJ9 (acceleration sensor) – in the case of CC2541 SensorTag.

The supported sensor’s characteristics are:

A. For CC2541: accelerometer, gyroscope, magnetometer, temperature (IR and normal), barometer, humidity, keys and output LEDs.

B. For CC2650: accelerometer (+wake-on-motion), gyroscope, magnetometer, temperature (IR and normal), barometer, humidity, luxometer, keys, reed switch and output LEDs.

C. For ThunderBoard React: accelerometer, orientation, temperature, humidity, light (ambient & UV), keys and output LEDs.

D. For ThunderBoard Sense: accelerometer, orientation, barometer, temperature, humidity, air quality (CO2 & TVOC), light (ambient & UV), sound level, keys and output LEDs (2 x low power LEDs & 4 x power LEDs).
