# cc2650-driver
cc2650-driver is a java library for using [TI SensorTag CC2650](http://processors.wiki.ti.com/index.php/CC2650_SensorTag_User's_Guide) by [bluez-dbus](https://github.com/hypfvieh/bluez-dbus) with [BlueZ](http://www.bluez.org/) version 5.50 on linux OS. I releases this in the form of the Eclipse plug-in project.
You need Java 8 or higher.
CC2650 is powered by a button battery **CR2032**. From CC2650, cc2650-driver get battery level and the following sensor information.
- System information
- Firmware version
- Battery level
The battery level is available for firmware 1.30 or higher.
- Sensors
- IR Temperature (Object / Ambience)
- Relative humidity
- Barometric pressure
- Optical
- Movement (Gyroscope / Accelerometer / Magnetometer)
There are two ways to acquire data from various sensors of CC2650.
- Direct reading
- Notification
The data acquisition interval that can be specified by notification is 2550 (msec) at maximum.
In addition, for `Movement`, when CC2650 detects a shake using Wake-On-Motion function, it may notify ` Movement` data at a time interval specified by notification for 10 seconds.
I do not know how long CC2650 battery is effective. In addition, it seems that the sensors of `Movement` has relatively large power consumption. When the battery level reached approximately 60%, empirically CC2650 could not work properly.
I have confirmed that it works in Raspberry Pi 3B ([Raspbian Buster Lite OS](https://www.raspberrypi.org/downloads/raspbian/) (2019-07-10)).
## Install Raspbian Buster Lite OS (2019-07-10)
The reason for using this version is that it is the latest as of July 2019 and [BlueZ](http://www.bluez.org/) 5.50 is included from the beginning.
## Install jdk8 on Raspberry Pi 3B
For example, the installation of OpenJDK 8 is shown below.
```
# apt-get update
# apt-get install openjdk-8-jdk
```
## Install git
If git is not included, please install it.
```
# apt-get install git
```
## Use this with the following bundles
- [SLF4J 1.7.26](https://www.slf4j.org/)
- [Apache Commons Lang 3.9](https://commons.apache.org/proper/commons-lang/)
- [dbus-java-osgi 3.2.1-SNAPSHOT](https://github.com/hypfvieh/dbus-java)
- [bluez-dbus-osgi 0.1.2-SNAPSHOT](https://github.com/s5uishida/bluez-dbus-osgi)
I would like to thank the authors of these very useful codes, and all the contributors.
