Texas Instruments Sensortag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application, which I recently tried in Linux. Until now, only it was only officially supported in iOS and Windows, but a few days after the release of Android 4.3 which adds Bluetooth Low Energy support, Texas Instruments quickly worked to release an Android App for their BLE devkit. The annoying part is that the Android app is only available as a Windows executable (SensorTagAndroidApp-0_9_0-windows-installer_2.exe), so you’ll have not choice but to use Windows to uncompress the files. Yet the installation goes as follows: Copy the SensorTag.apk file (SensorTag_0_9_0.apk) to your Android 4.3 device Enable installation of apps from unknown sources (Settings -> Security -> Device Administration -> Unknown Sources) Open file manager and launch, locate the .apk file and install the app by clicking the […]

Using ARM Development Studio 5 (DS-5) Streamline with MK802II mini PC

MK802-II is an Android 4.0 mini PC powered by AllWinner A10 (ARM Cortex A8) with 1GB RAM and 4GB flash. Instructions are also available to run Ubuntu, or other Linux distributions. ARM Development Studio 5 (ARM DS-5) is software development tool suite for ARM processors that can be used for both Linux and Android debugging, and available in 2 versions: professional edition and community edition, the latter being free of charge. I’m writing about both today, because Bob Peng, Technical Marking Engineer for ARM China, recently wrote a blog post in Chinese [Update: An English version is now available] showing how to use MK802-II, preloaded with the required drivers and daemon, with DS-5 Streamline Performance Analyzer with is part of both versions. The community edition may be missing some features of Streamline however. Streamline Performance Analyzer allows you to: Find out which modules or functions to take up most of […]
