      This article extends the node tree of ProjectDiva to include an Arduino Pro Mini.

      This article explains how to connect a Arduino Pro Mini to the nRF24Things application (Android Things). The code allows sending and receiving messages between the nodes. It uses the well-known nRF24 libraries to create a sensor mesh, where the node 0 (in this case a Raspberry Pi running the Android Things application) actuates as a "DHCP" server and assigns the node addresses in the mesh.

      Thanks Sal for your comments on the article TI: Sensortag CC2650 . This is for you and those who are playing with TI SensorTag!

      I've updated the repository of the Texas Instrument (TI) SensorTag CC2650. The repository can be found here . As you may know TI doesn't update the repository anymore. The original last open source repository of the application can be found here .

      I've wrote an article last year as I migrated and updated the repository:

      Today, I've updated the repository to support Android 8.1 (>6.0). The main modification was that Android >6.0 needs locatio...

      After the Hannover Fair 2018, I have this weekend some time and I decided to update the #ProjectDIVA to the last version of Android Things. Today the actual version is 0.8.1 DP and the Android Things Setup Utility has the version number 1.0.19.

      I have two applications running on Android Things:

      In Oct. 2017, I wrote a tutorial for Android Things, but I checked that the tutorial needed an update, and the repositories too. That's why I'm writing this post.

      #ProjectDIVA: nRF24Things working on Android Things DP5.1

      Android Things | 1 min | 98


      I've updated the code of the nRF24Things application. The application is now working on Android Things DP5.1. There is a Bug on DP5.1 related to the SPI units. You can read more on my last post here.

      I've tried to update the SensorTag-Things application but I didn't work. DP5.1 has still problems with Bluetooth. Due to the crash by debugging, I found and reported another bug to Google. Read here.

      As the title says, this is a getting started with Android Things. It should be my first post, but, it's better now than never. I'm posting this to summarize the steps to install Android Things on your Raspberry Pi.

      Google announced Android Things on December of 2016. It's a modified version of the Android that we all know, but for Internet of Things (IoT) devices. The architecture of the SDK is described in the following figure:

      Hi!

      Android Things DP5.1 is out! and the bugs were fixed!!! You can check the release notes here!.

      You don't need to change the config.txt for the display settings and the debugger issues were solved and it is working again (tested! - it stops at the breakpoints)!

      You can download the zipped image using the Android Things Console! Check this post for more information!

      There are some problems with my two Android Things repositories and the applications are not working as expected :( but I will be updating the GitHub repositories this weekend!

      Stay tuned! and have a nice friday!

      Hi!

      Android Things DP5 is out and of course, new features are available.

      The most important features are:

      • Runtime Pin Configuration
      • OpenGL 2.0 Support (that means hardware acceleration on the RPI!)
      • ViewWeb is available!

      This time you need to use the Android Things Console to download the image as follows:

      1. Go to: Android Things Console and sign in using your Google credentials
      2. Click on: Create a new Product
      3. Go to: Factory Image
        • Select: Empty Bundle (if you don't have any app) and the Android Things v. OIR1.170720.015
        • Click on: Create Build Configuration
      4. Make a coffee or just wait a coupl...

      Hi again!

      Two posts in one day! Now the SensorTag CC2650 is running on Android Things. The Raspberry Pi 3 can be used as a sensor hub, and the SensorTag can be connected to it using BLE. I modified the original app and now it is working on Android Things! Minimal changes were required, especially on the files related with the user interface. Moreover, WebView is still not supported on Android Things.

      The code can be found here:
