2 min | 6581This 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.

3 min | 3873After 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:
- nRF24Things - Related post: here
- SensorTag-Things - Related post: here
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.

The release notes seem promising!
I have also some new things with Docker and Raspberry Pi!
This article is outdated! I wrote the following new articles:

2 min | 2845Hi!
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!)
ViewWebis available!
This time you need to use the Android Things Console to download the image as follows:
- Go to: Android Things Console and sign in using your Google credentials
- Click on: Create a new Product
- 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
- Make a coffee or just wait a coupl...

1 min | 3782Two 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,
WebViewis still not supported on Android Things.The code can be found here:

1 min | 1078I've recently updated the
nRF24Thingsproject. I introduced some changes to the database main table (sensors) and to the handler classDatabaseHandler. Additionally, I added a second table for the payloads (payload). The two tables are related using the foreign keynodeID. I added some search options for the payloads: search by payloadID, nodeID etc.The main idea of this project is to measure the humidity, temperature, air quality etc. of a room with multiple sensors (may be using the Pi...

I've recently updated the code for the communication between the raspberry pi v3 and the rf24l01+ module using android things (0.)4.1.
You need the following things:

I've just uploaded the Java codes for the
rf24,rf24Networkandrf24Meshthat work with Android Things. This time I didn't write a library because I thought it was better to upload an Android project that can be opened with Android Studio (>2.2.3) and directly started on the Raspberry Pi. I think this can also work with NXP Pico i.MX6UL and Intel® Edison with minor modifications (especially in theBoardDefaultsfile).In thi...

2 min | 2734Hi everybody! I am back again! After almost a-two whole week(s) of code cleaning and updating I've just uploaded two 'new' libraries:
![C]()
![C++]()
RF24: https://goo.gl/3fTmlJ
RF24Network: https://goo.gl/KONmkUThese libraries are an extension to the great nrf24 libraries provided by TMRh20 and allow to connect the nRF24L01+ to the following TI-Launchpads:
- MSP430G2553
- MSP430F5529LP
- TM4C1294XL
- more are coming in the next days!
In the following days I am updating some example codes for CCS (Code Co...
