uNabto Dartino Library

This library enables the usage of the uNabto framework from within Dartino. The accompanying example app.dart controls a virtual light using the framework.

NOTE: Due to limitations of the Dartino FFI library, included in the latest Dartino SDK, this is currently only working on a local PC.

Please also refer to this article on the Nabto blog for more information.

How to set it up

Step 1: Clone the repository

git clone --recursive https://github.com/nabto/unabto-dartino
cd unabto-dartino

Step 2: Download and unzip the Dartino SDK

unzip /tmp/dartino-sdk.zip

Mac OS

curl "https://storage.googleapis.com/dartino-archive/channels/dev/release/latest/sdk/dartino-sdk-macos-x64-release.zip" -o "/tmp/dartino-sdk.zip"
unzip /tmp/dartino-sdk.zip

Step 3: Build the C library

mkdir build
cd build
cmake ..
make
cd ..

How to use the example application

Add a new device on developer.nabto.com and enter it's Device ID and Key in line 10 of the src/app.dart file.

Now you can run the example application with the dartino tool

./dartino-sdk/bin/dartino run src/app.dart

You should see a log printout similar to this:

15:18:54:118 unabto_common_main.c(127) Device id: 'devicename.demo.nab.to'
15:18:54:118 unabto_common_main.c(128) Program Release 123.456
15:18:54:118 unabto_app_adapter.c(698) Application event framework using SYNC model
15:18:54:118 unabto_context.c(55) SECURE ATTACH: 1, DATA: 1
15:18:54:118 unabto_context.c(63) NONCE_SIZE: 32, CLEAR_TEXT: 0
15:18:54:118 unabto_common_main.c(206) Nabto was successfully initialized

15:18:54:118 unabto_attach.c(787) State change from IDLE to WAIT_DNS
15:18:54:118 unabto_attach.c(788) Resolving dns: devicename.demo.nab.to

15:18:54:330 unabto_attach.c(809) State change from WAIT_DNS to WAIT_BS
15:18:54:353 unabto_attach.c(474) State change from WAIT_BS to WAIT_GSP
15:18:54:364 unabto_attach.c(266) ########    U_INVITE with LARGE nonce sent, version: - URL: -
15:18:54:375 unabto_attach.c(575) State change from WAIT_GSP to ATTACHED

We can now connect to the uNabto server by going to devicename.demo.nab.to in the browser of your choice. (devicename is the unique name created at developer.nabto.com). The browser will present us a login prompt, simply click guest. We can now control the virtual light by moving the slider.

Light 1 turned OFF!
Light 1 turned ON!

For demonstration purposes, the example application closes the server connection after ~10 seconds.
