Simple implementation to connect to a MeU and display text or images

MeU Android SDK

About

version: 0.0.2

Simple implementation to connect to a MeU and send text, images or custom data over bluetooth.

What is the MeU? It's a flexible, wearable, programmable LED panel.

Repository Structure

This repository has 3 folder.

• SDK-libs This folder contains 2 jar files needed to incorporate the SDK into your project.
• MeU This folder contains the source code for the MeU SDK, and may be used a reference, or modified as desired.
• MeuSample This folder contains the sample project.

Usage

The current implementation provides for 2 jar files which should be included into the projects build path. This may be achieved by adding these files to the libs folder in an eclipse based android project.

Make sure the your project has bluetooth permissions. You can obtain these by adding the following lines to your AndroidManifest.xml, before the <application ...> tag

<uses-permission android:name="android.permission.BLUETOOTH" />

Create and initialize an instance of the SDK like so:

MeU MeU = new MeU();

and initiate the bluetooth connection using the SSID of the MeU, like so:

MeU.setupBluetooth(getApplicationContext(), "00:06:66:6A:CB:9A");

Make sure to replace the SSID above with the one for your MeU.

Now you are read to send text, using the sendText method.

MeU.sendText("This is awesome!");

MeU.sendText("I like RED!", "FF0000");

Or bitmaps using

MeU.sendImage(mBitmap);

Or if you modify the code running on the MeU you can still use this library to connect and send custom strings using

MeU.sendRaw("YOUR CUSTOM STRING HERE");

There are a few more methods available (such as listing currently available MeUs, getting the bluetooth status etc). The full source and a sample app is bundled in this repository for reference.

That's pretty much it, enjoy!

Sample

I've also include a sample app to help you along should you get stuck somewhere. Here's what it looks like:

Feedback

This was pretty much hacked together in a couple hours to make development easier for others. If there's enough interest, I'll make time to fix this up by adding proper interfaces for event handling AND a disconnect and clean up method.
