As part of the preparation for getting the Android application ready for Android Market, we released a simple tool called Bluetooth Viewer (a few weeks ago). This tool was in fact our first Android application we used for debugging and testing Bluetooth sensor devices. We released it a few weeks ago, and just like the upcoming EcoCitizen Android application, it is open source. Read more about it here.
EcoCitizen Android updates: in December we will release the last milestone before the official Android Market release, which is expected in January.
EcoCitizen Map updates: in December we will release some major changes, but much work will remain still, so there will be several more milestone releases.
