With this App and a serial-bluetooth-Adapter it is possible to transmit telemetry information from a Multiplex M-Link HF module to an Android smartphone. More infos (currently only in german) on my homepage.
Discussion about the project (sorry, german language only):
The current version is a very early draft and not intended for "productive" use. I am working on a version that supports variometer and is fully configurable. The new version should be released in april 2013. This version than supports english and german as its user interface.
