Hi Neiloca, unfortunately I don't think I can help you. I am not an active developer, merely another eCoach user. I've only applied and modified a patch by Antti so that it worked with my Polar belt and then recompiled and released .debs for 1.64 and 1.66. The latest .deb works fine on my N900 with the community SSU release. Do you have problems starting eCoach, or problems connecting to the Polar heart rate belt? --Martin
