Generating heat map using iBeacons with android application Intro About a month ago I had an opportunity to play with an iBeacon on the Android platform. My first task was to implement a proximity trigger to Android client for one of our apps at work. As we played with it, we wanted a more precise data such as a heat map. Searching I googled some familiar projects around, bud didn't find a precise app in the Play Store that generates a heat map from actual distances from iBeacons. After visualization the raw accuracies in a graph (picture below) I found this interesting page that nevertheless confirm my results. These are my observations. raw data is not as accurate as I first thought accuracy depends on rotation of iBeacon to the smart phone at some distance, the error is rising rapidly to get more precise data, you have to set a transmit interval and transmit power to the maximum, but that also leads to more battery consumption What I did I created an Android
