Acticheck has developed Apps for iOS and Android to enable the Acticheck wristband to connect to a smartphone using Bluetooth BLE. The iOS App works reliably however the Android App which used to work reliably does not work with most newer phones.
The problem with Android seems to be related to power saving. On some phones the App works fine but then gets shut down after a few minutes or hours.
We are seeking someone who can develop a test App to prove that it is possible to implement an Android App that can always be listening for BLE advertisements and connect to the wristband. Acticheck will then use this as the basis for a new version of the App.
The current App is written in Java using Android Studio.
