I have noticed that most people use the Pebble Seizure Detector app as a background service and rely on the audible beep warnings to prompt them to check on the person wearing the seizure detector watch.
This is fine as long as the whole system is working – watch paired with server phone and client devices connecting to server ok.
I have had some issues with the server disconnecting from the pebble watch if it goes out of bluetooth range for a while (only has to be a few minutes). The main app screen shows up warnings in bright red if you look at it, but that only works if it is on the screen.
To get around this I have just added system fault warning ‘chirps’ (very short beeps) to both the server and client apps if there is a general system fault such as not being able to communicate with the pebble, or connect to the server – these should appear as version 1.8 of the server app and version 1.3 of the client in the app store sometime today (Sunday 22 March 2015).
