B1: autoreset after a few minutes, how to debug

Hi,

I wrote an app which communicates with an Android app and transfers data continuously. Everything works fine until the watch seems to (soft) reset for seamingly no reason. What I did so far:

• use 2v16 release build
  
• Android app drives communication (no Bluetooth.write unless requested)
  
• continuously log memory consumption using Terminal.println and buzz when exceeding ~2/3
  
• disabled home button (set option btnLoadTimeout to 0) and implemented a 3s count down with buzz when holding a button to reenable the home button
  
  

Because it takes a couple of minutes to appear and the timespan varies a lot (observed 7m and 12m from sent data), I didn't "see" what happens on screen so far.

I would appreciate any information on what I should "log", on JS or C level, to get a grip on this.

Thanks in advance!
