Thingy Disconnects from GitHub Android App

[cprehn]

Details

Hardware: Thingy52, nRF52840 Dev Board, Samsung Tab A running Android 5.1.1

Software: Windows 10, using GCC for compilation, Thingy52 SDK, Android-Nordic-Thingy-master from GitHub

I'm trying to run the Android app from the GitHub to connect with a Thingy, but when the two try to connect, the Thingy says it connects.  Immediately, though, it disconnects.  Segger RTT reveals this:

The Thingy can connect to the app store versions of the Thingy app, but when I try loading the GitHub version and running it, the Thingy refuses to connect.  Eventually, I'd like to modify the Android app, but I need to be able to connect and send the default data first.

I've found someone else having the same issue.  The project is time sensitive so I decided to take it to a private forum.

What could the issue be?

Thanks!

I flashed a Thingy with the default hex of the firmware to narrow down what the cause of the issue could be, but the app would still disconnect from the Thingy.  I also tried compiling the GitHub versions of the firmware and Android code, but that still produce the same issue.

I have been able to test the Android store app on another Android device, which was successful with both the custom and default firmware, but I haven't been able to try the custom Android app on a device other than the tablet.  However, I do suspect that it's the tablet causing the issues and not the app or firmware at this point.  I'm going to try getting a hold of another Android device to test on.  I'll also grab some sniffer trace data with the tablet.

 

Thanks!
