Version 1.3 of Beacon Scanner and Logger has been released to Google Play. The new version allows the app to continue scanning when in background mode, but not while the phone is locked or has automatically entered sleep mode. I'm investigating the best way of implementing scanning while locked for a subsequent version of the app.
As usual, the app is available to download for free, and source code is available on GitHub.
Reviews and comments are welcome, and if there's a feature you'd like to see then please let me know.
