Not sure what the GP is using, but on Android the Nordic BLE app is very good - https://play.google.com/store/apps/details?id=no.nordicsemi....

I'm also one of the authors of RaMBLE, another BLE app (https://play.google.com/store/apps/details?id=com.contextis....). It can run in the background, and can export logged BLE advertising packets and geolocation data to a SQLite DB.

I installed Ramble half an hour ago on my 2014 Moto G and it seems to be working as advertized! The only thing which confuses me is the empty list under the history tab. Is this a bug or is this feature not implemented yet?

The history tab is pull-to-refresh, but it's not particularly discoverable :)

I've implemented a UI hint to make this more obvious, which will be in the next version of RaMBLE.

You are right, pull-to-refresh was not very discoverable ;) Somehow I an auto-update function for a tab called "history".

Another thing I just realised is the number of new devices in the notification label. Let's say I put ramble in the background. After 10 minutes it tells me that there are n_1 new devices. I click on the notification in order to check them out. If I then put ramble in the background and it finds n_2 new devices then the notification says that there are now n_1 + n_2 new devices. I would expect that it says n_2 devices.

The notification is a summary of the current scan (until you stop it). New devices are ones you've never seen before the current scan. I often run it on my commute, the 'total' number give me an idea of how busy (in terms of BLE devices) it is today.

If you export the database you can pull some more interesting numbers out, e.g. http://www.contextis.com/resources/blog/bluetooth-le-increas...
