Android-nRF-Blinky not scanning

[Dlo123]

Downloaded https://github.com/NordicSemiconductor/Android-nRF-Blinky today and imported using Android Studio 3.6.3 targeting SDK 29. Gradle updated to use 3.4.2. no changes to core code, just trying to import, build and run on Android OnePlus 6t phone.

Everything compiles and builds without errors and loads to phone properly. App starts and asks for permission and it is granted. Scanning does not result in any hits.

Uninstalled app and downloaded nRF-Blinky from google play store with same results. No hit on any BLE devices around. Uninstalled and open nRF Connect, scan and properly see all BLE devices around.

Blinky app running on PCA10040 dev kit.

All other scanning apps sees it.

Learning Android apps and wanted to see a barebone example to scan and show devices, but struggling to get anything going. Help!

You may try to deny and grant again the location permission in Settings->Applications->nRF Blinky->Permissions. Also, there's a filter in the main screen (in top-right corner, an icon with 3 lines), try disabling all checkboxes and see if you can spot anything.

Still no luck. I am using the nRF Blinky from the Play store to do all these testing:

_ Check/Uncheck filter boxes

_ grant permissions via settings.

Can you download the nRF App and test it on your device? I'll try testing the app on a tablet next.

I tested the app store nRF Blinky on 3 devices:

1) OnePlus 6T running Android 10

2) Samsung Galaxy Tab A running Android 9

3) Xiao Mii running Android 9

The only one where the app worked, was the Xiao Mii android 9 phone.

I'm working on updating nRF Blinky right now. Except for this bug fixed, it will also get Dark Theme and some other improvements under the hood.
