I am trying to pair my Sparkfun nRF52832 breakout board (programed through Arduino, using this link: nRF52832 Breakout Board Hookup Guide with a BLE android app (which I hope to make) so that I can turn on/off the LED on the board (baby steps). Since I am new to Bluetooth LE, I decided to use the BluetoothLeGatt source code on Android Studio. After going through the code, I understand how it works.

I connected my Samsung Galaxy S8+ and installed the BluetoothLeGatt source app to see if it can scan for the nRF52832. At first I got a red text in the logcat which said that I needed to give Coarse location permission, so I did that in the manifest.xml. Then I ran it again, but I still got the same red text in the logcat.

At first I googled the problem and found this somewhat similar question, however, I wasn't able to get a suitable answer. I also tried to see if I could find source code for the nRF connect app, however, that is also not available. So I'm super confused about what I should do to get rid of that and need help.

Thank you for taking the time to read my first post! I truly appreciate any help you can provide.

You need to request this permission in runtime.
