Yes; the SoftDevice is, effectively, the Bluetooth stack - so, without that, you will not have any Bluetooth functionality at all. I haven't tried working through the nRF52 docs to see how "obvious" that is, though...

I figured it out! Turns out that I needed to flash the softdevice hex file with nRFGo Studio before I could connect to the dev board.

The online getting started documentation shows installing the softdevice in the flowchart, but does not say or explain anywhere else how to do this. Also, the example BLE programs should state that the softdevice needs to be flashed before loading the application.

I have location service and GPS turned on. When I go into the nRF Control Panel permissions, the only option is Storage. I am unable to find the nRF52 dev board on the Nexus 6P, HTC One M8, and a Windows Laptop.

@nrfdev: My GPS was on already. Checked the nRF Control Panel permissions and the only one to enable is storage. I also tried to connect using an HTC One M8 and a Windows Laptop. No Luck.

So I guess that explains the GPS thing?

Also, if you don't want to give other apps an option to see your location you can deny them the location permission in the Android settings: Settings->apps->Setting icon at the top->App permissions

Hi,

On Android Marshmallow you have to enable Location service in order to scan for BLE devices. Just open the notifications and clock on the Location. The new version of nRF MCP will also ask you for the location permission when first launched. As the current version 3.4.1 targets the Lollipop API it got that permission automatically on installation.

Google guys decided that scanning for Bluetooth Smart devices could give the app information about the user's location. For example beacons may be used for indoor navigation etc. Therefore since Android 6.0 you have to have the Location permission granted and the location service enabled. It may be set to any value other than OFF.

Best Regards, Aleksander

@Blue_Alien: Can you see it from any other devices? Do you have a dongle to use the Windows version of MCP?

@nrfdev: Intriguing! Why would GPS be required?!
