I have the basic DA14580 devkit, but I cannot get it to start advertising with any of the examples so that it can be detected in Android, whether the system Bluetooth scanner or apps like LightBlue. I have also tried scanning for it in Windows.
I can build the samples fine and load them to the board using smart snippets toolbox 'booter' utility. I know this works because I loaded the blinky app and saw that working correctly (blinking green LED), I can also debug/run the apps using Keil.
AFAIK the button on the devkit is a reset button, so I don't think I have to press that to begin advertising. I also looked at the code and it doesn't look like it's waiting for a button press from a GPIO pin or anything like that. It should just be advertising on boot.
I am wondering if I have somehow cleared some essential data off the board, data that isn't part of the built applications, but I am clutching at straws with this.
Any ideas why I cannot see my devkit in LightBlue when running apps like the proximity reporter?
