Can't connect to Blinky application

[nemunoz]

Hi to everyone!

I have a problem when I try to connect to the Blinky application running on my nRF52dk.

My mobile phone (Nexus 5X, Android 7.1.2) is able to detect the Nordic_Blinky peripheral service on the board, but when I click to connect:

1. The board turns off the LED 1 and turns on the LED 2. My mobile phone shows a light bulb off and the word "disconnect" in the black button at the bottom.
2. In a half second, The board goes to de initial state (the led 2 turns off and the led 1 turns on) and, in my mobile phone, it changes the word "disconnect" to "connect". So, it doesn't connect.

If I press the button "connect", the same happens in the points 1 and 2. In the phone, I have tried the nRF Blinky Android app and the nRF Connect app, with the same results.

In the board, I have tried the code (compiling and updating it to the board) and the hex file (comes with the examples).

I've been able to try other code (Heart rate monitor and Proximity demo) and works perfectly with the board.

What could I be doing wrong?

I had this error once before. Here is how I fixed it.

Restart bluetooth on the phone and restart the DK. Go into the nrfConnect app and try to connect to NORDIC_BLINKY. Even if it doesn't connect, click the ... at the top right corner when you are on the NORDIC_BLINKY tab that opened up. Then click refresh device cache. Then try and connect (may take 1 or 2 tries).

Then everything started working fine for me.

Hope this helps.
