Thanks for sharing your findings.

My issue was little different but I thought better to share it on the forum.

In nrf_connect ( in an android phone ) 'NORDIC_BLINKY' was not visible at all.

Solution: Got to setting -> Apps-> Nrf_connect-> storage -> clean data

And now start nrf_connect again and everythings works fine.

I think the issue was caching only.

Hope it helps someone in the future 🙂

Thank you. That's not the solution but you help me to find it.

The problem was I have cached the other BLE examples, so the discovering bluetooth process wasn't completely done.

After trying to connect in nRF Connect app, I checked the log (I didn't know it has it) and I find the next line error:

Error 22 (0x16): GATT CONN TERMINATE LOCAL HOST

I googled it and ended here, where it solution gave me the idea to my solution.

Here are the steps I follow to make it works:

In nRF Connect, scan and find Nordic_Blinky, press the three points (...) and select something like "remove bonded data" (now that option doesn't appears, I don't know why).
Connect to Nordic_Blinky (now you see It doesn't disconnect) and disconnect to use the Blinky app.
Here you are! Now you can use nRF Blinky app without problem.

I Hope someone find this useful to solve the same problem (or others, who knows).

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.
