Hi Dialog, my name is Kevin.
So far as I am working, I was able to connect DA 14580 ( using my custom board ) to Smart Snippets,
I have succeeded to burn blinky and other peripheral code, and it's working.
The problem is when I tried to burn ble_app_peripheral , the following message which I attached in this post is appeared
For Antenna Design, I use antenna design referring to page 24 of document an-b-027.
What is causing the problem, and what is the possible mistake from our side?
Is it caused by antenna design, or what kind of fault ?
