[YakaMein]

Hi Nordicsemi Team,

The one of our customers recently purchased NRF52-DK (Dev. Kit) which was Ver 2.1.0.

But This time has issue.

He thinks after version 3.0.0. cause the problem.


 

It seems like more switches were added and IC sized different than Version 2.1.0 2021.35 which normally working.

So, the questions are,

*He requires the information what's the differences between those models and how to make it work Version 3.0.0? 



Can you give us some advice?


Thank you so much.

Hi

He should use this Interface MCU firmware for the latest nRF52 revision: 

Please provide more context on where this "Target connection error" occurs. In Visual Studio Code or the nRF Connect Programmer app? The full log of what's occurring would be helpful to understand what exactly goes wrong.

Best regards,

Simon
