I'm working on an ESL project using the nRF5340-DK. I need to enable the PAwR feature, which requires Bluetooth 5.4. However, my current program is written using nRF Connect SDK version 2.6.1, which only supports Bluetooth 5.1. I want to upgrade the project to support Bluetooth 5.4 and use the latest compatible nRF Connect SDK version that fully supports ESL and works properly with the nRF5340-DK.
I tried building the updated project in Visual Studio Code through nRF Connect, but it's throwing many errors and fails to build. What is the best and most appropriate way to upgrade the SDK and project to support BLE 5.4 and ensure compatibility with the nRF5340-DK?
