The soft provide by Acconeer compiles and works well in Vscode but i want to add the uart peripheral in order to stream data fromen-USTelligent Community 13Thu, 04 Nov 2021 13:38:14 GMThttps://devzone.nordicsemi.com/thread/337500?ContentTypeID=1Thu, 04 Nov 2021 13:38:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6fef9a6a-9abc-440a-9a4b-3e157096e4dfJared<p>Hi,</p> <p>Seems that the issue is board dependent.
