How to hide beamer subsections from the table of contents for non highlighted sections only

Question

This question has been asked several times but not in the same context as mine.

I have a beamer presentation with an initial table of contents frame for which I hide the subsections with the following code:

\begin{frame}{Outline of talk}
    \setcounter{tocdepth}{1}
    \tableofcontents
\end{frame}

\setcounter{tocdepth}{2} 

In addition, I have a highlighted table of contents before each section, using the following code:

\AtBeginSection[]
{
    \begin{frame}[noframenumbering]
        \frametitle{Table of Contents}
        \tableofcontents[currentsection]
    \end{frame}
}

My question: how to hide the subsections for all except the highlighted section in this at begin section slides.

Answer 1

Ok, this was an easy one by simply using hideothersubsections option, like this:

\AtBeginSection[]
{
    \begin{frame}[noframenumbering]
        \frametitle{Table of Contents}
        \tableofcontents[currentsection,hideothersubsections]
    \end{frame}
}
