+<p>The function <b>ARM_WIFI_SocketAccept</b> accepts a connection request queued for a listening socket. If a connection request is pending, <b>ARM_WIFI_SocketAccept</b> removes the request from the queue, and creates a new socket for the connection. The original listening socket remains open and continues to queue new connection requests. The <em>socket</em> must be a socket of type <b>ARM_SOCKET_SOCK_STREAM</b>.</p>
+<p>In blocking mode, which is enabled by default, this function waits for a connection request. In non blocking mode, you must call the <b>ARM_WIFI_SocketAccept</b> function again if the error code <code>ARM_SOCKET_EAGAIN</code> is returned.</p>

+<p>The argument <em>ip</em> is a pointer to the buffer that will receive the IP address of the connection node. If the <em>ip</em> is <span class="XML-Token">NULL</span>, the IP address is not returned.</p>
+<p>The argument <em>ip_len</em> is a pointer to the IP address length. It should initially contain the amount of space pointed to by <em>ip</em>. On return it contains the actual length of the address returned in bytes.</p>

+<p>The function <b>ARM_WIFI_SocketConnect</b> assigns the address of the peer communication endpoint. The function behaves differently according to the type of socket:</p>
+<ul>
+<li><p class="startli"><b>ARM_SOCKET_SOCK_STREAM:</b> A connection is established between the endpoints.</p>
+<p class="startli">In blocking mode, which is enabled by default, this function waits for a connection to be established.</p>
+<p class="startli">In non blocking mode, the function returns the error code <code>ARM_SOCKET_EINPROGRESS</code> and the connection is established asynchronously. Subsequent calls to <b>ARM_WIFI_SocketConnect</b> for the same socket, before the connection is established, return the error code <code>ARM_SOCKET_EALREADY</code>. When the connection is established, the call to <b>ARM_WIFI_SocketConnect</b> returns the error code <code>ARM_SOCKET_EISCONN</code>.</p>
+</li>
+<li><p class="startli"><b>ARM_SOCKET_SOCK_DGRAM:</b> An address filter is established between the endpoints.</p>
+<p class="startli">The address filter is changed with another <b>ARM_WIFI_SocketConnect</b> function call. If the socket is not yet bound, the system implicitly binds to a random dynamic port.</p>
+</li>
+</ul>
+<p>The argument <em>socket</em> specifies a socket identification number returned from a previous call to <a class="el" href="group__wifi__socket__gr.html#ga1433b297315ab394f1544a18548ffcc6">ARM_WIFI_SocketCreate</a>.</p>
+<p>The argument <em>ip</em> is a pointer to the buffer containing the IP address octets of the endpoint node.</p>
+<p>The argument <em>ip_len</em> specifies the length of the IP address. The length is <span class="XML-Token">4</span> bytes for the IPv4 address and <span class="XML-Token">16</span> bytes for the IPv6 address.</p>
+<p>The argument <em>port</em> specifies the port of the endpoint node. If the argument <em>port</em> is <span class="XML-Token">0</span>, the function returns error, because this port is reserved.</p>
