 &lt;p&gt;We came up with a list of functions every device –no matter how distinct– must support, and we created an interface called &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;DeviceProtocol&lt;/code&gt; that encompasses all these functions. Our interface will include functions like &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;SetDeviceConnection&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;SetLogger&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Read&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Write&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;GetIMEI&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;SetUnit&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Acknowledge&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Reject&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Handle&lt;/code&gt;, &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;StoreRecord&lt;/code&gt;, and &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Disconnect&lt;/code&gt;.&lt;/p&gt;
