It was the serial communication where I finally found that, I had to replace<em> &#39;Serial&#39; </em>as<em> &#39;Serial1&#39;,</em> in places like<em> &#39;Serial.begin(9600)&#39; --&gt; &#39;Serial1.begin(9600)&#39;</em>. So try checking on that basis too, whether you had to alter anywhere in the code.</p><p>&nbsp;</p><p>I hope you will also find a resolution soon, If not please post an update here with the code, circuit diagram such that the community can guide/ help.</p><img src="https://community.element14.com/aggbug?PostID=5387&AppID=206&AppType=Weblog&ContentType=0" width="1" height="1">
