<p dir="auto">I need some help with ESP-IDF in a Atom Lite. I have two version of Atom Lite and one of Stick C.</p>
<p dir="auto">One version of Atom Lite has a label with the text "Adding Model-ATOM-2" with FCC details, the other version has a label with text "NOTE".</p>
<p dir="auto">See Photo: <a href="https://pasteboard.co/JlJHMAW.jpg" target="_blank" rel="noopener noreferrer nofollow ugc">https://pasteboard.co/JlJHMAW.jpg</a></p>
<p dir="auto">My program, designed with ESP-IDF, works perfect in Atom Lite with label "Adding Model-ATOM-2" and "ESP32 DevKit-C" but when I use the Atom Lite with label "NOTE" or Stick C, the wifi disconnects when registering with AP. Sometimes I can get a stable connection, but after many many tries and time.</p>
