Failed miserably. It all looked ok, and connections seem good, but flash can’t be detected. It seems we are close to identification of the cause of the problem, but stuck waiting for result from Espressif side.</div><div><br class=""></div><div>On the firmware side, all major components are in place. Only real outstanding issue is the modem/wifi connection reliability. Also auto-OTA flash from the SD card (when the hardware SD card issue is resolved).</div><div><br class=""></div><div>Regards, Mark</div><div><br class=""><blockquote type="cite" class=""><div class="">On 3 Dec 2017, at 12:15 AM, <a href="mailto:mr23@comcast.net" class="">mr23@comcast.net</a> wrote:</div><br class="Apple-interchange-newline"><div class="">
