- Tue Jan 17, 2023 1:18 pm #95830 Hello! I'm totally new here and attempting to build the propane poofer which utilizes the Thing Dev built-in server capabilities to establish a wifi connection & web page interface to trigger the poofer. It's uploaded and wired up... all the relays, switches and solenoids respond appropriately to clicks on the poofer control web page as expected when Thing is connected to my computer's usb port. BUT... when i disconnect the USB power to connect Thing to a portable battery the unit stops broadcasting it's wifi network SSID to which I need to connect to control the poofer.

Does this board need constant power? I assummed that once the code was uploaded that this board would servecand broadcast its own network whenever it is powered on. But it seems like it loses this ability if power is interrupted.

Sorry for the delay in replying to you. I did not get an email notification alerting me to your reply to my query.

Regarding your question, I unplug USB power first, then connect to portable battery. I figured since the code was flashed to the memory on the Thing Dev that it would survive being unplugged from power and subsequently reboot its program upon being reconnected to power. Could it be something in the Sketch that I uploaded that somehow breaks its ability to reboot and broadcast its wifi network once powering up again?
