3 brand new ESP WROOM-32s all have no WiFi connectivity.....
Posted: Sun Dec 24, 2023 10:34 pm
Hello,
I was wondering what available troubleshooting is available to determine why an ESP processor is not connecting to
a local area network. I have used ESP WROOM-32s for a couple years and they normally work without any issues.
But I just received 3 new ones that look identical to my existing units and none of these will establish a network connection.
The same code works fine in my existing ESPs and a simple onboard LED blink loop works fine on the newest ESPs.
One area I am unsure about is the selecting the proper board assignment in my Arduino IDE. I have always found the
"WROVER Module" board assignment works first time everytime.There are a multitude of others available
like the ESP32-WROOM-DA-Module and WROVER Kit (all versions) but they seem to have issues that the WROVER
Module does not present.
Any leads, links, or suggestions are appreciated.
Thanks....
p.s. the picture shows the new ESP32 on the right and the older one on the left. They appear identical.
