Topic: ESP32CAM with Mega

Hi

My problem is : no wifi connection
Question : how to support ESP32CAM ? or "how to debug to see the mistake"

Board : A photo resistor is connect to arduino and a ESP32CAM for wifi. (IOT with cloud)
Smartphone skin : switch for BUILTIN_LED, jauge and text for display luminosity

I
- followed tutorial for setting software serial at 19200 on pins 10 & 11 (respectly connected to Tx and Rx of ESP32CAM)
- added debug information via (hard)Serial to see luminosity value : my Mega working !!
- looked on my dedicated AP Wifi : no client (working with smartphone)
- used ESP32CAM without Remote and that work (with an other sketch of course)
- finally tried to used a strap between Gpio0 and GND during upload sketch via Arduino IDE, and one minute after remove it, and reboot (unplug and replug the 3,3v on ESP)


I precise i'm technology teacher but newbie with remoteXY (why this name?)

thanks for help
regards

Antoine

Re: ESP32CAM with Mega

Sorry, Esp32 as external modem for Arduino not supported.
