Sending data from Arduino Mega to ESP32 cam

Projects Programming

Hello Everyone,

I am using Arduino mega with all my sensors connected to it. I want to upload the data of these sensors to Google Firebase server. I have an ESP32 cam board in my project, and it is already connected to my firebase server in order to retrieve the camera's IP address in my mobile application. I am asking that how can I send the sensors' data from Arduino mega to ESP32 cam, so I can upload them to my server.

You can check my project from here: Guardian of The Earth
This thread explained well my problem. However, I didn't get the answer from it. [HELP] Serial Communication between an ESP32-CAM and Arduino Mega2560 - Programming Questions - Arduino Forum

Details on how to use the additional UARTs that the ESP32CAM supports are included in that thread.

See Message #6 for instance.
