How to retrieve image file from SD card and send it to a phone number using GSM/GPRS module (through Arduino)

Projects Programming

Hello, I am a newbie when it comes to complex Arduino functions such as this one. Basically, I want to retrieve an image file from the SD card that was taken by a camera module (ESP32-CAM or any other alternative to a camera and micro SD card module) and then send it to a phone number using GSM/GPRS module through Arduino.

I've been researching and seeing a couple of topics and forums that say this is entirely possible, but so far, I have not seen any full tutorial on how to make this functionality work.

If anyone could provide some assistance, I would greatly appreciate it! Thank you!

Have you retrieved data from a SDcard file with an Arduino?

You should not expect to find a "full tutorial". As a beginner, you should get all the parts working individually, and make sure you understand how each part works, before even thinking about combining them.

For example, learn to send one or two data items via a phone connection. Then learn how to read a file from the SD card. Finally, put together an error checking protocol that will implement file transfer and verify error-free transmission of the entire file.
