How can I send .zip file with I2C? Can you give me an example? Examle I'm trying send string text but I can't send more than 32 characters.
You can send more than 32 bytes in ONE GO by changing the buffer size in the Wire.h Library. Note that I2C is a byte oriented protocol; it always sends one byte in one transmission frame.
Are there other alternatives? How can I send and receive data(.zip or .rar) between two computers through arduino?
use computer networks to transmit data between computers, not Arduino.
For security, I don't want to share data over the network. That's why I chose arduino. There was no other way? Can't send data over Arduino?
