Test cases

Refer ESP32FTP_FILE_TRANSFER_ETHERNET_LAN8720.ino for full functionality

1. Transfer 5MB Size of .bmp File from Rpi FTPServer to SD Card. Check SD Card image in PC to verify Same File with Complete image is Stored or Not. Check Time Required to Copy. Repeat above transfer with Mobile Phone App. (Check this all - 3 Times)

2. On Every Key Press Read 500 byte from file into buffer and Send it on UART till file Completes and start again. (Check this - 3 Times)

3. Read file from in Between , I.e. Start Byte Address = 20,000, read till End of File and Cross Check the UART data with Data in File on respective Address. (Check this - 3 Times)

4. On Press of Key, Save one long Global Variable ( File Pointer ) and one unsigned int variable into MCU Internal EEPROM memory. At each power ON, it should read data from EEPROM and Store into concern variable.
