When using AT+CIPSEND= command e.g. AT+CIPSEND=0,5
and then sending data e.g. ABC\r\n chip reads only 4 chars and after next char e.g. A is send to chip message ABC\nA is send to destination instead of correct ABC\r\n. So it is impossinble to send e.g. standard http reponce message becuse http message header lines must end \r\n combination.

So AT command / chip firmware "eats" / discards every \r chars on AT+CIPSEND command message payload. I tested this even multiple \r\r\r payload messages and every \r char is ingnored.

Firmware & AT command versions info:
AT+GMR
