i assume you're doing serial monitor. can't use escape sequences \r in serial monitor entry box. enter evaluated string of separate ascii characters; \r backslash character followed lowercase r. send http request, make serial monitor send \r\n you.

  • first set serial monitor both nl & cr permanently; serve commands , http requests appends \r\n send.
  • count number of bytes in http request, including carriage return , newline characters. count 61 characters in request.
  • use count in at+cipsend
  • the first line of request, , stop right before first \r\n, , click send. because of setting, monitor send typed \r\n suffixed it.
  • type , send each line of request, sent first line, until you've sent last line.
  • since there additional \r\n after last line, click send again, without typing anything. , since module requires \r indicate end of data packet, click send 1 last time.
