AT+CIPSTART fails

Postby wimalopaan » Thu Apr 27, 2017 11:44 pm

Hi all,

every time I want to establish a tcp connection I get an error:

AT+CIFSR
+CIFSR:STAIP,"192.168.178.37"
+CIFSR:STAMAC,"18:fe:34:f4:db:5e"

OK
AT+CIPSTART=1,“TCP“,“www.heise.de",80
Link type ERROR

ERROR

I am using:

AT+GMR
AT version:1.3.0.0(Jul 14 2016 18:54:01)
SDK version:2.0.0(656edbf)
compile time:Jul 19 2016 18:44:44
OK

Any hints form me?

Pinging ist ok:

AT+PING="www.heise.de"
+21

OK

Hi,

Please try: AT+CIPSTART=“TCP“,“www.heise.de",80

1 is for multiple connection mode (AT+CIPMUX=1).

Thanks for your interest in ESP8266!
