Why cannot my android phone cannot display webpage sent from ESP8266 ?

Postby magnetron » Thu Feb 23, 2017 6:54 pm

hello dear forum,

the below webpage is sent from ESP8266 to the WinXP PC
( the picture is a bit old - in the meantime I developed the same webpage and included HTML checkbox )

Image

however when I want to see the same webpage from my android phone
following error displayed
------------------------------------------
192.168.1.110 doesnot work - 192.168.1.110 sent an invalid response
ERR_INVALID_HTTP_RESPONSE
-------------------------------------------
however when I also direct the ESP 8266 message traffic to the serial port of PC
I can see the internet package sent from android going to and coming from ESP8266 on hyperterminal

why I cannot see the webpage on my android phone ( chrome browser )?
( I type 192.168.1.110:1024 )

thanks

Seems like you are sending an invalid HTTP header to the phone.
Does the exact same thing work good with a PC?
Also, make sure that content length parameter in header is correct, all data is base64 compatible (non-text data is not allowed in HTTP!)
Also, make sure no random double-newline characters are present. That marks the end of HTTP header and may result in early termination of header by mistake.
