how ESP8266 send data by source code? (not by AT command)

2017-04-07T17:03:40+08:00

Hi Pratik,

Thank you!
I gave up RTOS SDK and playing with AT commands now. ESP8266 can Tx/Rx data by AT+CIPSTART and AT+CIPSEND.
My request is ESP8266 needs to send "11,!11" when she got the following example input:
---------------------
+IPD,6:deg=11
OK
--------------------

any idea to implement this by changing the source codes? (in user_main.c?)

It might be a DNS issue?
Did you try 192.168.4.2/ instead of using the domain name?
