ESP32 WROVER to ESP32 WROVER TCP connection not working
Posted: Thu Apr 26, 2018 11:43 am
Hi,
Is there a specific sequence of steps to follow to setup a TCP connection between two ESP32 WROVER modules?
I have done the following without any success.
On the SOftAP side:
AT+CWSAP="MyName","password",5,3
AT+CIPAP = "192.168.4.10","192.168.4.20"
AT+CWMODE=3
AT+CIPMUX=1
AT+CIPSERVERMAXCONN=4
AT+CIPSERVER=1,2000
AT+CIPSTO=3600
On the client (STA) side:
AT+CWMODE=3
AT+CIPMUX=0
AT+CWJAP="MyName","password"
(the above responds with WIFI CONNECTED and GOT IP)
AT+CIPSTART="TCP","192.168.4.10",2000
The code returned is "connect fail,ret=-1 error=113 ERROR".
Any suggestions or examples using AT commands to establish a connection would be greatly appreciated.
Thank you.
