ESP-01 AP Mode - Can't send data back to client
Posted: Thu Oct 29, 2015 8:21 amHi, I have also posted this on Espressif's site... but no answer yet....
I have an ESP-01 - for now, connected directly to my pc via FT232RL for debugging.... but will eventually be controlled via a Teensy LC...
I have set the ESP up as an AP and can successfully receive GET requests from a web browser attaching to it.... when I receive the GET, I am recording the remote IP and Port from the client.
When I try to send data back (your typical <html></html>), it says it successfully sent it, but nothing shows up on the web browser.
Here is the UART log....
I am using Safari on my iPhone as the web browser.... its odd, because after I do the CIPCLOSE, the web browser seems to send another request using the next port..... Don't understand that.
Thanks for any and all help !
