- Sat Jan 21, 2017 5:32 am #61303 hello all,
i have downloaded the esp-8266 and tried that.
with very much reading and searching i am able to run the code successfully up to the point where i get dhcp ip and data, cats and links are also visible at browser, but still it i don't understand how can i send and receive data to a static ip server ex 117.218.36.237 is the ip and port is 587 i wan to send data to this one how to proceed ????

i have following: in the com port and it then keeps on showing heap:........

Code: Select allInitialise ENC stack, dhcp if requested

Init ENC

Hi ankurjadon,

This project doesnt make external connections, it just serves Sprites esphttpd over wired and wifi - which you have now got working. I haven't had time to add extra functionality as yet.

It'll be a bit of work to figure it out from your side, but to make connections, you'll need to create a TCP 'application' in stack.c, and then handle all further packets from there. Remember if you're initiating a connection then you need to start the connection with a SYN packet, wait for the SYN ACK etc etc.

thanks for quick response. i understand what i need to do now.
i am a complete beginner at this tcp stuff but i will try to implement this for external SERVER IP. and update in next post.


thanks alot.

Hi All!

UIPEthernet arduino library ported to ESP8266.
This library have compatible API with Wiznet W5100 Ethernet library.

I uploaded modified UIPEthernet library to https://github.com/UIPEthernet/UIPEthernet
I modified the following:
- Set the version to 1.1.0
(This version tested on ESP8266 too. Working properly. Without watchdog resets.)
- Correct ESP8266 exception(28).
- Add watchdog reset calls in functions for stable running on ESP8266.
- Add geterevid function to get ENC28j60 chip erevid (revision information).
- Change linkStatus to static for outside call.
- Add functions bypass, if can't communicate with ethernet device.
- Add SPI bus instabil communication detection.
- Change debuging/logging. Remove individual debuging. Add global and scalable debuging feature.
You can setup debuging/logging level in utility/logging.h
You can use this header file in Your scetch too.
Add "LogObject" define for serial logging/debuging with board specific default setting.

Best Regards

Hello,

I am a bit novice... and I hit a wall of disappointment. If I upload any example from the UIPEthernet library my ESP 12E goes into RST Cause 2. Could you recommend me a solution?

Thanks in advance
