HTTPS GET request - ESP8266 - ENC28j60 #5
Comments

Hello! The EthernetLarge library doesn't compile on the ESP8266, and more importantly doesn't support the ENC8j60 module. You'll want to replace EthernetLarge with a library that supports your module, such as UIPEthernet. I went ahead and modified the EthernetHTTPS example sketch to work with UIPEthernet: /*
Web client
This sketch connects to a website (http://www.arduino.cc/asciilogo.txt)
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13

}In order to run this sketch you'll need to update SSLClient to v1.4.4 and install the UIPEthernet library. I don't have the hardware to test the sketch, but I was able to compile it without issues. Let me know if it works! On another note, it looks TLS over ethernet is being integrated into the ESP8266 core: esp8266/Arduino#6680, so in the future you won't need SSLClient. Oh well. |

Hi prototypicalpro, thanks for your fast response, now I have the 1.4.4 version (Downloaded from https://www.arduinolibraries.info/libraries/ssl-client). With the new library <UIPEthernet.h> it works ok, I can connect with my LAN network and I have an IP but when I try connect with the server "if (client.connect("jsonplaceholder.typicode.com", 443)) {" using SSL conection I receive an error in the Serial Monitor, I reduce the code to understand it better, my code is below: NOTE: when I compile this code to my NodeMCU 1.0 (ESP-12E Module) I receive this message: ATTENTION: The SSLClient-1.4.4 library is intended to run on samd architecture (s) and may be incompatible with your current card which runs on esp8266 architecture (s). `#include <SPI.h> byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; EthernetClient base_client; void setup() { if (client.connect("jsonplaceholder.typicode.com", 443)) { } void loop() { The Output in my Serial Monitor is: Started When I change the line to connect with the server by this, I can connect with the page: "if (base_client.connect("jsonplaceholder.typicode.com", 80)) {" Then my ENC28j60 is working ok with the ESP8266 and I can query a web service using HTTP. //------------------------------------------------------------------------------------------------------------------------// DHCP assigned IP 192.168.1.104 disconnecting. ets Jan 8 2013,rst cause:4, boot mode:(3,6) wdt reset disconnecting. //---------------------------------------------------------------------------------------// I dont know why my microcontroller is restarting with your example. Thanks for your help friend. |

That's interesting. The code where the SSLClient is failing is here (SSLClient.cpp:21): ...
const bool connect_ok = get_arduino_client().connect(host, port);
if (!connect_ok) {
m_error("Failed to connect using m_client. Are you connected to the internet?", func_name);
setWriteError(SSL_CLIENT_CONNECT_FAIL);
return 0;
}
...All ...
if(!base_client.connect(host, port))
...However this would suggest that your test Could you try running |

Hi my friend, // ---------- Code: void setup() { if (base_client.connect("jsonplaceholder.typicode.com", 443)) { } else { // ---------- Response in serial port: 400 Bad RequestThe plain HTTP request was sent to HTTPS portcloudflare This is normal because the UIPEthernet send this information (Get request) in HTTP way, so this request can't arrive in the 443 port (https port). Thanks for your help my friend. |
|
Alright, so we know for sure that UIPEthernet is not the problem. I made some changes and released v1.4.6, could you update SSLClient and give the sketch I sent you another shot? |
|
Hi friend, I've uploaded your code, only I've commented this line Ethernet.init(10); all the code is equal. This is what I'm receiving in my serial port: //----------------------------------------------------------------------- Initialize Ethernet with DHCP: User exception (panic/abort/assert)
ctx: sys ets Jan 8 2013,rst cause:2, boot mode:(3,6) load 0x4010f000, len 1392, room 16 Initialize Ethernet with DHCP: disconnecting. |

Alright, so Unfortunately, since this was a design choice, reducing the memory usage of SSLClient is not an easy fix. I can do some additional investigation of this issue, however your best bet is probably going to be to wait for this pull request to the ESP8266 core which will add support for SSL to all network interfaces. I will add a note to the README that the ESP8266 is not supported until I can address this issue. Sorry I couldn't be of more help. Send me an update if you make any progress. |

hello, i am facing the same problem after 4 years. no idea how to improve it. any ideas? |
Hi, I'm traying to compile the SSLClient library in my ESP8266 but I have this message:
Several libraries were found for "EthernetLarge.h"
using: /home/xx/Arduino/libraries/EthernetLarge-master
Several libraries were found for "SSLClient.h"
using: /home/xx/Arduino/libraries/SSLClient
Several libraries were found for "SPI.h"
using: /home/xx/.arduino15/packages/esp8266/hardware/esp8266/2.6.3/libraries/SPI
exit status 1
Error compiling for card NodeMCU 1.0 (ESP-12E Module).
I'm wanna use the SSLClient library to query a HTTPS web service using an ESP8266 (NodeMCU 1.0 ESP-12E) with a ENC28j60 (Ethernet module), I wanna know if this is possible.
Thanks.
