WiFiClientSecure not working lwip mode ! (insecure) #8291
Comments
|
the service at djxmmx.net:17 doesn't support secure connection. use some https site for the test |
|
i Want to read this link : My Code : // WiFi.begin(ssid, pass);
// SPI.begin();
// while (WiFi.status() != WL_CONNECTED)
// {
// delay(500);
// Serial.print(".");
// }
// Serial.println();
//
// Serial.print("Connected, IP address: ");
// Serial.println(WiFi.localIP());Ethernet Connection : eth.setDefault(); // use ethernet for default route
if (!eth.begin(mac)) {
Serial.println("ethernet hardware not found ... sleeping");
while (1) {
delay(1000);
}
} else {
Serial.print("connecting ethernet");
while (!eth.connected()) {
Serial.print(".");
delay(1000);
}

Hello @elexal, Digging a bit deeper into the matter and debugging with the additional debug flags However, I currently use the following as a temporary workaround (before each It should query the IP from the DNS server and cache it so that the name resolution won't fail. This has worked fine so far for me. However, I haven't done much testing. Maybe someone else could double-check the described behavior and workaround. |

Dns error -5 with W5500 module.. give a look here #6212 :) |
|
Can you try with this PR #8317 ? |
|
Works as intended :) |
esp_yield() now also calls esp_schedule(), original esp_yield() function renamed to esp_suspend(). Don't use delay(0) in the Core internals, libraries and examples. Use yield() when the code is supposed to be called from CONT, use esp_yield() when the code can be called from either CONT or SYS. Clean-up esp_yield() and esp_schedule() declarations across the code and use coredecls.h instead. Implement helper functions for libraries that were previously using esp_yield(), esp_schedule() and esp_delay() directly to wait for certain SYS context tasks to complete. Correctly use esp_delay() for timeouts, make sure scheduled functions have a chance to run (e.g. LwIP_Ethernet uses recurrent) Related issues: - #6107 - discussion about the esp_yield() and esp_delay() usage in ClientContext - #6212 - discussion about replacing delay() with a blocking loop - #6680 - pull request introducing LwIP-based Ethernet - #7146 - discussion that originated UART code changes - #7969 - proposal to remove delay(0) from the example code - #8291 - discussion related to the run_scheduled_recurrent_functions() usage in LwIP Ethernet - #8317 - yieldUntil() implementation, similar to the esp_delay() overload with a timeout and a 0 interval

Closing via #7148 as well |
hello friend
we have an ESP8266 that connects to the host SSL with wifi
And we receive data from it without any problems
We have an interface Ethernet(W5500 or Enc28j60) which we want to receive data from it
If the SSL does not exist it connects to the server and receives the data with wificlient and lwip library
When we activate Setinsecure and WiFiClientSecure it doesn’t connect to the server anymore.
The server that we want to connect to by Ethernet has SSL and we have to use wificlient secure library that works without any problem on wifi , but on Ethernet mode it doesn’t connect
Codes for wifi and Ethernet are the same and are used from one library
In the following example we connect to a host by Ethernet and receive data but if we change the library from wifi client to wificlient secure it doesn’t work anymore.
`/*
This sketch establishes a TCP connection to a "quote of the day" service.
It sends a "hello" message, and then prints received data.
