I have found this line in core 2.4.1 ip != 0 wrong@glue-esp/lwip-esp.c:757 but I don't know for what is it.

for moment I go back to core 2.4.0 and testing the same program once again.

Edit:
I think I have found. after 2h my router change the IP adress for ESP
I get debug message with core 2.4.0:

@TakiKroSmaN without a MCVE sketch it is unlikely this will be looked at. This was required as art of the issue template. Can you provide it?

TakiKroSmaN · 2018-04-02T09:05:46Z

@devyte Sure please find below part of the sketch. I removed SSID, password, and keys for api so adresses in HTTP functions are not correct :)
I think my problem is solved. Solution was just to assign IP to MAC in router. Otherwise my router after 2h (settings of my router) restart IP assignet and my ESP from 192.168.0.120 goes to something like 192.168.0.10x by this time for a second ESP IP adress was 0.0.0.0 and trigger function IP!=0 which crash ESP
I found it by using core 2.4.0 - at the end of previous post is an info about it.

sorry for language mix below :)

These wrong@ and STUB message are on me. At least IP static management needs revisiting in lwip2.
@TakiKroSmaN you can try with 2.4.1 or git version and lwip1.4 in the meantime.

Markusenz · 2018-04-17T20:02:57Z

I have the exact same issue here. Problem is that in 2.4.1 there is an issue when configuring a static IP:
My ESP8266 is connecting with static IP, but in the background it makes a DHCP DISCOVER request to my router for a reason I do not understand. This takes place at the moment of WiFi.Begin().
my code:
WiFi.mode(WIFI_STA);
WiFi.config(ownip, gateway, subnet);
WiFi.begin(ssid, password);
The ESP8266 connects correctly with static IP 192.168.6.245, but at the same time it send DHCP DISCOVER. My router replies by offering 192.168.6.117 with a lease time of 10 minutes.
The ESP then is responding to the static IP 192.168.6.245. However, after exactly 10 minutes (DHCP lease timeout), it crashes with debug message

ip != 0 wrong@glue-esp/lwip-esp.c:757
...

This needs to be fixed, should be a problem for many users !?

d-a-v · 2018-04-17T22:34:06Z

Can you please try this, assuming you are using git:

cd tools/sdk/lwip2
make download
cd builder
git checkout master
cd ..
make install

and check again for this issue ?

Markusenz · 2018-04-18T01:24:15Z

I tried that lwip2 update. The ESP crashes depending on the order of WiFi.config() and WiFi.mode(), see below.
The DHCP requests are still being sent, every 5 minutes, although I use static IP.

With this code the ESP crashes:

#include <ESP8266WiFi.h>
#include <ArduinoOTA.h>

const char* ssid = "xx";
const char* password = "yy";
IPAddress ownip(192,168,6,245);
IPAddress gateway(192,168,6,5);
IPAddress subnet(255,255,255,0);

void setup() {
 Serial.begin(74880);
 delay(1000);
 WiFi.config(ownip, gateway, subnet);  
 WiFi.mode(WIFI_STA);  
 WiFi.begin(ssid, password);
 ArduinoOTA.onStart([]() {
   Serial.println("Start");
 });
 ArduinoOTA.onEnd([]() {
   Serial.println("\nEnd");
 });
 ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
   Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
 });
 ArduinoOTA.onError([](ota_error_t error) {
   Serial.printf("Error[%u]: ", error);
    if (error == OTA_AUTH_ERROR) Serial.println("Auth Failed");
    else if (error == OTA_BEGIN_ERROR) Serial.println("Begin Failed");
    else if (error == OTA_CONNECT_ERROR) Serial.println("Connect Failed");
    else if (error == OTA_RECEIVE_ERROR) Serial.println("Receive Failed");
    else if (error == OTA_END_ERROR) Serial.println("End Failed");
   });
 ArduinoOTA.begin();
}

void loop() {
 delay(50);
 ArduinoOTA.handle();
}

the ESP crashes after first boot, outputs some garbage, and after restarting itself, it seems to run the sketch:

interestingly, when I exchange the wifi.mode and wifi.config commands to the following order:

  WiFi.begin(ssid, password);

the ESP runs ok without crashing. However still sending DHCP requests.

lrmoreno007 · 2018-04-18T02:13:57Z

First set the STA mode. After this set the config and then begin(). It's the standard order.

Fixed IP need less time than DHCP, for DHCP you need insert this lines for wait connection result just after begin (with fixed IP it is also advisable) :
while (WiFi.status() != WL_CONNECTED) {
delay(500);
//Serial.print(".");
}

In your sketch, with your order you are configuring STA + SoftAP (see debug message), and after this you are destroying it with mode(WIFI_STA)

Regards

d-a-v · 2018-04-18T08:53:19Z

@Markusenz
While @lrmoreno007 is right, your sketch as-is is working here (no crash, static IP).
The DHCP request is indeed sent but that's because of your delay(1000) and this interpretation.
Without your delay, the dhcp request is not sent.
To be sure, I even changed my dhcp server's lease time to 1mn. Not any one is coming without your initial delay.
Can you please double check ?

Markusenz · 2018-04-18T11:30:56Z

Thank you! When removing the delay, DHCP seems completely turned off now, I do not see any requests now. With the right order of WiFi.. commands, all is working now.

However, I could reproduce the crash of the above mentioned sketch (doing WiFi.config() first) on another Arduino installation, also with 2.4.1 core, however this one still uses the original lwip2 version from the 2.4.1 installation.
(code as above, but removed the delay now).The output:

I don't know if this issue is relevant since the order of Wifi commands seems to be unusual, but its not documented anywhere I think. When inserting the check of WiFi.status() as @lrmoreno007 mentioned, I get a stack trace with the crash:

Would you be able to try this other sketch/installation with the current git version of the core (and with the lwip2 update from above) ?

lrmoreno007 · 2018-04-18T18:07:35Z

First of all, are you using a static IP in the DCHP range of your router?

In the other hand, surely you are using "Erase Flash : All Flash Content", then this is what occurs:

first start after upload the ESP start as AP
with config() you set STA+ AP, config STA+AP and disable DHCP
with mode() kill STA+AP and set STA but without configured IPs (don't know how DHCP state is).
with begin() you connect to WiFi.
then a WDT reset occurs

After WDT reset, ESP start as STA and everything work fine, at least for me.

It happens more or less the same with the order that I told you (as we can see in your feedback), but it's the correct order.

You can check all this by inserting WiFi.printDiag(Serial) after each instruction:

  WiFi.printDiag(Serial);
  WiFi.config(ownip, gateway, subnet);
  WiFi.printDiag(Serial);
  WiFi.mode(WIFI_STA);
  WiFi.printDiag(Serial);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.println(".");
  }
  WiFi.printDiag(Serial);

Thanks @lrmoreno007, now I understand whats going on with DHCP. No, the static IP is not taken from the DHCP server's range.

I could reproduce the crash on another machine with latest versions, however as mentioned the crash only happens when issuing WiFi.config() before WiFi.mode() so it can be avoided.
crash log:
