ESP32-C3 WiFi connection error

The ESP32-C3 WIFI connection code I am using is:

var wifi = require("Wifi");
var ssid = 'FOFStudioWifi';
var password = 'FOFStudioWifiQQ';
wifi.connect(ssid, {password: password}, function() {
    
});

The ESP32-C3 firmware I am using is:https://www.espruino.com/binaries/travis/master/

Due to my poor English, it is often difficult to ask questions; Please help us answer this question
Thank you again to the ESPRUINO community

I am definitely not an Espruino codebase nor an ESP32 expert, but from what I see in the source, it seems that a null pointer is passed to jsvUnLockInline --> https://github.com/espruino/Espruino/blob/ff487e008472deff8113a32ebd3217dbd606405c/src/jsvar.c#L860

It won't help you directly, I'm sure, but it might help others identify your problem and guide you to a solution.

Hello, thank you for your answer. We have just started researching ESPRUINO, and it may be a bit difficult to compile the firmware ourselves

If you compile by yourself it will allow you to generate an ELF file, that you can use following this quick explanation to have more clue on what is happening

We have been troubled by this issue for some time now, and we hope that technical experts can provide updates to solve the WiFi problem
I sincerely hope that ESPRUINO can flourish and we will also donate to ESPRUINO in the future

Thank you for your answer. Although I currently do not have the ability to compile firmware; But still thank you for your answer; I will try my best to wait and see if there are any technical experts who can help solve this problem

For the time being, if you need to use Espruino with WiFi on ESP32, I strongly recommend you to use one version of the chip which is already well supported (see this table, 1st column)

Thank you for your answer. The main reason is that our company currently chooses the ESP32-C3 board; And currently, ESPRUINO happens to support this board; That's why I chose ESPRUINO.
ESPRUINO is a very good product, and I hope some experts can take a look at the WiFi issue with C3

Espruino doesn't officially support ESP32-C3, everything which is provided is gracefully brought by @Gordon and the community. It may take several months until a stable firmware can be deployed on ESP32-C3. That said, if your company is keen to support Espruino, you could find a way on this page: http://www.espruino.com/Business

Hi @user158605 this is a known issue, check the workaround for this.

Hi, thank you for your answer. However, the WiFi connection code did not trigger a callback

After our verification, the wifi is indeed unable to connect, and there is no callback output when connecting to wifi; It seems that we can only wait for @Gordon to take a look

In this case I guess you are already connected, check with wifi.getState()

Thank you for your answer. We have tested it; Command cannot be used correctly
We also checked the connection information of the router and did not see any devices successfully connected

var WIFI_NAME = "123";
var WIFI_OPTIONS = { password : "123456789" };

var wifi = require("Wifi");
wifi.scan(function (err, networks) {
    console.log(err, networks);
    wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
      if (err) {
        console.log("Connection error: "+err);
        return;
      }
      console.log("Connected!");
    });
});

setTimeout(function() {
  console.log(wifi.getState());
},4000)

I just took a quick look at this - I'm afraid I don't have much time now.

Has anyone else got WiFi working? I'm sure I did test this originally and it worked, so I'm not sure what's up....

Compiling with the WiFi info (commenting out esp_log_level_set("*", ESP_LOG_VERBOSE)) and enabling jsDebug I see:

So it's actually just not connecting as far as I can tell (rather than Espruino having some issue and not reporting it).

To try and get enough space in the IRAM I did change some things in targets/esp32/IDF4/sdkconfig_c3 - possibly CONFIG_ESP_WIFI_IRAM_OPT based on https://docs.espressif.com/projects/esp-idf/en/stable/esp32c3/api-guides/performance/ram-usage.html#optimizing-iram-usage - and I wonder if that affected Wifi stability?

BUT PLEASE STOP POSTING THE SAME THING MULTIPLE TIMES - just post a new thread (like this) for each issue you encounter. The more duplicate things I have to go through the more time is wasted that I could be using fixing stuff

It is definitly working! This is also an issue on ESP32 devices and even with earlier IDF version like 3.x.

Edit:

Ok, this is only true for ESP32_IDF4

ESP32C3_IDF4 latest build does not connect anymore to an AP

Event-> disconnected: {.......,"reason":"2","msg":"AUTH_EXPIRE"}

Try this

// Test ESP32 WiFi event callbacks
var ssid="<SSID>";
var password="<PASSWORD>";

var wifi=require("Wifi");

wifi.on("associated", function(details) {
	console.log("  Event-> associated: " + JSON.stringify(details));
});
wifi.on("connected", function(details) {
	console.log("  Event-> connected: " + JSON.stringify(details));
});
wifi.on("disconnected", function(details) {
	console.log("  Event-> disconnected: " + JSON.stringify(details));
});
wifi.on("auth_change", function(details) {
	console.log("  Event-> auth_change: " + JSON.stringify(details));
});
wifi.on("dhcp_timeout", function(details) {
	console.log("  Event-> dhcp_timeout: " + JSON.stringify(details));
});
wifi.on("probe_recv", function(details) {
	console.log("  Event-> probe_recv: " + JSON.stringify(details));
});
wifi.on("sta_joined", function(details) {
	console.log("  Event-> sta_joined: " + JSON.stringify(details));
});
wifi.on("sta_left", function(details) {
	console.log("  Event-> sta_left: " + JSON.stringify(details));
});

level = 0;
wifi.stopAP(()=> {
  level ++;
  print("I stoped AP", level);
  wifi.disconnect(()=>{
    level ++;
    print("II disconnect station", level);
    wifi.connect(ssid, {password: password}, function() {
      level ++;
	    console.log("III Connect completed", level);
    });
  });
});

Has anyone else got WiFi working? I'm sure I did test this originally and it worked, so I'm not sure what's up...

Yes it worked before, but now its broken for ESP32C3_IDF4

Yes, we have been testing for a long time; It has indeed been effective; Unable to connect properly

Check my recent update on https://forum.espruino.com/conversations/395499/?offset=125#comment17502762

Are you using "supermini" boards? It seems these boards are just broken and WiFi doesn't work reliably on them. But if not, using wifi.stopAP() first (or using the latest build that does it automatically) may help
