Ouch - is this new in 3.3.6?

[MaBecker]

No, just tested a 2v09 version

Not sure what causes this?!

ESP32 is calling many times esp_wifi_connect()

https://github.com/espruino/Espruino/blob/11d2ca3a1d13cf1067c631d9bd45b343a0fed159/libs/network/esp32/jswrap_esp32_network.c#L489

https://github.com/espruino/Espruino/blob/11d2ca3a1d13cf1067c631d9bd45b343a0fed159/libs/network/esp32/jswrap_esp32_network.c#L547

https://github.com/espruino/Espruino/blob/11d2ca3a1d13cf1067c631d9bd45b343a0fed159/libs/network/esp32/jswrap_esp32_network.c#L878

ESP8266 is just calling it in jswrap_wifi_connect()

The ESP32 is calling it additionally in event_handler()

[gfwilliams]

I think there is a way of turning on some extra debug logging for ESP32? Memory errors are frustrating to debug because as there's no memory left a stack trace can't be stored.

Is it reproducible every time with that code you added?

[MaBecker]

Just build new app and esp-ifd files and the error disappeared ....... will run some more tests

[MaBecker]

Ok, it still happens ....

Was'nt this changed to use jsWarn, jsError etc. long time ago ?

workaround is call to E.reboot() and than upload the code

Edit: Do not connect if already connected

var ssid="SSID";
var password="password";

var wifi=require("Wifi");
wifi.stopAP(()=> {
  print(wifi.getStatus());
  var status = wifi.getStatus();
  if (status.ssid == ssid && status.station == "connected"){
    print(wifi.getIP());
  } else {
    wifi.connect(ssid, {password: password}, function() {
      print(wifi.getIP());
    });
  }
});

@gfwilliams: Should this be handle internaly by the wifi.connect() function? Or is handling it in JS good enough?

[gfwilliams]

The wifi.connect function should really handle this, yes. I think if it's already connected it should probably attempt to stop the connection first, as in some cases a user might want to force a reconnect to an existing AP.

You mentioned in https://forum.espruino.com/conversations/395499/?offset=125#17501763 that it might be 'broken again' so do you still think this is the issue?

When I tested here I enabled all the wifi debug messages and I didn't see any sign that the C3 had even managed to get a wifi connection before .connect was called.

[MaBecker]

fixed in the latest build.

We can use disconnect or connect with different setting.
