void setup() {
    WiFi.mode(WIFI_STA); 
    Serial.begin(115200);

The same example compiles ok with esp8266.

[tablatronix]

What esp32 lib version?

[tablatronix]

The arguments were changed for events in new idf, The S2 branch should have a fix already

[bkrajendra]

Yes. Got it working using S2 branch. But still not showing of AP. Need to test more. will get back once I get enough testing.

[rlhelinski]

For me, the fix was to revert to version 1.0.6 of the esp32 board package rather than trying to use 2.0.0.

[tablatronix]

Can you test the S2 branch, I am about to merge it when I know its not breaking anything, should work for all sdk versions

[rlhelinski]

I can try. Is there a way to get a git clone (with a particular branch checked out) in the Arduino IDE?

[tablatronix]

Yes of course, but it can be a pain, dont worry about it then.

I have the issue when trying to compile mainlessmesh on an ESP32S2 dev boartd . The wifi.h complains

[tablatronix]

are you using latest git? should be fixed in master, ill push a beta right now

[ccadic]

yes. latest Painless_Mesh (yesterday's version) latest arduino IDE (yersterday's stable version). Looks like the issue is in wifi. shall I load the wifimanager from this git ?

[tablatronix]

I just pushed v2.0.5-beta

[star297]

Using WiFi events,

  WiFi.onEvent(WiFiConnected, SYSTEM_EVENT_STA_CONNECTED);
  WiFi.onEvent(WiFiGotIP, SYSTEM_EVENT_STA_GOT_IP);
  WiFi.onEvent(WiFiLostIP, SYSTEM_EVENT_STA_LOST_IP);
  WiFi.onEvent(WiFiDisconnected, SYSTEM_EVENT_STA_DISCONNECTED);

Working on version 1.0.6

Get this on version 2.0.1

no matching function for call to 'WiFiClass::onEvent(void (&)(arduino_event_id_t, arduino_event_info_t), system_event_id_t)'

Do I just use 1.0.6 until fixed? or is there a different method to use wifi events?

[zekageri]

Same problem with etnernet:

void ethEvent(WiFiEvent_t event){
    if( event == SYSTEM_EVENT_ETH_START ){
        ETH.setHostname(hsh_fileSystem.config.hostname);
    }else if( event == SYSTEM_EVENT_ETH_GOT_IP ){
        Serial.printf("\nConnected to Ethernet\n");
        Serial.printf("NS - IP:\t%s\n",          ETH.localIP().toString().c_str());
        Serial.printf("NS - MAC:\t%s\n",         ETH.macAddress().c_str());
        Serial.printf("NS - Host:\t%s\n",        ETH.getHostname());
    }else if( event == SYSTEM_EVENT_ETH_DISCONNECTED ){
        Serial.println("\nNS - Ethernet disconnected");
    }
}

Compiler warnings about comparison between 'enum arduino_event_id_t' and 'enum system_event_id_t' and crash when got an event interrupt.

If i replace the system events ( that i used before without problem ) like SYSTEM_EVENT_ETH_START, SYSTEM_EVENT_ETH_GOT_IP and SYSTEM_EVENT_ETH_DISCONNECTED with the new ARDUINO_EVENT_ETH_START, ARDUINO_EVENT_ETH_GOT_IP and ARDUINO_EVENT_ETH_DISCONNECTED i also got a crash but different:

[tablatronix]

There is a check in there to use the correct events, perhaps it is not working on your enviroment? What version of IDf are you using, are you using arduino ?

[Chicco7]

Hi, about the problem of "onEvent" in the 2.0x framework I found this: https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiClientEvents/WiFiClientEvents.ino Use "ARDUINO_EVENT_WIFI_STA_DISCONNECTED" for the WiFi disconnection event. (Follow the link for the other event). For me it work fine

[zekageri]

It was my bad. Iam using arduino esp32 but i used some old version and the spinlock_acquire crash was about some other part of my program. The new events working fine.

[zekageri]

So. I updated the package and the the ETH events but my esp do not get a gotip event sometimes. It looks like when i perform a software restart, only the connection event fires, but not the gotip event. The esp is connected and got an ip however

[tablatronix]

that sounds like the esp32 double hitter bug
