Invalid Event when Client connect AP + debug output

[luc-github]

Using latest Git
Using WiFiAccessPoint sample
Debug is disabled but message appear

When client connect to AP there is an unwished output:

E (28866) event: mismatch or invalid event, id=63
E (28867) event: default event handler failed!
dhcps: send_offer>>udp_sendto result 0

error messages seems come from : https://github.com/espressif/esp-idf/blob/master/components/esp32/event_default_handlers.c#L457

Debug message is from : https://github.com/espressif/esp-idf/blob/master/components/lwip/apps/dhcpserver/dhcpserver.c#L527
looks like #if DHCPS_DEBUG is missing

I know they looks like IDF issue but I only use arduino
I have opened ticket for Debug message : espressif/esp-idf#2924
But no idea what to do with other issue sorry

[me21]

I confirm, my Arduino version is 1.0.1.

[markingle]

I am having the same problem. I am unable to connect to the esp32 wifi from my Windows laptop and Mac mini. I just pulled the latest version from the arduino-esp32 repo

[me21]

This is not the same bug. I am able to connect, but I get error messages from ESP32 as a side effect.

In fact, I wasn't able to connect to ESP32 AP on the previous versions of Arduino framework (was getting authentication errors).

Related bugs in ESP-IDF: espressif/esp-idf#2916, espressif/esp-idf#2915.

They are going to fix those within 2 weeks.

[me-no-dev]

There already is a "fix" for this in arduino master, but is available to github installs only.

[luc-github]

@me-no-dev you mean esp-idf github ?

[luc-github]

@me-no-dev Yes I saw this commit but it is not same issue actually
the message is raised by ESP_LOGE(TAG, "mismatch or invalid event, id=%d", event->event_id);
https://github.com/espressif/esp-idf/blob/master/components/esp32/event_default_handlers.c#L457

not https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/src/WiFiGeneric.cpp#L342

Confirmed still present with today git test

[Aimlessisland]

Same problem here really annoying
IP address: 192.168.4.1
E (1113) event: mismatch or invalid event, id=63
E (1114) event: default event handler failed!

[chegewara]

If i remember correct event: mismatch or invalid event, id=63 is wifi mesh event and in normal wifi connection can be ignored. It was answered on esp-idf issue tracker or on forum, but im not 100% sure.

[sbarrufaldi]

I have the same problem when I try to connect to AP.

E (4302) event: mismatch or invalid event, id=63

Rebooting...

It keeps rebooting 4 or 5 times and then it connects perfectly. But for my program are 10 missed seconds...

[superfrobo]

Hi everybody, I have the same problem. Deleting all chip before programming does not solve.

Rebooting...

3 more reboots follow. then system stabilizes and event happens again at next attempt to connect.
Developing with Platformio and updated arduino framework for Esp32

Any workaround?

[b1gmans]

I also have this issue, it is serious as my project will not run as expected after the error messages are displayed:
E (27188) event: mismatch or invalid event, id=63
E (27189) event: default event handler failed!

Is there a fix for this please?
I have downloaded the latest esp32 system in my arduino ide - still no better? v1.0.1 is what Im running

Is there a way to get latest fixes that may not yet be in this official release? how? Im using windows 10?

[me-no-dev]

so, I can not fix the error in IDF, but with the commit I linked above this has been fixed to not cause exception.
