E (123456) wifi_init_default: netstack cb reg failed with 12308 (IDFGH-14107)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

In ESP-IDF 5.3.1 with ESP32.

After using
esp_wifi_set_mode(WIFI_MODE_STA);
to disable the AP, this error appears:

E (123456) wifi_init_default: netstack cb reg failed with 12308

What does this error mean? And how do I fix it?

[kriegste]

I do a

esp_wifi_set_protocol(ESP_IF_WIFI_AP, WIFI_PROTOCOL_11B | WIFI_PROTOCOL_11G | WIFI_PROTOCOL_11N | WIFI_PROTOCOL_LR);

just before changing the mode. This seems to be the cause of the error. How can I avoid this problem?

@kriegste
sorry for late reply ，could you please put the whole code which can reproduce the issue, this may help us to find the true reason correctly and quickly

ESP_ERR_WIFI_STOP_STATE: /* 12308 0x3014 Returned when WiFi is stopping */

[kriegste]

Try these two lines:

esp_wifi_set_protocol(ESP_IF_WIFI_AP, WIFI_PROTOCOL_11B | WIFI_PROTOCOL_11G | WIFI_PROTOCOL_11N | WIFI_PROTOCOL_11AX | WIFI_PROTOCOL_LR);
esp_wifi_set_mode(WIFI_MODE_STA);

You might ask why I do this.

esp_wifi_set_protocol() always enables/disables the LR protocol for both the STA and AP interface. This is a general problem in ESP-IDF.
When my app needs to open an access point, it has to disable the LR protocol. Otherwise the access point cannot be found by any phone or computer.
So when it closes the access point again (this is the code above) the LR protocol needs to be enabled again.

Of course, it would be best to finally solve the underlying root issue, which is this:
#9978

@kriegste
this err means the program is doing wifi stop, and we dont allow other apis to interrupt this action or doing wifi stop again.you should check your code about releated api which will do wifi stop

[kriegste]

You mean esp_wifi_stop()? There is not a single call to this API in my whole app.

[hansw123]

@kriegste
other apis may have wifi stop action such as change wifi mode, change config and so on.
may be you can post more detailed code for refer,thanks!

[kriegste]

I am working on a minimum code example. It is a bit harder than I thought.

[hansw123]

@kriegste could you offer your code which can reproduce the issue ， or we can not find the root cause

[kriegste]

I could narrow the problem down to the use of esp_wifi_internal_set_retry_counter() (I have very poor WiFi in one spot of the building and was experimenting with this function).
