esp_wifi_set_config password special characters

[jakobj]

We are struggling with special characters in the wifi sta password, everything works if we use a password with without special characters.

Code: Select all

    ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA) );
    ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_STA, &wifi_config) );
    ESP_ERROR_CHECK(esp_wifi_start() );

If

wifi_config.sta.password

is set to "password" or any other password without special characters, it works.

But if we set

wifi_config.sta.password

to example "pass&word" it fails.

And we did remember to change to AP's password accordingly.

So how do we use special characters ?

There's nothing special about an ampersand; esp-idf should simply use that. How do you set the password?

[jakobj]

Yes, I don't understand either.

We set it as follows, and it works for all other tested password without "special" characters.

Code: Select all

strncpy((char*)wifi_config.sta.password,"pass&word", PW_MAX_LENGHT);

And obviously PW_MAX_LENGHT is set to 10 or higher?

[jakobj]

yes, 64.
