General issue report

Hello, I just updated my project to ESP-IDF Release v5.4.
Before the update I was using the Release v5.1.5 version for ESP-IDF Release v5.4 where I had pairing with a BT device with ESP_BT_PIN_TYPE_FIXED

# CONFIG_BT_SPP_ENABLED is not defined
# CONFIG_BT_SSP_ENABLED is not defined

in sdkconfig.esp32 and everything works fine,
Now that I've updated, when pairing a device, the pin is no longer asked for.

After comparing the sdkconfig. esp32 of the new idf with the old one, I discovered that the CONFIG_BT_SSP_ENABLED setting
It's not in the new one.

I did a search at ESP-IDF Programming Guidev5.1.5 by this config and it exists, search in ESP-IDF Programming Guide v5.4 he doesn't exist

Is there any reason why this setting disappeared?

Hi @tv4you2016,

Thanks for your reporting. From release/v5.2, pairing mode can be configured at runtime. API esp_bluedroid_init has been updated with esp_bluedroid_init_with_cfg. You can use legacy pairing by calling esp_bluedroid_init_with_cfg with the parameter ssp_en setting to false. We will add some instruction in migration guide about this change later.
