Description
I am using example code from wifi provisioning library. I am setting #define CONFIG_IDF_TARGET_ESP32 1 in my .ino And trying to provision using BLE.
I am dumping the same code, once in esp32 dev kit and then in esp32-c3 dev module. In ESP32 Dev kit, the provisioning is successful without any errors. But in ESP32-C3 module, it prints this error in serial on connecting from esp ble provisioning app(both android and IOS).
E (7299) BT_GATT: gatts_write_attr_perm_check - GATT_INSUF_AUTHENTICATION
From Android app, despite this error, i am able to provision the device. But in the IOS it asks for the pairing and then it fails. I am not able to provision.
The same setup in esp32 devkit works perfectly fine.

Checked with the latest git. I am able to provision the esp32-c3 device via ios also. However, on serial we are still getting the same message during the process.
