Pairing and bonding not functional in the peripheral accept list example

[bkaiwalyabosch]

Describe the bug

Hello, I tried to build and run the peripheral accept list example from zephyr\samples\bluetooth\peripheral_accept_list on the STM32 Nucleo WBA55CG, and do not get the pairing pop-up to pair and further bond with my smartphone Oneplus Nord (Android 13).

To Reproduce

• run samples\bluetooth\peripheral_accept_list example for the STM32 NUCLEO-WBA55CG
  west build -b nucleo_wba55cg
• try to connect using a smartphone using nRF Connect App
• perform a write operation '01' to the write_characteristic_uuid characteristic after connection is established

Expected behavior

Pairing pop-up is received on the smartphone immediately after the write is performed on the write_characteristic_uuid characteristics

Impact

• Pairing and bonding is unsuccessful which impacts implementation of security requirements in our project

Hi, I could get the pairing pop-up to enable 'Just works' pairing by adding a macro in the prj.conf file: CONFIG_BT_SMP_ALLOW_UNAUTH_OVERWRITE=y
