I modified the "ble_app_uart" project on "nRF5_SDK_15.2.0_9412b96".
I added the "peer manager" function.
The first pairing works perfectly.
After performing the NoPairing function, it is no longer possible to perform a second pairing.
The message "peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Bonding, error: 133" appears on the terminal.
To be able to perform a pairing again, the startup must press an EVAL button to execute the "delete_bonds()" function.
How can I solve this problem ?
See the terminal report below.
Thanks.
