PeerManager error (error: 133)

[takashina hiroki]

I have a question about PeerManager.

SDK: 15.3.0
example: ble_app_multirole_lesc (I changed the source from the sample)
using device: EYSHJNZWZ (nRF52832)
connection device: Android (Bluetooth v5.0)

When trying to connect with LESC security level using PeerManager, the following error occurred.
Please tell me the cause.

<info> peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Bonding, error: 133
<warning> peer_manager_handler: Disconnecting conn_handle 0.

I know that this error means "BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP".
The connection partner supports pairing.
I confirmed that I could connect many times.
However, this error may occur.
Also, after this error occurs, the same error will occur no matter how many times you try to connect.
This error does not occur after reset.

Hi

You can make a .zip file of wherever you've stored the project in your SDK folder. For example, if your project is a modified version of the ble_app_multirole_lesc example, go to \..\nRF5_SDK_15.3.0_59ac345\examples\ble_central_and_peripheral\experimental  and copy the ble_app_multirole_lesc example into a .zip file. Additionally, please add any modified SDK files and tell me what IDE you've used, as well as add any specific details on how to build and reproduce this error.

Best regards,

Simon
