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 there

Okay, so the hardware works fine it seems. Are you able to reliably reproduce this or does it happen randomly?

Are you able to upload a sniffer trace, so that we can see what happens on air when this disconnect occurs? If not, you could upload your project here, so that I could take a look and try to find out what's wrong here on my end.

Best regards,

Simon

>> Okay, so the hardware works fine it seems. Are you able to reliably reproduce this or does it happen randomly?
This phenomenon occurs randomly.
It is difficult to reproduce reliably.

I don't own a sniffer.
Therefore, it cannot be confirmed by that method.

>> If not, you could upload your project here, so that I could take a look and try to find out what's wrong here on my end.
It is difficult to upload all the contents of a project.
You can upload some of them.
How do I upload a project?
Please tell me how.
