Hi Abhijith,

By porting the authentication mechanism from the Peripheral LBS Sample, I was able to confirm that authentication is required before DFU in other samples as well.
I will try other authentication mechanisms as well.

Thank you for your support.

Kind regards,

Hello,

[quote user="a.da"]First, I must apologize. I was using the wrong sample as the base.

No worries

[quote user="a.da"]Part of this authentication logic is within the main.c of the Peripheral LBS Sample.[/quote]

Yes, that is true. If you look at the main.c file of the peripheral_lbs sample, you can see that CONFIG_BT_LBS_SECURITY_ENABLED is defined. This configuration changes the authentication mechanism when enabled. However, this authentication is only for the normal LBS connection. If you enable CONFIG_MCUMGR_TRANSPORT_BT_PERM_RW_AUTHEN, DFU will require authentication before allowing firmware updates.

For passkey display, auth_passkey_display() is used. Also, see the authentication callback.

Kind Regards,

Abhijith

Hi Abhijith, thanks for your reply.

Please allow me to confirm if my understanding is correct.

Part of this authentication logic is within the main.c of the Peripheral LBS Sample.
To enable authentication in other samples or custom projects, it is necessary to separately adapt and modify the logic from the Peripheral LBS Sample.

I mistakenly thought that simply enabling CONFIG_MCUMGR_TRANSPORT_BT_PERM_RW_AUTHEN would activate the authentication logic within the SDK.

Hello,

I tried that exercise just now, and it is working fine on my side. After selecting the swap type "Test and Confirm," you will receive a pairing and connection request, where you will be prompted to enter the passcode generated in the serial terminal. I am attaching a screenshot that I received while testing the exercise.

I used nrf5340dk and NCS v2.9.0

Do you have any logs showing any issue from the nRF device?

Kind Regards,

Abhijith
