LE Secure BLE Connection

[Niels-Be]

Zephyr by default (since v2.2.0) requires authenticated connections to access mcumgrs GATT service.
However I have not found a way to instruct mcumgr-cli to pair the device before use.
Even if I pair my host (running bluez 4.48) to the device before using mcumgr I still get:

Error: Insufficient authentication

Is there any support for authenticated connection / is it planed?

Are you using it with Zephyr?

If so, you could try to set CONFIG_MCUMGR_SMP_BT_AUTHEN=n in your service.
I was told to do this to remove the BLE authentication requirement from the mcumgr SMP characteristic.

How ever it was for another issue, so I don't know if it helps.

Yes disabling security works.
However this is not an option for our use case and it is not what I was asking for.

I have hit the same problem, seems that mcumgr reset the connection and all of the pairing information is lost

Just discover that you can use the DFU upgrade utility of the android/ios nrf Connect app, and upload images to zephyr mcuboot, but is slow

Hi,

I have the same problem.
If using nordic App Device Manager, everything works. I am able to pair device with the phone and then I am able to send all the commands using the App.
If using mcumgr-cli, I can pair the device using bluetoothctl and every command using mcumgr-cli have the same error:

Error: insufficient authentication

Do you know If mcumgr-cli supports authenticated connections?

Thanks
