nRF Mesh App Cannot Interact with Devices after IV Index Update

jm_solar

We are finding an issue where after a network is running for a while we are unable to interact with devices beyond connecting to them via the nRF Mesh App. Specifically, we are trying to deprovision the devices. This is true across multiple devices - iOS and Android running the latest App/Play Store versions. The devices are one nrf5240 and multiple nrf52840 on the network.

The steps to get to where we are right now:

- Setup the network and save the json

- Wait a while (letting devices operate, come back later to change configuration)

- Import the json from that network

- Try to connect to the devices to deprovision

    - Able to see all devices

    - Unable to interact with them

Using the nrf Mesh Sniffer I am able to see that the IV Index of the network has been incremented to 1 in this time. I don't have any logs to prove this is the issue (please let me know what can be collected to help) but I am unsure what the other culprits could be for this issue that seems to be time based only.

I found this issue on Github from the library that seems to be what we are facing: https://github.com/NordicSemiconductor/Android-nRF-Mesh-Library/issues/537

However that issue is resolved and the fix seems to have been rolled out into the apps. So unless there is a regression I am unsure why we are seeing the same issue today on the latest versions.

Any direction on how to confirm this is the issue and resolve this would be appreciated.

Thanks

    Hi

    I talked to our nRF Mesh developer today, and they agree with you that you should get the IV index when returning. If you have a Mac OS device, you can use an app called Console (native on Mac), and select the connected iPhone, enable Debug and Info messages in the menu, and set a filter for 'subsystem = com.nordicsemi.nRFProvision' 

    That should give you some useful debug info. If you're not able to get anywhere from that, please upload that here and we can review the debug info on our end.

    Best regards,

    Simon

    Hi Simon,

    I don't have logs for you yet, are Android logs okay? We currently primarily are developing for android so that will be easier for us.

    I wanted to update that one of our engineers seems to have found a "work around" perhaps. It seems that if we create a new provisioner and operate as that provisioner instead we can interact with the devices and de-provision them. This new provisioner can also be shared between devices. Perhaps the new provisioner will also stop working next IV-Index update. Unfortunately these devices need to be updated so I don't think they will operate that long. But I will try to get an android log before they are taken down.

    I've attached a log from the Android app. In this session I did the following:

    1. Tried to get the TTL from the connected device (timed out)

    2. Tried to deprovision the connected device (timed out)

    3. Created a new provisioner and set the phone to use this new provisioner

    4. Again requested the TTL from the connected device which succeeded.

    I was also able to crack open one of our devices today to get logs (they were in sealed enclosures for environmental testing which restricted access). I found that the device was rejecting the messages as a replay attack - it seems the IV index update was a bit of a red herring. Apologies for spending your time on that.

    It seems like perhaps the best practice is that every device should be allocated its own address rather than having all the phone devices share an address? Or is there a good way to share the sequence number?

    Ah, I see! I didn't catch that you were sharing the sequence number/address of the provisioners. Doing that will effectively be replay attacking yourself. Each provisioner should be allocated its own unicast address. This approach avoids sequence number conflicts and ensures that each provisioner operates independently within the network.

    Glad we have it figured out then. Let me know if we can close this case or if you have any further follow-ups.

    Hi Simon,

    Thank you I think this is solved and can be closed
