first secure connection after DFU fails. SDK17 S113

Allen

Hello.

After performing a secure DFU download, the first attempt to open a secure NUS connection fails with an NRF_ERROR_INVALID_PARAM error. After resetting the device, all subsequent connections are successful. I have traced this to the call to BLE_GATS_EVT_WRITE handling in gatt_cache_manager.c. gscm_local_db_cache_update() fails in pdb_write_buf_store() because the peer_id is not tagged as allocated?

Below is a log. The first part is the connection attempt right after the DFU operation. The second part is the connection after reset which is successful.

    Hi,

    I do not have an explanation for this strange behaviour. There should not be any difference between the first and second time the application runs after reset, and it is odd that the peer manager does not find the bonding information in flash the first time but it suddenly reappears after a reset. Are you able to reproduce this on a DK? Can  you share the project so that I can have a look and test on my side?

    Yes, it is very strange.

    The PM library knows about the peer. pm_peer_id_get() returns the correct peer ID for the specified connection handle. My initial assumption was that this would fail and I would need to manually add the peer using pm_peer_new().

    The error isn't identified until a BLE_GATTS_EVT_WRITE event. The BLE event handler in gatt_cache_manager ultimately causes the error when updating the local DB.

    I should also note that this is on Android. It assumed that the bond used for the secure DFU is preserved and used when the new firmware loads.

    Yes the peer manager library knows about the peer and according to the log the connection is secured (which happens using the stored bondign information) also the first time, before the error happens.

     I see. So pdb_write_buf_store() returns NRF_ERROR_INVALID_PARAM (7) because the peer ID is not allocated, or so it seems. Is there a timing factor there? What happens if you delay the GATT write?

    Allen said:

    Yes, the bond is preserved provided you have configured the application and bootloader correctly (so that the bootloader is configured to stay away of the FDS pages). This does not seem to be the problem though: the link is secured, so the boning information is clearly present.

    Do you have any code that can reproduce this on the DK?

    Here is a log from a Windows DFU process. The main difference is that in Windows we delete the bonds on both sides after the DFU operation. (work around Windows bug) This works fine.

    Could the issue be passing the bond information back to the application from the bootloader when the DFU is complete?

    Another detail that I should point out is that this is a DFU upgrade of the entire chip.

    from SDK14, S132 v5.0 to SDK17, S113 v7.2.0

    Everything is different, including the format of the bootloader settings file.
