DFU fails with "Cannot read property 'instanceId' of undefined"

[kobyatom]

running DFU example from <SDK 15.3>\examples\dfu\secure_dfu_test_images\ble\nrf52840, and attempting a DFU update of:

sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex

to

hrs_application_s140.zip.

The DFU is performed on the nRF52840 DK, using this procedure:

1. I burn the .hex image via the J-Link drive on a Windows PC, by copying it there.
2. I connect to the device via nRF-Connect on the Windows PC, and start the DFU process, selecting the .zip image.

Mostly, the DFU is successful, and Nordic_HRM becomes the device' name.

Sometimes, the DFU fails with "Cannot read property 'instanceId' of undefined".

I have the failure logs, of both the RTT log of the device

After such a failure message, I can try to the DFU again, and sometimes it will succeed.

[gaminn]

I have exactly same issue. Sometimes it fails with this error. It seems it only happens where my device runs my application and is restarted to DFU mode using nrf connect on Win10. I didn't see this error when my device is already in dfu mode. What this error means? I also noticed that after some time nrf connect became very slow in updating firmware (0.35 kB/s). After restarting nrf connect the speed normalized around 1.5 kB/s.

gaminn:

Are you running the tutorial that I linked in my previous reply, or did you modify the bootloader? Are you using bonding, either in your application or your bootloader?

[gaminn]

I modified the bootloader to support AES encryption of the firmware.

My device uses bonding, but bonds sharing between app and bootloader is not enabled.

gaminn:

Please create a new ticket where you describe what changes you did, and what your symptoms are. It doesn't look like this is "exactly the same issue". It is related to DFU, but that is about it

Hi There,

is there an update for this issue? Thanks!
