Hi,
I'm checking whether SDK 13.0.0 secure bootloader dfu can proceed correctly with iOS DFU library if the process is interrupted because smartphone application is restarted, or ble connection is lost, and so on.
I have tried artificial interruption many times, and for most of the times it has succeeded. But sometimes it failed. When it fails, it gets "Write request too long" error and return NRF_DFU_RES_CODE_INVALID_PARAMETER. Even though I reset and restart CPU, it still gets same error.
And after it gets the error many times, it seems to process the data transportation. However, it transports the same object repeatedly.
Is this known bug? If so, how can I fix it? Is this FW bug or iOS library bug in the first place?
If not, I think I can resolve this issue by resetting the object offset, or delete the bank, on restart CPU. How can I reset the object offset?
I attached the log file. secure_bootloader_dfu_error_log.txt
Thank you.
