RE: Unable to continue image upload via SMP if device disconnects/restarts

Thank you for the quick answer.

I got the Info that I have to use the sha256 from the TLV from the source that you've linked.
The picture that you've linked is from the nrf connect documentation.

Though like you've said, it doesn't matter as there is no way to continue the upload.

Hi,

It cannot be corrected, so you need to upload the file again. Also, that is wrong, the sha you sent with the first packet is the sha256 of the file, not from the TLV. not that it really matters what you said, it's just used to continue uploading if you continue uploading the same file again. See https://docs.zephyrproject.org/latest/services/device_mgmt/smp_groups/smp_group_1.html
