Link Loss DFU SDK13

[Albin]

Hello i'm currently working on the central part of the DFU i succeded to make it work and now i'm working on the link loss part.

I used This to make the DFU work but it doesn't indicate what process has to be made to recover from a link loss.

Do you know what i have to do ? I'm sure there is a better way that just sending the image again form the begining.

Thanks for the help

Hello,

The link that you sent does describe what you can do if there is a link loss:

" If the transfer of a data object fails (for example, because of a power loss), the transfer can be continued instead of restarted."

Please check the section: Transfer of a firmware image

I believe you can use the offset and CRC to check what the last successful object. 

 

Best regards,

Edvin

I don't exacly get it, when i'm reconnecting to the device and the last data object selected hasn't totally been sent do i have to recreate the same object and send it all or do i only have to send what's missing ?
