Thanks to me and for fixing the problem, since the packet specifies 0xc0 as the end string, it is escaped to 0xdb and 0xdc

Hi,

I am not familiar with this output. Is this from a system you have developed? If you need input from me, please elaborate in mor detail on the details of what you are doing.

This is the transmission log, the error appears on line 158, I do not care about the error and the transmission is complete and can be used normally

I used the 1.7.0sdk, before the failure of several packages are normal, to the 12th package (4096) will report an error, if you ignore the error and continue to transfer can also work

Hi,

Can you elaborate on which SDK you use, how you perform DFU and show in more detail how thigns fail (full logs, etc)?
