So I tried putting together some output that will show what I do, and not be over complicated. Difficult as lots of commands flow for the update process.

What I can do is send you the file (C#) that I use to preform the update process. The code is pretty self explanatory.

Do you Have an email address I can send it to?

Hi I am using SDK17

When I say slightly different timing, I mean that there are internal timing differences between the nordic app and my app. Same command, but the delays between commands are different.

I can provide you with my own log as generated by the ble app I wrote. Not sure what they will show, but I maybe I am missing a packet.

Will generate some nicer output and attach it.

Hi Riaan,

What version of the SDK you are using?

[quote user=""]I did a comparison on the serial port. same commands, slightly different timing.[/quote]

Could you elaborate more about the "slightly different timing"?

Is it possible to provide the debug log when it fails to update the new firmware?
