Good news, I am looking forward to.

I can't get the logs for Xiamoi, it was my client who did the test.

Yes the SOC is different, but the Bluetooth chipset we don't know.

Interesting. From the logs, do you notice any difference between Xiaomi and Samsung in how/when they fail dfu?

The Xiaomi device appears to come with a different chipset, so I guess the controller is different as well. Anyway. We are going to order the Samsung tab to see if we can reproduce the issue here. It will probably take a few days for us to receive it.

Hello,

You seem to be experiencing the same issue discussed in this thread: https://devzone.nordicsemi.com/f/nordic-q-a/88202/dfu-error-unable-to-write-op-code-3-error-133/ that is still under investigation. I suspect it may be caused by some interoperability with this particular tablet/chipset and that we will need to get hold of the same tablet here to reproduce it on our side. I will discuss the issue with my colleague who had the other case and get back to you.

Best regards,

Vidar
