Hello,

Thank you for the logs. They are helpful. I can see that your device does not send any notifications when needed.
First, the phone sends a Read Mcu Params request at time 10:27:17/669-677. The request is explained here.

The timeout is set to 1 second, but during that time there's no response. The device should reply with McuParam response or with an error, but nothing is received. The timeout is ignored.

Then the phone starts DFU and the first thing being done is checking that's on the device (validation step) by sending Image Read State request.

Again, the device does not reply with anything. There's no notification in the log. As a result, the phone disconnects.

And here's when I'm not 100% about. The disconnection happens less than 2.5 seconds after the first request. In my option the timeout for the Image Read State command is 5 seconds. There are other requests with 2.5 second, but they aren't called yet. So I don't know why the phone:

1. disconnects
2. does it so quickly

Anyway, the target device should send notifications and it doesn't. I would start debugging in this direction.

Also, you may use nRF Connect Device Manager app instead of nRF Connect. It has slightly newer version of the library and also produces logs to nRF Logger, if needed. (You need to install nRF Logger from Play Store, there's no log pane in nRF Connect Device Manager app).

I would like to know if you have RTT logging working at all. Are you receiving any logs before, during, or after the DFU?

From the project configuration you provided, I see that you already have logging over RTT enabled. Are you receiving any logs over RTT?

Hello,

The log from the phone indicates that the connection is being dropped, but not why. Can you get debug logs from the board? This log may provide us with more clues. Also, with regards to the custom, does it have the same QSPI flash IC and pinout as the DK?

Best regards,

Vidar
