DFU fails with "Android DFU library" for version > 1.11.1

Verification

• I searched for similar bug reports (including closed issues) and found none was relevant.

What happened?

Firmware update failed with error message: "Disconnected from GATT server"

What should happen instead?

Firmware should be updated

Reproduction steps

Create a flutter app
Install dependency:
nordic_dfu: 6.0.1

Add code for DFU with this library.
Build the flutter application

Try updating the infinitime image with the new built firmware.
The firmware update fails with error message:

Disconnected from GATT server

The android-dfu-library version used in the project is: 2.3.0.
The latest working stable version of android-dfu-library for updating the firmware is 1.11.1.

For same chip with this flutter application (with newer android-dfu-library version), DFU works for firmwares other than Infinitime.

No response

No repository file or test is named. Start by reproducing the failure with nordic_dfu 6.0.1 and android-dfu-library 2.3.0, then compare it with the working 1.11.1 setup using the supplied GATT and DFU logs. Done means identifying the compatibility cause and verifying a firmware update with the newer library.
