Could you please elaborate how to "disconnect the link and change the services?" I don't see any api supporting that.

I also use nordic DFU to do OTA service with android phone,but I found that some device can't update device's version some time? You met this kind of problem?

You can disconnect the link and change the services available and then reconnect. Would recommend you to implement a way for you to notify the central that you have changed the services and that it should do a new service discovery. This is to prevent the central from trying to access characteristics and services that aren't there anymore or have changed.

Alternatively you make sure that the services and characteristics related to you DFU operation is placed in the top of the attribute table after the GAP and GATT services. Then your DFU services will always have the same handles for your central to access.

You can do it if you disable softdevice and then reinit all anew with the necessary corrections.
