DFU failed in 2nd attempt

[Nomi]

i have successfully uploaded my custom made file to my nrf51422 sdk v8.0 and softdevice s110 using DFU/bootloader. but when i try to upload my file 2nd time i got an error which says. Error on discovering service Message:required DFU service not available on peripheral. i have created my zip file using nrfutil.exe from master control panel. and for DFU i am using an example project dfu_dual_bank_ble_s110_pca10028.

i used the following steps. nrf51422 sdk v8.0 and softdevice s110 on pca10028 the steps i used to do dfu are as 1)programed soft device s110_nrf51_8.0.0 using nrfgo studio 2)programed dfu_dual_bank_ble_s110_pca10028 an example from keil pack. 3)compiled my custom made application which is attached here DFU in password.zip 4)created zip file using nrfutil.exe using hex file generated by uisng this command nrf.exe dfu genpkg app.zip --application nrf51822_xxac.hex --application-version 0xffff --dev-revision 0xffff --dev-type 0xffff --sd-req 0x0064 5)uploaded zip file to my ios app nrftoolbox 6)opened DFU from nrftoolbox and uploded my application whick worked perfectly the problem is when i try to upload my applicatons 2nd version it does not connect to dfu and there comes an error Error on discovering service Message:required DFU service not available on peripheral reference link infocenter.nordicsemi.com/index.jsp

@Nomi: next time if you want to update a file, please edit your question and add the file there. Don't post your comment to my answer as an answer. You should post it as a comment.

I had a look at your code. You has copied and added the DFU service into your account.

But when copying you also copied the macro operator : "#ifdef BLE_DFU_APP_SUPPORT". If you don't define "BLE_DFU_APP_SUPPORT" or don't add it into the "Define" text box in Project setting-> C/C++ tab. Then the compiler will ignore that code. And it will result that you don't have DFU service in your application.

Please have a look at the project setting in the \examples\ble_peripheral\ble_app_hrs\pca10028\s110_with_dfu 's project setting.

I suggest you to use Master Control Panel tool either on PC or on Android or Lightblue app on iOS to check what in your ATT table.

Now DFU is working fine but my uart does not accept my static passkey it just disconnects.

@Nomi: Could you capture a sniffer trace ? You can try to rollback to the version that it still worked for you and check what would go wrong. FYI we have a static passkey example here.
