hi all,
I have added the dfu service in one of example of sdk_11 ble_scanner_hrs I followed all help available on this forum and made sucessfuly compiled code but it stopped advertising?
any help is appreciate I have attached my main file

I have attached the bootloder_util.c ,ble_dfu.c,dfu_app_handler.c and made changes according it.
I also changed ram setting in keil.
Thanks in advance
