[mike zt]

I use the software S110 v8.00,and the NRF51822QFAA chip. now ,I need add DFU Service support to an application. I find the ble_peripheral\ble_app_hrs\pca10028\s110_with_dfu project. I have some question：

1.I only program s110 v8.00 hex and the hrs hex file 2 files to nrf51822 chip,then the chip hrs with DFU funciont? is right?

2.I wiil program s110 v8.00 hex ,the hrs hex file,and the dual_bank_ble_s110 hex ,3 files to the nrf51822,then the chip have hrs with DFU function? is right?

1. No, you need flash the S110 Dual Bank Bootloader together with the S110 SoftDevice and Application (ble_app_hrs/pca100028/S110_with_dfu) for DFU to work.
2. Yes.

I would take a look at this page on our InfoCenter, it explains how to add the DFU service to an application.

There are only serial single bank bootloaders, i.e. firmware update using the serial interface and not Over-the-Air(OTA). You can convert a Dual Bank Bootloader project to a Single Bank Bootloader by switching dfu_dual_bank.c with dfu_single_bank.c. Please see the attachment DualToSingleBank in my answer
