You shouldn't use documentation from older SDK. But anyway, you can either integrate the buttonless service to your application or add your application to the buttonless template.

Hi Mr Hung Bui,

I'm confused between the two options :

1. Add file DFU to ble_app_hrs according to link : https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk51.v9.0.0%2Fbledfu_appextending.html or https://developer.nordicsemi.com/nRF5_SDK/nRF51_SDK_v7.x.x/doc/7.0.1/s110/html/a00067.html

2. Add 1 service to ble_app_buttonless_dfu according to : http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v14.2.0%2Fble_sdk_app_buttonless_dfu.html&cp=4_0_0_4_2_2_6

Please , show me direction right .I use SDK 14.0 S132 Softdevice 5.0 , development kit NRF52832

Thank you.

Hi Giang,

Please study this example. It shows how to use DFU buttonless service to switch to DFU mode. Entering DFU is triggered by enter_bootloader() function. If you don't want to use DFU buttonless service but want to use UART service, you need to adapt your code base on the code of the DFU buttonless. On the bottomline, the ble_dfu_buttonless_bootloader_start_finalize() function does the part to write the flag to GPREGRET and reset the chip.
