Secure DFU OTA for nRF52840 solution modules: Guide to create hex/zip file for implementation – #2(Application)

Posted on by 2 Comments

Following up-Part A: Bootloader (Click for article link)

We will be focusing on:

Part B: Application

in this article.

IC: nRF52840
DK: PCA10056 (for nRF52840)
SDK: 17.1.0
Softdevice: s140_nrf52_7.2.0_softdevice.hex
IDE: Keil C
PC: Win 10


Part B: Application

Path: nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_uart\pca10056\s140\arm5_no_packs

Before building Application code , some amendments need to be made regarding DFU-related settings and code inside Application:

Step 1.


1A. Add code in definition in C/C++ :
BL_SETTINGS_ACCESS_ONLY NRF_DFU_SVCI_ENABLED NRF_DFU_TRANSPORT_BLE=1
(Total 3 steps definitions need to be set up)


1B. Add “include path” in C/C++


1C. Add the .c files inside red frame in (Screenshots 1 & 2)
and the 2 groups of (nRF_DFU & nRF_SVC)(Screenshot 3) under Project(Screenshot 4)



1D. Add code into main.c file in Application (..\examples\ble_peripheral\ble_app_uart\main.c)
(Please refer to: main.c file at: ..\examples\ble_peripheral\ ble_app_buttonless_dfu)


1E. The code of file: sdk_config.h (..\examples\ble_peripheral\ble_app_uart\pca10056\s140\config\
sdk_config.h) inside Application needs to be modified.


1F. Adjust the IRAM1 value in Target after implementing DFU service:
Check on the IRAM1 Value of *p_app_ram_start to be modified from default: 0x20002AE8 0x3D518 to 0x20002AF8 0x3D508, as shown in the red frame in the bottom right corner.
In this case, the program should run successfully.


1G: Create a file of: nrf52840_xxaa.hex after building application code files.


Step 2. Create a bootloader setting file of nrf52840_bootloader_secure_settings.hex : (via DOS)

nrfutil settings generate –family NRF52840 –application nrf52840_xxaa.hex –application-version 3 — bootloader-version 2 –bl-settings-version 1 nrf52840_bootloader_secure_settings.hex –no-backup


※Stay tuned for #3 – Part C: Combining and merging built files in the next article,

scheduled release in next week(05/06/2024).

Raytac announces release of AN54H20 Series Module based on Nordic’s nRF54H20 chip solution

Posted on by Leave a comment

Raytac Corporation, a Nordic-recommended third-party module manufacturer based in Taiwan, today announces the upcoming release of the AN54H20 modules, which are built on the base of Nordic’s nRF54H20 SoC.

The AN54H20 module comes in a 9.8 x 13.8 x 1.8mm (0.37 by 0.53 by 0.07 inches) dimension factor and offers 3 versions of high-performance antennas, including ceramic chip antenna, PCB-mounted antenna, and uFL connector for external antenna. Output power is adjustable up to +10 dBm and data rate is adjustable up to 4Mbps to maximize RF performance.

Powered by multiple processors, AN54H20 modules provide the IoT field with access to a whole set of improved features, including 2MB flash memory/1MB RAM and bigger processing power for more complicated computations.  It also enhances protection against security threats, providing developers with protection while building technologically advanced IoT applications.

Hardware wise, AN54H20 inherits nRF54H20’s set of versatile, advanced, and low-power peripherals alongside DMA support, including high-speed USB, CAN-FD controller, 14-bit ADC, 2 x I3C and plenty more.  What’s more revolutionary is that AN54H20 brings power efficiency to a whole new level through accurately controlling currency consumptions under various modes, allowing smaller batteries to be implemented in the applications while increasing its life expectancy.

“We see the AN54H20 series as a potential market changer.  The compact size gives developers a seamless switch from the previous generation modules to AN54H20, and the remarkable power efficiency and characteristics AN54H20 brings will offer a magnificent effect to the inescapable hot trend of IoT and other various industries.” – Lyon Liu, President of Raytac Corporation.
