Step 1. Execute the combine batch file in bootloader (nrf52840_bootloader_setting_merge.bat) and generate file of nrf52840_bootloader_secure_combin_settings.hex :

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin
set BS= nrf52840_bootloader_secure_settings.hex
set BL= nrf52840_xxaa_s140.hex
set BSBLCombind= nrf52840_bootloader_secure_combin_settings.hex
set path=%nrfDir%;%path%
pause
echo -----------merge image file-------------------
mergehex.exe -m %BS% %BL% -o %BSBLCombind%
pause

---

Step 2. Create a Final.hex file by 3-in-1 batch file(nrf52840_3in1_merge.bat)
※Note : This hex file is created for the production line to pre-load firmware into modules prior to shipment.

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Users\user\Desktop\Nordic BLE\nRF5_merge tools\nRF52 bin
set SD= s140_nrf52_7.2.0_softdevice.hex
set BLT= nrf52840_bootloader_secure_combin_settings.hex
set APP= nrf52840_xxaa.hex
set SD_BLT=SD_BLT.hex
set Finalfile=Final.hex
set path=%nrfDir%;%path%
pause
echo -----------merge image file-------------------
mergehex.exe -m %SD% %BLT% -o %SD_BLT%
pause
mergehex.exe -m %SD_BLT% %APP% -o %Finalfile%
pause

---

Step 3. Create a DFU(OTA).zip file of nrf52840_xxaa.zip
※Note : This zip file is created for end device DFU(OTA) implementation.

nrfutil pkg generate --hw-version 52 --sd-req 0x100 --application-version 0xFF --application
nrf52840_xxaa.hex --key-file private.pem nrf52840_xxaa.zip

The DFU OTA zip file: nrf52840_xxaa.zip will be derived.

---

※Note :
The "0x100" appeared in the above DOS code(in red font) is the FWID(Firmware ID) for s140_nrf52_7.2.0_softdevice.hex;
FWID can be found from the soft device documents on the Nordic website.

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

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,

Why Does Raytac AT-Command Module Not Require An End Code Mechanism?

Developers may be familiar with using ‘\n’ (hex 0x0A) or ‘\r’ (hex 0x0D) as end codes to determine the end of a data packet when writing programs. In the original Nordic SDK example code, ble_app_uart, is to consider the reception of 244 bytes or the presence of ‘\n’ (hex 0x0A) or ‘\r’ (hex 0x0D) as end code as the end of a data packet. The program then sends this received data via BLE to APP.

Developers encountering Raytac AT-Command module for the first time may find it very unfamiliar and be puzzled by the absence of 0x0A or 0x0D end code. You may raise questions about how to receive complete information without relying on these end code? Therefore, we’ll provide explanations for common use cases of AT-Command in both connected and disconnected scenarios:


In the connected condition –
Raytac’s AT-Command module operates in Pass-Through mode. For instance, when the APP sends 0x41 0x42 0x43 (3 bytes) through the module to the MCU, the MCU will receive only 0x41 0x42 0x43 (3 bytes). When APP sends these 3 bytes, there is no need to include the 0x0D end code or 0x0A end code at the end. The same approach applies when the direction of transmission is reversed (i.e., when the MCU sends to the module and then to the APP).

Here, it’s crucial to note that there is a specific consideration for the “Data Interval” (DI) setting between transmitting one data packet and the next. Failure to configure the DI appropriately may result in packet loss and lead to Bluetooth disconnection shortly after data transmission. The recommended DI values vary at different Baud rates, and you can refer to the AT-Command specification for suggested DI values.
As an example, consider Raytac AT-Command module in the scenario of “Mobile App -> Module (MDBT42V-AT) -> MCU,” with a Baud rate of 9600, no flow control, and a data length of 244 bytes. In this case, the DI value for transmitting data must be at least 250ms to prevent packet loss.

In the unconnected condition –
Providing explanations to the Bluetooth module by sending AT commands from the MCU (or Console) is illustrated below. There is no need for 0D or 0A end codes at the end.
