1. Hardware Environment Setup
The required equipments are as follows:

1 x Nordic nRF54L15-DK: PCA10156(1.0.0)
1 x AN54LV-DB-15 (Raytac nRF54L15 module Development Board)
1 x IDC Ribbon Cable
2 x USB Type-C Connection Cables

* Reminder: The “Nordic nRF54L15-DK" and “Raytac AN54LV-DB-15 Development Board" must be used together to proceed with application development and flashing firmware into the Raytac AN54LV-DB-15 development board.

Setup Steps:
Step 1: Connect the J-Link on the Nordic DK with the AN54LV-DB-15 using the IDC ribbon cable.

Make sure to match the red side of the IDC ribbon cable with **“1″** printed on the AN54LV-DB-15’s J-Link socket.

Step 2: Use the Type-C USB cables to supply power to both the nRF54L15-DK and the AN54LV-DB-15.

The outcome should be same as the picture above.

2. Software Development Kit Resources and Environment Setup
Software Tool kits & Download Links:
Download nRF Connect for Desktop: Download nRF Connect For Desktop (Please Click Me)
Download nRF Command Line Tools: Download nRF Command Line Tools (Please Click Me)
Download Visual Studio Code(VS Code): Download nRF Command Line Tools (Please Click Me)

Setup Steps:
Step 1: Download the latest version of nRF Connect for Desktop. Choose the Windows 64-bit – version 5.3.1 installer (nrfconnect-setup-5.3.1-x64.exe). Once finished, you will see " nRF Connect for Desktop" on your PC.

Step 2: Download the latest version of nRF Command Line Tools. Choose the Windows X86 64 – version 10.24.2 installer (nrf-command-line-tools-10.24.2-x64.exe)

* Reminder: During the installation of the above two programs, a window may pop up prompting that SEGGER J-LINK needs to be installed or updated concurrently.

If you’re initiating Segger Embedded Studio (SES) application, please check the guideline here(Click me)

Step 3: Download the latest version of Visual Studio Code (VS Code). Choose Windows VSCodeUserSetup-x64 version 1.122 (VSCodeUserSetup-x64-1.122.1.exe). Once complete, you will see “Visual Studio Code" on your PC.

Step 4: After installation is complete, you can verify the installed packages in your PC’s Control Panel under “Programs and Features":

3. Software/Firmware Application Development
You can develop application programs within the VS Code IDE development environment.
Below steps are how to install and select your target SDK version (nRF Connect SDK v3.3.0 in this article):

Step 1: Launch “VS Code"-> Select “nRF Connect" icon/extension on the side menu.

Click “Manage SDKs" and then select “Install SDK".

Step 2: Select “nRF Connect SDK".

Step 3: You will see several available versions of nRF Connect SDK vx.x.x. It is highly recommended to choose and install NCS v3.3.0 or later. In this guide, we select nRF Connect SDK(NCS) v3.3.0.

Step 4: Before starting the download for (NCS)v3.3.0, confirm your preferred target installation pathway.
By default, it is configured to c:\ncs\v3.3.0. Press ‘Enter’ to confirm.

Step 5: Once the nRF Connect SDK v3.3.0 environment setup finishes successfully, open the Bluetooth sample folder and select the “peripheral_uart" application template, then click “Open".

Step 6: In the “nRF Connect" layout, go to “Applications" –> “Add build configuration".

Under “Board target", look up and select “nrf54l15dk/nrf54l15/cpuapp" –> “Generate and Build".

* Note: You can also choose the board name “raytac_an54lv_db_15/nrf54l15/cpuapp” for subsequent building and development.

After completing the configuration, you will see “Build complete".

Step 7: Compilation completed. Once completed, a binary file named “zephyr.hex" will be generated in your “build" directory.

Step 8: Under the “ACTIONS" interface, you can switch between Build, Debug, and Flash functionalities dynamically.

Build

Debug

Flash

Step 9: CRITICAL BEFORE FLASHING/DEBUGGING: You have to change the VDD voltage configuration on the nRF54L15-DK board to 3.3V.
To do this: Launch “nRF Connect for Desktop" -> choose “Board Configurator" -> click “Open"

Change the VDD target selection value to “3.3V" -> click “Write config".

4. Flashing / Programming
The nRF Connect SDK (NCS) natively supports direct programming.
You can utilize the “Programmer" application tool to flash the compiled zephyr.hex binary file onto the target chip.
The exact procedure is detailed below:

Step 1: Open “nRF Connect for Desktop" -> select “Programmer" and click “Open".

Click “Select Device" and choose “nRF54L15DK".

Click “Add file".

Step 2: Select your compiled target “.hex" file.

Click “Erase & write" to initiate the programming/flashing process.

While flashing, a progress diagonal pattern will display on the right-hand panel.

When the LOG shows a “completed" status text, it means that the programming/flashing is successfully done.

Step 3: After the flash operation completes, you can download the “nRF Connect for Mobile" app to scan and verify that the Raytac AN54LV-DB-15 development board is advertising normally.

Software Kits Resource & Preparation
Download nRF Connect For Desktop (Please Click Me)
Download nRF Command Line Tools (Please Click Me)

Preparation
1. Prepared with the latest version of nRF Connect for Desktop and Select version Windows 64-bit – 5.1.0
2. Prepared with the latest version of nRF Command Line Tools and Select version Windows x86 64-10.24.2
**Note: SEGGER J-LINK Upgrade message might pop up while you’re doing above download.

If you’re initiating Segger Embedded Studio (SES) application, please check the guideline here(Click me)

3. Locate all the necessary kits for programming in PC (Check Software/Application list)

Get started with building your program

Intro: The development tool of nRF Connect SDK(NCS) equipped with free VS (Visual Studio) Code IDE for firmware compile and programming.
Note: it is highly recommended to apply NCS 2.8.0 for advanced features of nRF54L15.

Step 1 —- Activate your “nRF Connect for Desktop” >> “Toolchain Manager” >> “Open” >> “Install”

Step 2 —- You will find multiple options of NCS V x.x.x in the tool, we’re using NCS v2.8.0 as example to run sample code of nRF54L15.

Step 3 —- Make sure the NCS v2.8.0 is installed at same directory with compiling system. (the root of Open VS Code) (This is using C:\ncs as example.)

In case to organize the files, do “Select directory’” and “Confirm”.

Step 4 —- After nRF Connect SDK v2.8.0 Download ready , go “Open VS Code”.

Step 5 —- Go “Open Existing Application” , and activate example code: Bluetooth > peripheral_uart

Step 6 —- Moving to program build & compiling by selecting dev kit: nrf54l15dk/nrf54l15/cpuapp

Step 7 —- You will get a .hex file after the above programming compiling process.

Step 8 —- Functions are available for during the code compiling process under “ACTIONS” in VS Code IDE
<< Build >>

<< Debug >>

<< Flash >>

Firmware Programming
It is feasible to do the firmware programming using nRFConnect SDK (NCS) tool.
Developer may use “Programmer” to do the firmware flashing with the candidate .hex file.

Step 1 —- Execute nRF Connect for Desktop >> Programmer >> Open

“Select Device”

Select ”nRF54L15 DK”

“Add File”

Step 2 —- Select the candidate .hex file

Select “Erase & Write”

It indicates the programming process is on the way↓

The firmware programming process is done after seeing “Completed” in system Log field.

Step 3 —- Use the mobile App to make sure the Bluetooth broadcasting is functioning after the firmware flashing process is successfully done to the module.

D. Channel Sounding Preview

What is Channel Sounding? —- Advance the “Find My” feature into next level accuracy
Have you ever concerned about the distance accuracy when you’re using RSSI to get the distance between devices and to evaluate the transmission distance with legacy Bluetooth module?
Nordic NRF54 solution has taken us into next level with Channel Sounding feature that achieves the “centimeter-level” distance accuracy. Early implement achieves 10-20cm in the record.

How does Bluetooth Channel Sounding work?
Bluetooth Channel Sounding implemented with Phased-Based Ranging (PBR) & Round-trip time (RTT)(the concept idea of TOF time of flight) algorithm to achieve a higher precision of measuring distance between 2 devices.

Phased-Based Ranging (PBR):
Signal has been sent between initiator and reflector with multiple frequency to increase measuring accuracy.

Round-trip time (RTT): It’s the concept of utilizing TOA (Time of arrival). Using TOD(Time of departure) & TOA to measure the timing during the packet transmission between devices.

Potential applications:
Personal item finding
Secure access control
Smart lock system
Digital Key
Asset Tracking
