When built for a board target with the */ns variant, the sample is configured to compile and run as a non-secure application with Cortex-M Security Extensions enabled. Therefore, it automatically includes Trusted Firmware-M that prepares the required peripherals and secure services to be available for the application.

For testing this sample, you need to have the nRF Connect for Mobile app installed on your smartphone or tablet.

Overview

The sample implements two advertising sets:

  • Non-connectable advertising with the URI to the https://www.nordicsemi.com website in the advertising data. It shows the Bluetooth Broadcaster role (Beacon) functionality.

  • Connectable advertising with the 16-bit UUID of the Device Information GATT Service in the advertising data. It shows the Bluetooth Peripheral role functionality.

When you start the sample, it creates two advertising sets. Use your scanner device to observe the two advertisers:

  • Nordic Beacon that you can use to open the nRF Beacon website.

  • Nordic multi adv sets that you can use to establish a connection with the device.

Use your central device to establish the connection with this sample. When connected, the non-connectable advertiser is still shown on your scanner device. After disconnection, the connectable advertising starts again.

User interface

LED 1:

Blinks with a period of two seconds with the duty cycle set to 50% when the main loop is running and the device is advertising.

LED 2:

Lit when the development kit is connected.

Building and running

This sample can be found under samples/bluetooth/multiple_adv_sets in the nRF Connect SDK folder structure.

When built as firmware image for a board target with the */ns variant, the sample has Cortex-M Security Extensions (CMSE) enabled and separates the firmware between Non-Secure Processing Environment (NSPE) and Secure Processing Environment (SPE). Because of this, it automatically includes the Trusted Firmware-M (TF-M). To read more about CMSE, see Processing environments.

To build the sample, follow the instructions in Building an application for your preferred building environment. See also Programming an application for programming steps and Testing and optimization for general information about testing and debugging in the nRF Connect SDK.

Note

When building repository applications in the SDK repositories, building with sysbuild is enabled by default. If you work with out-of-tree freestanding applications, you need to manually pass the --sysbuild parameter to every build command or configure west to always use it.

Note

When using the nRF54H20 DK Engineering B (from v0.8.0 to 0.8.2), you must build samples and applications using the board revision 0.8.0 with the <board>@<revision> syntax. For example, nrf54h20dk@0.8.0/nrf54h20/cpuapp when building for the application core, or nrf54h20dk@0.8.0/nrf54h20/cpurad when building for the radio core.

Testing

After programming the sample to your dongle or development kit, test it by performing the following steps:

  1. Connect to the kit that runs this sample with a terminal emulator (for example, nRF Connect Serial Terminal). See Testing and optimization for the required settings and steps.

  2. Reset the kit.

  3. Start the nRF Connect for Mobile application on your smartphone or tablet.

    The device is advertising as Nordic multi adv sets and Nordic Beacon.

  4. Select the connectable variant and connect to the device from the application.

  5. In the SCANNER tab check if Nordic Beacon is still advertising.

    You can use it to open the Nordic website.

  6. Disconnect from the device.

  7. In the SCANNER tab, check again if there is an advertiser with the name Nordic multi adv sets.
