KB: Getting Started with RSL15

RSL15 is an ultra−low power secure Arm® Cortex®−M33 processor−based Bluetooth Low Energy 5.2 wireless MCU. But what can it do? Thats entirely up to you and heres how you get started!

Step 1 - Request an RSL15 evaluation board from your onsemi sales representative and download the RSL15 SDK from www.onsemi.com/rsl15.

The SDK components are presented on the webpage in the following download table:


You will need to download the first three items (the others are optional):

  • RSL15 Documentation Package
  • onsemi IDE Installer (As of IDE version 4.1 the same onsemi Eclipse IDE can be used for both RSL10 and RSL15. You can install the new IDE without removing the previous version if you would like to maintain both environments.)
  • RSL15 Firmware Package

Unzip the documentation package and double click ‘RSL15_documentation.htm’. This opens the new html based on RSL15 documentation (note third party documentation is provided in pdf within the documentation package).

The documentation welcome screen looks like this:

The navigation panel on the left gives quick access to the major documentation topics. To get started, click on RSL15 Getting Started Guide. The Getting Started Guide walks you through using the RSL15 Central mobile app (Android, iOS), setting up your IDE of choice and compiling and downloading the ‘blinky’ application to the RSL15 EVB.


Once past the ‘getting started’ phase, the real fun begins… building your own application to meet your product’s needs. The RSL15 Developer’s Guide shows how to use the SDK sample code, the CMSIS-Pack and other general tools to build your application on top of the SDK sample code, plus some general diagnostics tips and more.


Depending where your application development takes you, you may refer to other topics such as:


Also remember third party documentation is not available in html but is provided in pdf within the documentation package.
