Hi @TM33 ,
Thanks for contacting NXP support.
NXP provides a rich set of sample projects to help with BLE development. If you want to send and receive data over Bluetooth using QN9090-DK006, we believe that Wireless UART is a better DEMO for your requirements.
The application is built to work with another supported platform running the same example or with the Wireless UART from the IoT Toolbox application. With this sample project, you can try to implement data transfer between two QN9090 boards or one board and mobile app.
For more detailed implementation and usage instructions, as well as for other examples in the SDK, please refer to this document: Bluetooth Low Energy Demo Applications User's Guide.pdf , which located at this path: SDK_Root_Path\docs\wireless\Bluetooth\Bluetooth Low Energy Demo Applications User's Guide.pdf
Hope you are doing well!
Best regards,
Gavin
