RE: NRF5340 Hello World APP+NET Core

Hi,

The most common architecture for using BLE on the nRF5340 is to run the Bluetooth controller on the network core, and the Bluetooth host on the application core along with the other application code. Please refer to the Split Controller and Host' section of the SDK documentation for more details.

[quote user=""]In future I'd be making application where the I2C part will be taken care by the app core and the BLE part would be taken care by the net core. For now I just want to have two images which prints hello world from their respective cores. Is there any sample application someone can share? There seems to be no application or sample where there is segregation between source code for both the cores.[/quote]

The Bluetooth controller (Bluetooth: HCI RPMsg) is automatically included as a child image when you build a Bluetooth example for the 'nrf5340dk_nrf5340_cpuapp' board using the SDK's support for Multi-image builds. You can browse the source code for this child-image by selecting it here in the UI:
