nRF5340 Network core and application core communication

[geek]

Hi support team

I'm newbie to Nordic platform.
I'm currently working with nRF53 DK multicore on windows 10 using nRF connect SDK on VS Code.
I want to make use of the multicore of nRF53 to run BLE on the network core that handle BLE advertising and connection and sharing data up on request with the mobile app.
and on the application core i want to run a simple app that handle some sensor data collection and store in the internal flash and share these logs with mobile APP up on request. The challenge for me to share these data between the two cores and make the dual core run simultaneously.
How to get started with this challenge ?
I started with sample " multicore hello world " ,but it simply run the same app on both cores only without any data exchange.

Hi,

See example in Full Bluetooth LE stack.

Best regards,

Thank you for the guidance

I followed the sample
I have some questions

1- I only managed to flash the sample to the cpunet core and can't use multi image build ,but all i can see it this output “Starting nRF RPC bluetooth host” and the main function of sample is empty so i can't debug the code to understand its functionality how the sample is supposed to behave ? and how to perform the multi-image build ?

See example build:

"The recommended way of building the nRF RPC Host sample is to use the multi-image feature of the build system, building the sample with the same Bluetooth configuration as the application core sample. In this way, the sample is built automatically as a child image when the CONFIG_BT_RPC_STACK option is enabled."

I managed to build the Peripheral UART example using the provided command

" west build -b nrf5340dk_nrf5340_cpuapp -- -DCONFIG_BT_RPC_STACK=y "

but all i can see at the terminal as provided here and it can tells that the system reset and i can see any logs at the both cores also the BLE not advertising so i can discover it using the nRF connect mobile APP
