communication in between application core and network core in nrf5340

[SRINI]

Hi ,

My environment:

• nrf5340 DK board
• nrf connect SDK v1.5.0
• segger Studio IDE

I would like to establish communication from application core to network core through send/receive messages . I am not sure how to proceed for this activity.

could you please provide me example codes for testing the communication through send/receive messages from application core to network core.

Thanks & Regards,

Srinivas.

Hi,

What kind of information do you plan to send/receive ?

If you build a Bluetooth sample for the nRF5340 application core, it will automatically build the Bluetooth: HCI RPMsg sample, which uses the RPMsg transport using the OpenAMP library to communicate between the Bluetooh Host(application core) and Bluetooth controller(network core).

Hi Sigurd,

we have a plan to send some set of bytes from application core to network core .

we shall execute some functionalities in network core depends on received bytes from application core.

I hope, I have answered to your question.

I request you , please provide me example codes for data communication between application core and network core.

It would be helpful for further implementation in my application.

Thanks & Regards,

Srinivas.

 The RPMsg Service sample Application demonstrates how to do this. See these links:
