No, you need to make that directory yourself.

in central project child_image/rpc_host.conf exist. but peripheral project do not have child_image directory and rpc_host.conf.

Hi,

Are you sure? If you are building for the application core(?) you will automatically get the hci_rpmsg as a child image for the network core. This is the Bluetooth controller, and without it, nothing related to Bluetooth or using the radio will work.

thanks, Einar i have a question for peripheral project.

peripheral project do not have hci_rpmsg by default.

if i add hci_rpmsg, how bind it to project?

Hi,

Do you use a nRF5340 DK as both a central and peripheral? If so, you need to configure both the application on the app core and the hci_rpmsg on the net core to support data length extension. From what I can see you have not doen this for the peripheral code. Other than that, the configurations you use seems good. You can refer to the configuration under 12. Configure the application to enable data length extension in Exercise 2 in the Bluetooth fundamentals course on the DevAcademy for more details (note that you need to click on "nRF5340 DK" to see the configurations relevant for that).

hello karl

this is my applications.

some codes and configs added, because my project is developing.

Hello,

From your console output it seems as though you manage to perform the MTU size update procedure successfully at least, but the logs indeed indicate that it has not been updated to the requested values.

Could you show more of your application? Is the code you have provided here the only additions/modifications you've made to the default Central/peripheral UART example?

Best regards,
Karl
