Hello,

Thanks for the update.

hci_ipc (previously named hci_rpmsg) is the name of the BT controller sample application that is programmed onto the network core, see Protocols and use cases.

HCI stands for Host controller interface:

And IPC stands for interprocessor Communication. The BT host on the application core use the IPC transport to communicate with the BT controller on the network core.

Hello,

Thanks for reply.

I took your advice and created a hci_ipc.conf file in the child_image folder and put CONFIG_BT_EXT_ADV=y in the conf file and the extended advertising worked. Great.

By the way, what are hci_ipc and hci_rpmsg abbreviations?

Hello,

Support for extended advertising must also be enabled in the BLE controller running on the network core. You can see how the peripheral_hr_coded sample enables extended advertising for the BLE controller child image here /nrf/samples/bluetooth/peripheral_hr_coded/child_image/hci_ipc.conf.

Permanent configuration changes to child images
