Hi,

For the network-core, you can build the rpc_host sample, without building the client. But for the application core, you need to set CONFIG_BT_RPC_STACK, and it will automatically build rpc_host as a child image.

What you have done is reprogramming both the APP and NET cores with one command. west flash also falls back to nrfjprog.

Please tell me whether it's possible to:

compile full BT stack + host to NET core only (no multi image!) with RPC enabled;
- burn to NET core only;
compile RPC client and beacon example to APP core only (no multi image!);
- burn to APP core only;

Later we want to substitute the "beacon example" with out custom RPC solution, therefore we need a "persistent" full BT stack on the NET core accessible by RPC on the APP core.

Hi,

I can't get it why it wants to write to NET core instead of the APP core.

Works fine here when I use nRF Connect for VS Code, using the flash action:https://nrfconnect.github.io/vscode-nrf-connect/connect/ui.html#actions-view

in the log I have:

Applying pin reset.

If you are using nrfjprog directly, try flashing GENERATED_CP_APPLICATION_merged_domains.hex to the app-core, and the GENERATED_CP_NETWORK_merged_domains.hex to the network-core
