RE: How to change publish address on nrf skd connect

Hi,

We have an example of this type of behavior in the Bluetooth: Mesh chat example, where the chat model can publish to arbitrary addresses. How this works is described in detail on the Chat sample walk-through page. (Search for "sending of private messages" on that page.) Basically it uses bt_mesh_model_send() with a custom made context:

int bt_mesh_chat_cli_private_message_send(struct bt_mesh_chat_cli *chat,
					  uint16_t addr,
					  const uint8_t *msg)
{
	struct bt_mesh_msg_ctx ctx = {
		.addr = addr,
		.app_idx = chat->model->keys[0],
		.send_ttl = BT_MESH_TTL_DEFAULT,
		.send_rel = true,
	};

	BT_MESH_MODEL_BUF_DEFINE(buf, BT_MESH_CHAT_CLI_OP_PRIVATE_MESSAGE,
				 BT_MESH_CHAT_CLI_MSG_MAXLEN_MESSAGE);
	bt_mesh_model_msg_init(&buf, BT_MESH_CHAT_CLI_OP_PRIVATE_MESSAGE);

	net_buf_simple_add_mem(&buf, msg,
			       strnlen(msg,
				       CONFIG_BT_MESH_CHAT_CLI_MESSAGE_LENGTH));
	net_buf_simple_add_u8(&buf, '\0');

	return bt_mesh_model_send(chat->model, &ctx, &buf, NULL, NULL);
}
