Problem on nRF9160 making a modified lte_ble_gateway sample

Question

Our application on a nRF9160 to act as intermediary between an AWS cloud and another nRF devicee over bluetooth. So I attempted to merge the bluetooth IOT sample with the bluetooth portion lte_ble_gateway sample

When I tried running this I got this crash in the early portion of the bluetooth intialization, before any IOT code is running.

[00:00:00.251,251] <inf> health_hub: The AWS IoT sample started, version: v1.0.0

net_buf_put(&bt_dev.cmd_tx_queue, net_buf_ref(buf));

err = k_sem_take(&sync_sem, HCI_CMD_TIMEOUT);

BT_ASSERT_MSG(err == 0, "command opcode 0x%04x timeout with err %d", opcode, err);

Somewhere in the k_sem_take() we get that error 11 but it isn't clear what it is looking for at that point and stepping in doesn't work well.

Any ideas of what sort of problem can give this error?

Here is the prj.conf in case this is a missing configuration problem or something
