I'm having a bit trouble here getting migrated to LPUART on a working nRF9160 <> HCI BLE on nRF52 (On the Thingy91). As far as I can tell my .conf and .overlay files are what they should be. Are there any other gotchas that I may be missing here? I get an HCI timeout when initializing bluetooth:

I'm probably doing something stupid here but any insight would be extremely appreciated!
In the meantime I'll keep chugging on it here.
Thanks!
