Unsupported: Bluetooth
There are a small amount of devices in the OpenWrt table of hardware with Bluetooth chips, but many, if not all, are not supported by the firmware. The main reason for this is that the use cases for enabling Bluetooth on these devices are limited, meaning it is generally not worth it to work for Bluetooth support. In many cases, Bluetooth on routers is only used for initial setup, making it useless on the OEM firmware as well after that stage is completed. It is mainly a gimmick that could potentially take away from router power efficiency and CPU utilization headroom.
