> > @v01d and @btashton NuttX native bluetooth stack is broken now. I think
we should restore the functionality before we find a better solution. It's
wrong to support nimBLE but break the native stack for the long time.

> The fact that the NuttX stack broke was not due to a mistake during
previous PR, which this PR attempted to fix. As @btashton considered the change
to not be fully correct this PR was not merged, until he could look into the
problem. It is not a matter of prioritizing nimBLE over NuttX stack.
I think current NuttX stack is broken by this patch:
```

bluetooth: Add support for HCI RAW channel; make host layer optional
```
HCI RAW socket is selected by WIRELESS_BLUETOOTH_HOST, but the right
implementation should enable RAW mode per socket instance. If we look at how
Linux bluetooth stack work, the RAW bluesocket don't require us to remove
bluetooth stack and recompile kernel, so the RAW bluetooth socket and NuttX
native bluetooth stack isn't mutually exclusive.
