Like the c630, the OnePlus 6 is also capable of using both antenna
channels for 2.4 and 5ghz wifi, however unlike the c630 only the first
channel is used for bluetooth.

Just for the record, I added it for completeness, as far as I can tell,
the bluetooth driver itself won't use the second channel.

Ah I see, I can confirm that the bluetooth hardware is only connected to the first channel on the op6, so with wifi off
the second antenna can also be turned off to save power without affecting bluetooth signal strength.
