Subject: [PATCH] Bluetooth: btrtl: Enable central-peripheral role
Date: Tue, 22 Dec 2020 10:16:27 -0800 [thread overview]
Message-ID: <20201222101603.1.I94935e7936550207ae745d3670890541c792c35e@changeid> (raw)
Enable the central-peripheral role on RTL8822CE. This enables creating
connections while there is an existing connection in the slave role.
This change can be confirmed in userspace via `bluetoothctl show` which
will now show "Roles: central-peripheral".
