From 05672a2c14a4ea20b7e31a1d8d847292c2b60c10 Mon Sep 17 00:00:00 2001 From: Abhishek Pandit-Subedi Date: Tue, 22 Dec 2020 10:16:27 -0800 Subject: [PATCH] Bluetooth: btrtl: Enable central-peripheral role 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".
