From cb0891eee395cf09a822b521cebfa973bbf8c1d5 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Mon, 1 Mar 2021 09:12:44 +0000 Subject: [PATCH] Revert "Bluetooth: Always request for user confirmation for Just Works (LE SC)" This reverts commit ffee202a78c2980688bc5d2f7d56480e69a5e0c9. The commit "Bluetooth: Always request for user confirmation for Just Works" prevents BLE devices pairing in (at least) the Raspberry Pi OS GUI. After reverting it, pairing works again. Although this companion commit ("... (LE SC)") has not been demonstrated to be problematic, it follows the same logic and therefore could affect some use cases. If another solution to the problem is found then this reversion will be removed.
