Subject: [PATCH 0/5] Bluetooth: Improve retrying of connection attempts
Date: Tue, 2 Jan 2024 19:59:27 +0100 [thread overview]
Message-ID: <20240102185933.64179-1-verdre@v0yd.nl> (raw)
Since commit 4c67bc74f016b0d360b8573e18969c0ff7926974, the kernel supports
trying to connect again in case the bluetooth card is busy and fails
to connect.
The logic that should handle this became a bit spotty over time, and also
cards these days appear to fail with more errors than just "Command
Disallowed".
This series tries to improve the logic for retrying "HCI Create
Connection" and adds support for two more errors that can indicate the
hardware being busy.
Jonas Dreßler (5):
Bluetooth: Remove superfluous call to hci_conn_check_pending()
Bluetooth: hci_event: Use HCI error defines instead of magic values
Bluetooth: hci_event: Remove limit of 2 reconnection attempts
Bluetooth: hci_event: Do sanity checks before retrying to connect
Bluetooth: hci_event: Try reconnecting on more kinds of errors
