[PATCH RFC 0/4] Add WCN3988 Bluetooth support for Fairphone 4
From: Luca Weiss
Date: Fri Apr 21 2023 - 10:11:53 EST
Just to start with the important part why this is an RFC:
While Bluetooth chip init works totally fine and bluez seems to be
fairly happy with it, there's a (major) problem with scanning, as shown
with this bluetoothctl snippet and dmesg snippet:
[bluetooth]# scan on
Failed to start discovery: org.bluez.Error.InProgress
[ 202.371374] Bluetooth: hci0: Opcode 0x200b failed: -16
This opcode should be the following:
include/net/bluetooth/hci.h:#define HCI_OP_LE_SET_SCAN_PARAM 0x200b
Unfortunately trying various existing code branches in the Bluetooth
driver doesn't show any sign of making this work and I don't really know
where to look to debug this further.
On the other hand "discoverable on" makes the device show up on other
devices during scanning , so the RF parts of the Bluetooth chip are
generally functional for sure.
Any ideas are welcome.
@Bjorn: Patch "arm64: dts: qcom: sm6350: add uart1 node" should be fine
to take regardless the RFC status, I don't think the problem is caused
there.
