[Pkg-bluetooth-maintainers] Bug#816865: bluez: btattach from BlueZ 5.37 needed to enable Bluetooth on recent products, such as ThinkPad Tablet 8

[Jérôme de Bretagne]

Package: bluez
Version: 5.37
Severity: important

Dear Maintainer,

BlueZ has introduced the btattach command in release 5.37, as the successor to
hciattach. It seems to be the new recommended tool to enable recently-supported
chipsets, including in particular some Broadcom combo chipsets using SDIO for
Wi-Fi and UART for Bluetooth.

This is for instance the case on the Lenovo ThinkPad Tablet 8, which is using a
Broadcom 43241 rev B5 chip. The command to enable that Bluetooth device is:

$ btattach --bredr /dev/ttyS1 -P bcm    # Sadly, this also requires a binary
firmware but that's another issue.

Could you please include this new btattach tool when you package the next BlueZ
version 5.37, and configure it in a way that it will enable such Bluetooth
chipsets directly at boot time?

I would be glad to evaluate experimental packages to confirm if this is working
properly on the ThinkPad Tablet 8 or not. Right now, I have Bluetooth working
but only in a manual way: recent Linux kernel and BlueZ 5.37 compiled locally
and btattach launched manually.

Thanks a lot,

Jérôme
