this is the output of systemctl status bluetooth.service

I also created a btattach.service with this code

[Unit]
Description=Btattach

[Service]
Type=simple
ExecStart=/usr/bin/btattach --bredr /dev/ttyS1 -P bcm
ExecStop=/usr/bin/killall btattach

[Install]
WantedBy=multi-user.target

following a guide on an arch forum regarding this laptop

Bluetooth

Install a correct firmware file (e.g. BCM43341B0_002.001.014.0122.0176.hcd from Windows 10 driver) as /lib/firmware/brcm/BCM43341B0.hcd.

In order to get bluetooth working create a systemd unit

/etc/systemd/system/btattach.service

[Unit] 
Description=Btattach 

[Service] 
Type=simple 
ExecStart=/usr/bin/btattach --bredr /dev/ttyS1 -P bcm
ExecStop=/usr/bin/killall btattach 

[Install] 
WantedBy=multi-user.target

and [enable] the service.

Next, follow the normal steps to activate [bluetooth]

Could someone give me a hint on how to find a solution to this problem?

Thanks!
