Re: PS4 Bluetooth Controller

Found it. Forgot to trust the controller in bluetoothctl:

Code: Select all

[bluetooth]# trust 1C:96:5A:53:C1:C3
[CHG] Device 1C:96:5A:53:C1:C3 Trusted: yes
Changing 1C:96:5A:53:C1:C3 trust succeeded
[CHG] Device 1C:96:5A:53:C1:C3 Connected: yes
It now stays on.

PS4 Bluetooth Controller

Maybe this should be in the Retropie forum but this seems like a low-level thing so I'll start here. I have a PS4 DS controller. It's all paired to my Pi 2 and displays in both bluetoothctl and hcitool. When I press the PS button, the controller flashes three times and turns off. In bluetoothctl I s...

Re: Bluetooth Is Disabled After Every Reboot

Yeah, I did all that. I probably did something heinous and untoward to this install in previous days. It's an old Retropie install. I played with bluetooth on it long ago. Doing the manual Jessie to Stretch upgrade was a (failed) experiment. Time to start with a clean distro install. Many thanks for...

Bluetooth Is Disabled After Every Reboot

I have a Pi 2 that I manually upgraded from Jessie to Stretch (that was a mistake - took hours).

I cannot seem to enable bluetooth persistently.

Code: Select all

sudo systemctl enable bluetooth
Seems to enable bluetooth but on reboot it is disabled again. Something to do with SysV runlevels.

Any ideas?

Re: FSTrim/Discard Recommended?

A posting says the the lsblk -D command tells you if trim is supported: $ lsblk -D NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO mmcblk0 0 4M 976M 1 |-mmcblk0p2 3145728 4M 976M 1 `-mmcblk0p1 3145728 4M 976M 1 This seems to say it *is* supported.

Re: FSTrim/Discard Recommended?

A bit more research on SSDs. So basically you do *not* mount with discard and instead occasionally run fstrim via the timer:

Code: Select all

/usr/share/doc/util-linux/examples/fstrim.service
/usr/share/doc/util-linux/examples/fstrim.timer

FSTrim/Discard Recommended?

I have a Raspian based distro (FreePBX) and am wondering if running fstrim and mounting the filesystem with discard is recommended? I see the SSD documentation:

https://wiki.debian.org/SSDOptimization

But I am unsure how this applies to Micro-SD cards.

Thanks.
