Installing Slarm64-current on the Pi 400

pchristy · 01-12-2021, 11:28 AM

Code:

 ls /dev | grep -P 'ttyAM|ttyS|serial'
serial0@
serial1@
ttyAMA0
ttyS0

Looks sorta right, but not sure about those "@" on the end?

And yes, the config.txt does contain those lines.

@ this is ok, these are symlinks, while there is nothing why it doesn't work.
rfkill what outputs?

pchristy · 01-12-2021, 11:40 AM

Code:

rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

Looks like it thinks its working!

The bluetooth icon does not appear in the system tray (kde5), unlike on my (x86_64) laptop. It is in the "hidden icons" section. When I click on it, it says "no adapters found", but if I try and "add a device", it says "scanning", but never finds the headphones I am trying to pair with it. On Raspbian, the icon is in the system tray, and it pairs almost instantly - as indeed it does with a plug-in dongle.

try blueman-manager

pchristy · 01-12-2021, 11:53 AM

Code:

blueman-manager

Looks like the same issue?

Is this any help?

"Can't initialize device:" is classed as "success" !?!

Code:

ls -l /dev | grep -P 'ttyAM|ttyS|serial'

should be

Code:

lrwxrwxrwx 1 root root           5 Jan  1  1970 serial0 -> ttyS0
lrwxrwxrwx 1 root root           7 Jan  1  1970 serial1 -> ttyAMA0

Exaga might be on to something:

Code:

lsmod | grep hci_uart
hci_uart               49152  1
btbcm                  24576  1 hci_uart
bluetooth             475136  10 hci_uart,btbcm,bnep

but the btsdio module is NOT loaded - at all!

Code:

modprobe btsdio
modprobe: FATAL: Module btsdio not found in directory /lib/modules/5.10.3

Missing module in kernel configuration? But then why does it work with a dongle?

OK,I'm still on 5.10.3 - haven't figured out how to update the kernel on slarm64 yet (I do it all the time on x86_64, but the boot folder here is very different!).

update standard download and upgradepkg

as far as I understand, the module is not sdio but uart.

Code:

hciattach /dev/serial0 bcm43xx 921600 noflow - b8:27:eb:aa:aa:aa

pchristy · 01-12-2021, 01:32 PM

Code:

hciattach /dev/serial0 bcm43xx 921600 noflow - b8:27:eb:aa:aa:aa
bcm43xx_init
Initialization timed out.

Well, the init didn't fail this time! It just timed out! Progress?
