Slackware(64) 14.2 - Someone had detailed tutorial how configure Bluetooh ?

inukaze · 11-14-2021, 04:51 PM

Hi there again, like before i am trying to make a good configuration for Slackware(64) 14.2 using a new USB Doongle for connect Bluetooh

before i ask on this thread -> https://www.linuxquestions.org/quest...th-4175692230/

But i got the same situation.

I don't use "PulseAudio", "Avahi" and/or "SystemD", i don't understand why is the obsession of developers to put that 3 things like must be obligatory use on any GNU/Linux distro, when "Avahi" & "PulseAudio" are just optional components.

blueman can detect devices, but from the GUI i can't send/recieve files from bluetooh. because the option for send ever is disabled.

the weird is, if i use command-line with "blueman-sendto" i select file, the file is send correctly

trying to connect a bluetooth headphones N65S / N65BT, is trusted and paired, but i can't find the way to send audio from pc to headphones

The first thing i try was : Install the necesary packages :

Code:

su -c 'echo -e "'"y\n"'" | slpkg -s slack --reinstall \
bluez bluez-firmware ; \
modprobe btusb ; ldconfig' root

su -c 'echo -e "'"y\n"'" | slpkg -s sbo --rebuild --reinstall \
pybluez bluez-alsa bluez-sixaxis blueman  gnome-bluetooth ; \
ldconfig' root

Second i had create a file for "PIN" code :

Code:

su -c 'editor /etc/bluetooth/pin' root

3 - Trying to enable the "send file" on "blueman-applet" on internet i saw an example to create the follow file

Code:

su -c "editor /usr/bin/obex_thunar.sh" root

content :

Quote:

#!/bin/bash
[ ! -d "$HOME/Descargas/Bluetooh/" ] && mkdir "$HOME/Descargas/Bluetooh"
fusermount -u "$HOME/Descargas/Bluetooh"
obexfs -b $1 "$HOME/Descargas/Bluetooh"
thunar "$HOME/Descargas/Bluetooh"

Set permissions :

Code:

su -c "chmod a+o+x /usr/bin/obex_thunar.sh" root

4 - On my searching i found this on some part of this forum :

Code:

su -c 'editor /etc/udev/rules.d/50-start-bt-when-added.rules' root

Content

Quote:

# Al Detectar un dispositivo Bluetooth añadirlo a lista e iniciar el
# servicio.

# Opcionalmente detener el servicio bluetooh cuando un dispositivo es
# eliminado de la lista :
SUBSYSTEM=="bluetooth", ACTION=="remove", RUN+="/etc/rc.d/rc.bluetooth stop"

Code:

su -c "mkdir -p /etc/alsa ; \
editor /etc/alsa/bluetooth.conf" root

well nothing i had try works for that 2 things
1 - send/recieve files from bluetooth devices
2 - send audio from pc to bluetooth headphones

after of 36 hours continues, i start to thing the developers of alsa really hate alsa, becuase just make much complex set up things should be easy.

i had read a lot of sites like :

https://forum.armbian.com/topic/6480...ot-pulseaudio/

https://www.linuxquestions.org/quest...pc-4175663681/

Well nothing looks like works, and i not going to install pulseaudio, is preferible install Windows before install PulseAudio / SystemD and/or Avahi, because make a GNU/Linux distros works too much similar to Windows ME + Vista + 8.1.
