Dualshock 4 not connecting on boot.

w3ss

I have the exact same problem running retropie 4.1 without hidraw.

Can connect both remotes when starting the script manually but when rebooting in retropie noting is detected.

Maybe the script isn't starting in rc.local?

You can find out if it is running. After startup, you'll need to ssh into your raspberry pi and run the following command. Paste the output here.

ps ax | grep python3

Naroth

pi@retropie:~ $ ps ax | grep python3
1024 pts/0 S+ 0:00 grep --color=auto python3
pi@retropie:~ $

that is what i get when i type in "ps ax | grep python3"

Naroth

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution

# By default this script does nothing.
/usr/local/bin/ds4drv --led 000008 &

 exit 0

and thats how my local file looks..

Based on the output of the of the command you ran, the script is not running. However, I'm not sure why it isn't running as your rc.local looks correct.

If you cd to
/usr/local/bin

The script is there correct?

Naroth

what do you mean cd? :P

michaelconsorti

It's a unix command to change directory.

ssh back into your retropie and type in

cd /usr/local/bin

then

ls -lrta

Naroth

pi@retropie:/usr/local/bin $ ls -lrta
total 12
drwxrwsr-x 10 root staff 4096 Sep 23 02:20 ..
-rwxr-xr-x 1 root staff 217 Jan 7 15:13 ds4drv
drwxrwsr-x 2 root staff 4096 Jan 7 15:13 .

michaelconsorti

Everything looks OK there too. Does your rc.local file have '#' symbols before some of the lines. i.e.

#This script is executed at the end of each multiuser runlevel.

Naroth

yes, the only lines that doesnt have it is

/usr/local/bin/ds4drv &
exit 0

Naroth

Anyone got any idea?

if it's not launching from /etc/rc.localthen you will probably find it is failing in some way. Run it manually from terminal with

/usr/local/bin/ds4drv

and see if you get any errors.

BuZz

@Naroth Format code in code blocks - http://commonmark.org/help/ - otherwise # symbols will be translated to styling. See your previous posts (I edited the one with /etc/rc.local as an example).

Naroth

@BuZz it works if i run it manually.

BuZz

@Naroth check /var/log/syslog for errors. make sure /etc/rc.local has executable permissions too. you could output errors to a log /usr/local/bin/ds4drv 2>/var/log/ds4drv.log & and then check that

Naroth

@BuZz will do when i get home. don't know how to check if it /etc/rc/local has persmissions though, so new at this. lol

BuZz

@Naroth ls -l /etc/rc.local

Naroth

@BuZz

this is what i get when running those commands

pi@retropie:~ $ ls -l /etc/rc.local
-rwxr-xr-x 1 root root 333 Jan 11 22:16 /etc/rc.local
pi@retropie:~ $ /var/log/syslog
-bash: /var/log/syslog: Permission denied
pi@retropie:~ $ /usr/local/bin/ds4drv 2>/var/log/ds4drv.log &
[1] 1239
pi@retropie:~ $ -bash: /var/log/ds4drv.log: Permission denied

BuZz

@Naroth Format your posts as I have already detailed.

permissions on /etc/rc.local are ok

I didn't say to type the other things. The line /usr/local/bin/ds4drv 2>/var/log/ds4drv.log & is supposed to be in /etc/rc.local (before the exit 0)

You can then check the log by typing cat /var/log/ds4drv.log

Recommend you do some reading on using the terminal. some info here - https://github.com/retropie/retropie-setup/wiki/ssh and lots of tutorials online.

@BuZz

yeah as i said i know nothing about this.. but i added "/usr/local/bin/ds4drv 2>/var/log/ds4drv.log &" in /etc/rc.local
then i ran "cat /var/log/ds4drv.log" and i got pi@retropie:~ $ cat /var/log/ds4drv.log
cat: /var/log/ds4drv.log: No such file or directory
