Loosing Bluetooth connection after reboot

mitu

@motleypixel Just press the option for the udev rule, it's just a configuration in the system to associate a certain hardware id to the same device name, not a binary or something to be installed.
Have you checked if the MAC bluetooth address is the same each time your're re-pairing the controller ?

motleypixel

@mitu Yes MAC is always same, but for safe measures, since I am currently having to repair each time, I am removing the controller and re-pairing. Let me just select the udev option and see what that does. I'll report back.

Thank you,
Roy

@mitu okay, wondering if attract mode is causing issues here. When I went back to ES and did a whole new BT configuration, after pairing I then selected the option 1 DisplayYesNo and it thew this error at the bottom of the screen:

so I nano'ed again the autostart.sh and my sudo disable ertm line was gone??? what the heck? So I added it back, rebooted into ES and again resetup BT and got it paired, then selected the udev optiion...nice! did I miss this in the wiki somewhere? here's what is said after udev:

So I went ahead and configured inputs and then rebooted. Upon booting back into ES it worked like a charm! but that's when the goodness ended.

I then switched to attract mode and it lost connection and now w/in attract mode and ES it seems like it's not wanting to pair again...suspect the autostart.sh is reset again. hummm...seems like this BT wireless controller stuff is wasting too much of my valuable time, esp. now since I'm getting ready to leave for a trip...darn, I'm building this image for the brother-in-law and want it rock solid because he's not too computer savy.

Any other suggestions?

Thank you,
Roy

@motleypixel Either see if using ES only makes the connection persistent or use another controller with a better compatibility with Linux/Retropie ?

motleypixel

@mitu I have confirmed that ES operation only operates as it should, it auto-reconnects to the Xbox One S BT controller. However, anytime I switch to attract mode it breaks, and I can confirm that the autostart.sh resets and removes the entry I have to have for this xbox BT controller which is to disable ertm. As for the udev entry, did I miss that in the wiki? If not, then perhaps it should be added.

I would like to figure out why attract mode is breaking this configuration.

Thank you for the help,
Roy

It's not mandatory, but since udev handles - persistent - device naming, I figured out it would help. You should add the etrm fix in the /etc/rc.local file, maybe attract mode messes up the autostart.sh file.

motleypixel

@mitu So make the /etc/rc.local look like this?

#!/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

bits.

By default this script does nothing.

Print the IP address

#added as a suggestion from retropie.org forum
sudo bash -c 'echo 1 > /sys/module/bluetooth/parameters/disable_ertm'

_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi

"/opt/retropie/supplementary/retropie-manager/rpmanager.sh" --start --user pi 2>&1 > /dev/shm/rpmanager.log &
exit 0

@motleypixel Something like this. Hard to see it properly because of the formatting. You don't need sudo before the command, since the script is executed on start from the root account. With proper formatting:

# added as a suggestion from retropie.org forum 
echo 1 > /sys/module/bluetooth/parameters/disable_ertm

_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi

/opt/retropie/supplementary/retropie-manager/rpmanager.sh --start --user pi 2>&1 > /dev/shm/rpmanager.log &
exit 0

@mitu Thank you...on the road, will be giving this Raspberry Pi 3 setup to my brother-in-law on Christmas...so maybe we'll be able to do some testing early next week. I'll let you know how it goes. Also, for the formatting, I read in the "read first" post or some post about formatting, not following the "code" tags...back in the day I would wrap such text with [code] text to format [/code] I will try to figure that out. Oh and as for the disable ertm in the autostart.sh I'm assuming sudo is needed for that one? Need to test this out on my Linux Mint VM but if you are already root and sudo or sudo su - pi etc. it will still execute correct?

Thanks and Merry Christmas!

Yes, that would be needed since is executed as the pi user.
