[PROBLEM] Spotify connect keeps dropping

[adixor]

The librespot project is actively being worked on so eventually the bug will be fixed which is why at the moment I'm not planning to invest time to code some sort of watchdog for it into moOde.

But if someone wants to give it a try then here is some useful information.

librespot is started by moOde in /var/www/inc/playerlib.php function startSpotify(). This function reads the values in the sql table cfg_spotify and then composes the command string. A "restart" script would need to be written in PHP and include playerlib.php. Then it just calls startSpotify().

The watchdog part would be added to the existing /var/www/command/watchdog.sh script. The code block would be similar to the MPD restart block.

Thanks for this! Combining the information in here ^^ and in some other thread, I've got myself a nice watchdog/restart for the librespot issues. You can use this procedure:

1. login as user pi

2. Create a file in /home/pi called restartspotify.php

Code:

sudo nano /home/pi/restartspotify.php

with this contents:

PHP Code:

#!/usr/bin/php
<?php


set_include_path('/var/www/inc');
require_once 'playerlib.php';

playerSession('open', '' ,'');
session_write_close();

sysCmd('killall librespot');
sysCmd('/var/www/vol.sh -restore'); // r44d
// reset to inactive
playerSession('write', 'spotactive', '0');
$GLOBALS['spotactive'] = '0';
sendEngCmd('spotactive0');
startSpotify();

?>

3. set the script as executable:

Code:

sudo chmod +x /home/pi/restartspotify.php

4. replace the already existing file /var/www/command/watchdog.sh

Code:

sudo nano /var/www/command/watchdog.sh

with this version (which adds a check for the existence of the librespot process and calls the script above to start it again)

(for reference, compared with the original I have added these lines: 28, 47-54, 60)
 

5. Reboot and that's it!

(note: so far I only tested it by killall librespot and the process was respawned few seconds after - the watchdog checks every 6 seconds).
