CI3RC2 Sqlite3 not returning data

I'm using codeigniter 3rc2 and Sqlite3 on an embedded device running ubuntu. Server and php are configured correctly. When I try to retrieve data from the database It returns an empty query object.
Things I tried and excluded as a problem :

• access and reading from the database works when using Python (there is data in the database)
  
  
  
• no errors in codeigniter logs
  
  
  
• when changing the /config/database.php to an non existing file, codeigniter throws an error as expected
  
  
  
• when using querybuilder or sql, same result, no data
  
  
  
• when changing the SQL syntax to an non existing table, codeiginiter throws an error as expected.
  
  
  

So what am I doing wrong here?

some codeigniter code

Code:

$q_user = $this->db->query('select * from users');
var_dump($q_user);

result in browser window

Code:

object(CI_DB_sqlite3_result)#25 (8) { ["conn_id"]=> object(SQLite3)#22 (0) { } ["result_id"]=> object(SQLite3Result)#24 (0) { } ["result_array"]=> array(0) { } ["result_object"]=> array(0) { } ["custom_result_object"]=> array(0) { } ["current_row"]=> int(0) ["num_rows"]=> NULL ["row_data"]=> NULL }

config/database.php

Code:

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
   'dsn'   => '',
'hostname' => '',
'username' => '',
'password' => '',
'database' => '/var/qcd/qcd.db',
'dbdriver' => 'sqlite3',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'autoinit' => TRUE,
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);

PHP Code:

$query = $this->db->query('select * from users');
 
print_r($query);
 
foreach ($query->result_array() as $row)
 
{
 
   echo "<div>".print_r($row)."</div>";
 
} 


Seems like I was reading the wrong object. printing the $q_user object only shows the objects in it, not the data arrays. When I use this code, it shows the retrieved data
