====== FAQ: Message Buffering ======

===== How to activate the message buffering on my gateway? =====

To activate message buffering, issue the following command:

<code>lorafwdctl database.enable true</code>

You can verify that the feature is enabled by reading the database.enable variable in the configuration file specified in ''/etc/default/lorafwd''

  * For FW < 4.3.3 :

<code>

root@klk-lpbs-050792:~ # cat /etc/default/lorafwd
# Configuration file for lorafwd.

# The configuration file.
# The configuration files can be found in: /user/etc/lorafwd
CONFIGURATION_FILE="/user/etc/lorafwd/lorafwd.toml"

# The extra arguments.
EXTRA_ARGS="-v"

root@klk-lpbs-050792:/etc/default # grep -i -A10 "\[ database \]" /user/etc/lorafwd/lorafwd.toml
[ database ]

# Whether or not a persistent database will store the incoming messages until
# they will be sent and acknowledged.
#
# Type:    boolean
# Example: true
# Default: false
#
enable = true

</code>

   * For FW >= 4.3.3 :

<code>

root@klk-lpbs-050792:~ # cat /etc/default/lorafwd
# Configuration file for lorafwd.

# The configuration file.
# The configuration files can be found in: /etc/lorafwd
CONFIGURATION_FILE="/etc/lorafwd/lorafwd.toml"

# The extra arguments.
EXTRA_ARGS="-v"

root@klk-lpbs-050792:/etc/default # grep -i -A10 "\[ database \]" /etc/lorafwd/lorafwd.toml
[ database ]

# Whether or not a persistent database will store the incoming messages until
# they will be sent and acknowledged.
#
# Type:    boolean
# Example: true
# Default: false
#
enable = true

</code>
\\
Then restart the packet forwarder:
<code>
monit stop lorafwd
monit stop lorad
monit start lorad
monit start lorafwd
</code>

===== How to configure the number of messages in database ? =====

<note important>
The default value is 200 messages stored in the database. \\
The maximum value is 1000 but **Kerlink does not recommend to change the default value of 200 to avoid system load issues**. 
</note>

  * FW < 4.3.3:

<code>
root@klk-lpbs-050792:/etc/default # grep -i -A10 "\[ limit.messages \]" /user/etc/lorafwd/lorafwd.toml
</code>

  * FW >= 4.3.3:

<code>
root@klk-lpbs-050792:/etc/default # grep -i -A10 "\[ limit.messages \]" /etc/lorafwd/lorafwd.toml
</code>

<code>
# The maximum number of messages allowed to be stored in the database. When
# full the newest message will replace the oldest one.
#
# Type:    integer
# Example: 20000
# Default: 200
#
#limit.messages = 200
</code>

Uncomment the variable limit.messages. Modify the value then restart the packet forwarder:
<code>
monit stop lorafwd
monit stop lorad
monit start lorad
monit start lorafwd
</code>
