To activate message buffering, issue the following command:

lorafwdctl database.enable true

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

Then restart the packet forwarder:

monit stop lorafwd 
monit stop lorad
monit start lorad 
monit start lorafwd

• FW < 4.3.3:

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

• FW >= 4.3.3:

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

# 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

Uncomment the variable limit.messages. Modify the value then restart the packet forwarder:

monit stop lorafwd
monit stop lorad
monit start lorad
monit start lorafwd
