Mosquitto 1.6.2 Testing - Unable to get QoS 1 messages after persistent session reconnects

[Ezequiel Colombo]

Trying to test [MQTT-3.1.2-5] I'm not being able to get QoS 1 messages stored/delivered at client's reconnect with cleanSession=False even though using the same clientID, QoS1.

I've already tried default mosquitto config with same results and switched from Python PAHO client to mosquitto_sub/mosquitto_pub with same unsuccessful result ... could someone share a working config for this or help me troubleshoot deeper ?

Mosquitto 1.6.2 @ RaspberryPI config:

pid_file /var/run/mosquitto.pid

persistence true

persistence_location /var/lib/mosquitto/

autosave_interval 1800

log_dest file /var/log/mosquitto/mosquitto.log

log_type all

acl_file /etc/mosquitto/conf.d/acl_file

password_file /etc/mosquitto/conf.d/password_file

allow_anonymous false

message_size_limit 64000

persistent_client_expiration 1d

max_queued_messages 256

max_queued_bytes 2048

max_connections 64

sys_interval 30

log_timestamp true

connection_messages true

listener 8883

cafile /etc/mosquitto/ca_certificates/ca.crt

keyfile /etc/mosquitto/certs/server.key

certfile /etc/mosquitto/certs/server.crt

 Testing commands:

mosquitto_sub -h localhost -u someuser -P 1234 -i perstest -q 1 -t test/after/one -d

mosquitto_pub -h localhost -u someuser -P 1234 -t test/after/one -q 1 -d -c --id pub1 -m 01

.. message "01" received ok

CTRL-C mosquitto_sub then:

mosquitto_pub -h localhost -u someuser -P 1234 -t test/after/one -q 1 -d -c --id pub1 -m 02

mosquitto_pub -h localhost -u someuser -P 1234 -t test/after/one -q 1 -d -c --id pub1 -m 03

mosquitto_pub -h localhost -u someuser -P 1234 -t test/after/one -q 1 -d -c --id pub1 -m 04

mosquitto_sub -h localhost -u someuser -P 1234 -i perstest -q 1 -t test/after/one -d

.. no "02", "03", "04" messages received

mosquitto_pub -h localhost -u someuser -P 1234 -t test/after/one -q 1 -d -c --id pub1 -m 05

.. message "05" received OK

Thanks in advance for your help,
