SimpleComponents / MQTT

[slos <new.stephane.los@gmail.com>]

Hello Dmitry,
I'm having fun playing with SimpleComponents MQTT implementation and I have some questions...

I'm on Debian Sid using :
GNAT Studio 23.0w (20220512) hosted on x86_64-pc-linux-gnu
GNAT 11.3.0 targeting x86_64-linux-gnu

GNAT Studio
(c) 2001-2022 AdaCore

Building the test application is fine using :
gprbuild -d -P/home/slos/Ada/SimpleComponents/components_4_62/test_components/components-connections_server-mqtt-test_mqtt.gpr -XObject_Dir=. -Xarch=x86_64 -XTarget_OS=Windows -XDevelopment=Debug -XLegacy=Ada2012 -XAtomic_Access=auto -XTasking=Multiple -XTraced_objects=Off /home/slos/Ada/SimpleComponents/components_4_62/test_components/test_mqtt_client.adb

Running using either "test.mosquitto.org" or local mosquitto gives an exception after some messages received :
Exception raised
raised GNAT.SOCKETS.SERVER.CONNECTION_ERROR : gnat-sockets-server.adb:1145

I don't recall having got exceptions with Gnat Community 2021 on Windows.
Could you please have a look on that behaviour ?

It should be possible to use user name and password but I haven't found how with your implementation.
Could you tell please ?

Of course, one should use TLS in this case. Is it feasible and how ?

Also, how to provide a timestamp ?

Thanks a lot for your kind support.

Best Regards,
Stéphane
