The MQTT driver have a new parameter added from 1.1.0.22 Sodium. Previously the parameter format was
"subscribe”|”publish”;channel;host;user;password;keepalive;filter;mask
the new format is
“sessionid";"subscribe”|”publish”;channel;host;user;password;keepalive;filter;mask
where sessionid is a unique session string, That is if you have several MQTT drivers in your VSCP daemon configuration file each of them should have a unique sessionid.
I usually try to make things backward compatible but it was not logical to place the sessionid at the end in my opinion.
