Not receiving all events

[zbrox]

I'm subscribing for a service but I'm not reliably receiving all the events. When I check all traffic with Wireshark I can see events that are incoming but are not always registering with the observer.

Is anybody else experiencing this?

Hi @zbrox , yes I have this problem as well. The reason for this is,

• that events can already arrive, while the event subscription was not process (leading to discarded events)
• that you subscribe too late, so you miss the first event, though it was eventually processed.

@fkuehne , i have a solution for this in a local fork, is this still interesting for this project? My solution has two parts:

UPnPEvents gets a buffer for all arriving events, that are not yet assignable to an observer BasicUPnPService gets a buffer for "currentStateVariableValues". Whenever an observer subscribes and state variables have arrived already, these are sent immediatly to the observer.

An observer can subsribe 'whenever' he wants, if if events arrived earlier the subscriber is guaranteed to get an initial set of current values.

@bluegaspode sure, a pull request would be welcome!
