Subscribe issue

[barrygordon]

I am using an ISY 99i with the X10 module installed. I am running ISY firmware 3.3.10.

I control the ISY using ipads, there being 5 of them wall mounted in my home.

I subscribe to ISY events. What appears to be happening is that only the last iPad that has subscribed to events receives event notification.

 

Is this correct? How many systems can be simultaneously subscribed to events on a single iPad.?

 

Here is the communication sequence that happens when I start a subscription: (sent to port 80 of the ISY on 192.168.1.229)

 

> startSubscribe: msg sent=

SUBSCRIBE(SP)/eventing(SP)HTTP/1.1(CR)(LF)HOST:(SP)192.168.1.229(CR)(LF)Authorization:(SP)Basic(SP)YWRtaW46YWRtaW4=(CR)(LF)Content-Length:129(CR)(LF)Content-Type:text/xml;(SP)charset="utf-8"(CR)(LF)CALLBACK:(CR)(LF)NT:upnp:event(CR)(LF)TIMEOUT:second-infinite(CR)(LF)SOAPACTION:"urn:udi-com:service:X_Insteon_Lighting_Service:1#Subscribe"(CR)(LF)(CR)(LF)(CR)(LF)

 

ISY.subscribeFeedback: FBstring=

This is then followed by sequence numbered events as they occur, but only to this system. Other systems (ipads) which had previously submitted the subscribe request no longer get event notifications.

 

Any advice appreciated.

I use the following command to subscribe:

 

POST /services HTTP/1.1
Host: 192.168.0.129:80
Authorization: Basic YWRtaW46YWRtaW4=
Content-Length: 193
Content-Type: text/xml; charset="utf-8"

I know its more than one and I'm almost sure it more than 10, it's written somewhere but can't locate it at the moment.
