How to get current subscription status

manojnair.s

Hello All,

I'm collecting data from devices using subscription with below parameters in the request.

SubscribeCOVRequest covRequest = new SubscribeCOVRequest(
		new UnsignedInteger(1), /* Process identifier; same for all subscription requests */
		oid, /* Object identifier for subscription */
		new Boolean( false ), /* Subscription request with unconfirmed notification; done to reduce overhead on my devices */
		new UnsignedInteger( 3600 ) /* TTL in seconds */
	);

As the TTL is set for an hour, after every one hour I re-subscribe them again.

Since I'm requesting unconfirmed notification, time-to-time I'm not getting any subscription for some of the objects at all.

Is there a way by which I can get the current subscription status of an object identifier in the device?

Appreciate any response on this.

Thanks
Manoj

Hi Manoj,

I suspect you're looking for the LocalDevice's getCovContexts method, and maybe the CovReportingMixin's findCovSubscription method.

Hello Phildunlap,

Thank you very much for your quick response. Much appreciated !!

I got your point, will check on those two APIs over this weekend and let you know whether I'm able to find a solution.

Thank you very much.
