Hi Kai,
yes QoS zero should be ok for the subscription, the request message and the response message. Since a command is a synchronous interaction from the application to the device, if for any reason a response is not received, for example because of a message that was not delivered, the application knows that something went wrong and can take some action to handle the case.
While checking the documentation for Hono Command&Control [1], I noticed a couple of things that I wanted to ask you.
In the paragraph "Command & Control over MQTT Adapter" you say that requests are sent to:
- control/[tenant]/[device-id]/req/<req-id>/<command>
while responses are received from:
- control/[tenant]/[device-id]/res/<req-id>/<status>
In the picture however the <command> and the <request-id> are swapped. I suppose the first one is the right one, is that correct ? If so, then it matches the proposal no.2 at page five of the Toulouse document, which is fine.
Regarding the <command>, is that a single token or can it be a sequence of tokens ? The second would be easier to manage for us (and for Kura) since Kura commands are can be something like "CONF-V1/GET/configurations". Do you plan to have some well-known piece of information after the <command> in the future ?

Is that still your understanding of how it should work as well, i.e. the MQTT adapter will send a command to a device once and will then forget about it, right? I think this makes sense but I just wanted to reassure that we are on the same page... > > Regards, > Stefano > > > From: iot-wg-integration-bounces@xxxxxxxxxxx <iot-wg-integration-bounces@eclips > e.org> on behalf of Marc Pellmann <pellmann@xxxxxxxxx> > Sent: Wednesday, June 27, 2018 10:13 AM > To: Carrer, Marco; iot-wg-integration@xxxxxxxxxxx > Subject: Re: [iot-wg-integration] Notes from last week's integration meeting > > Hi Marco, > > you had it all in a Google Docs document you wanted to share, didn't you? > > Thanks, > Marc > > On Tue, Jun 26, 2018 at 5:04 PM Benjamin Cabé <benjamin.cabe@eclipse-foundation > .org> wrote: > > ping? :-) > > > > > On Jun 18, 2018, at 3:52 PM, Benjamin Cabé <benjamin.cabe@eclipse-foundatio > > > n.org> wrote: > > > > > > Hi, > > > > > > Can someone please remember to share here (and on iot-wg mailing list) the > > > minutes of last week’s integration meeting in Toulouse? > > > > > > Thanks! > > > Benjamin - > > > _________ > > > > > > Benjamin Cabé > > > IoT Program Manager > > > > > > Eclipse Foundation > > > +33 (0) 619196101 > > > @kartben > > > > > > > > > _________ > > > > Benjamin Cabé > > IoT Program Manager > > > > Eclipse Foundation > > +33 (0) 619196101 > > @kartben > > > > _______________________________________________ > > iot-wg-integration mailing list > > iot-wg-integration@xxxxxxxxxxx > > To change your delivery options, retrieve your password, or unsubscribe from > > this list, visit > > https://dev.eclipse.org/mailman/listinfo/iot-wg-integration > > _______________________________________________ > iot-wg-integration mailing list > iot-wg-integration@xxxxxxxxxxx > To change your delivery options, retrieve your password, or unsubscribe from > this list, visit > https://dev.eclipse.org/mailman/listinfo/iot-wg-integration _______________________________________________ iot-wg-integration mailing list iot-wg-integration@xxxxxxxxxxx To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/iot-wg-integration |
