There was some discussion in the past about having simple devices like 
these contain an OSGi bundle in their firmware (or a URL to their bundle 
kept elsewhere). Then when the device was discovered by a gateway running 
OSGi, part of the discovery would present the bundle to the OSGi framework 
for installation. UPnP was one suggested means of this.

Re: [osgi-dev] OSGi + Sun Spot



Hi Ken,

thanks !

did you get it from the slides that some spots also implemented the 
driverlocator interface, thus being able to provide
the device manager with the drivers to their own services ? how neat is 
that ?

to answer your question:

well, on the spots themselves, i don't know... Since they _only_ support 
CLDC 1.1
supporting osgi on the spots seems far fetched..., but imagine that each 
spot is something like an osgi bundle, exporting a service
but also depending on services being exported by other sunspots. just 
putting several bundles in each other's vicinity would more or less create 
a set of bundles
i.e. an osgi-like application. removing a sunspot would then be like 
removing a bundle. Replacing a sunspot would then be like replacing a 
bundle. you get the picture...

their means of communication should be simple and generic like upnp, which 
is far too heavy, I think.

Hi Dennis,

 Very cool!  In your Future Plans section of the slides you mention
getting OSGi on the spots.  Have you done this?  We have some spots at
Bug Labs we're playing around with. 

cheers

Yes, I have. I've been using SunSPOTs together with the device access
specification. 


The BaseStation application was an OSGi application. This application
was able to detect
SunSPOTS by means of a very, very lightweight discovery protocol. As
soon as a SunSPOT was
detected, the device access spec was used to bind such a remote
application to a specific service inside the basestation application.
As soon as the connection to the SunSPOT was lost (due to the distance
being too large, or the SunSPOT
was turned off), the service was automatically removed.


In short my experience was a pretty good one.


please don't hesitate to get in touch if you would like to receive
more detailed information.


I'd also recommend you taking a look at the slides I made for a
presentation about my work:


SunSPOT Flexibility with OSGi


(http://www.google.nl/search?hl=nl&q=sunspot+osgi&btnG=Zoeken&meta=)
item 1,2 and 3 ;-)


Sincerely, Dennis

Hi,

Simple question, has anyone been using OSGi with sun spot devices?
How is/was your experience?
