Re: Problems with LooCI
Klaas Thoelen
I've never seen this error. What SunSPOT sdk version are you using? We developed LooCI using the red version, which also is the only one on which we thoroughly tested LooCI.
Could you maybe describe to me the steps that you are taking to do the deployment?
Concerning communicating between different WSNs, we have implementations of LooCI for SunSPOTs, Contiki (on AVR Raven nodes) and OSGi and have done successful tests with connecting nodes from different implementations to each other. This however always requires some sort of proxy between the various networks since on lower levels than where LooCI resides in the networking stack, SunSPOTs cannot communicate directly with the AVR Ravens or other devices running OSGi. Between SunSPOTs and OSGi we used a proxy at the event bus level, while between the AVR Ravens and the OSGi nodes we could use simple IP routing as both platforms are IP enabled.
I hope this helps a bit.
Best regards,
Klaas
