Building Java based Kaa actor gateway

由 自作多情 提交于 2019-12-06 13:38:43
I would like to build a kaa actor gateway using java SDK. The actuator should handle data from different endpoints (temperature sensor - humidity sensor - ...), and log their data to the kaa platform. How can be this done what sachems I should define from Admin console and what are the API I should use from the generated SDK? I can't find any example for this in the kaa sandbox sample projects You can find more details about kaa actor gateway here . Also, there is a ticket with detailed description to create actor gateway demo application. I hope that this information will be helpful. 来源：
