How to : Multiple core devices and subscriptions across all core devices

Hi MockingBird,

1. No. You can have a group with only a core. However, you can only have one core per group.
2. If you launch multiple groups you would setup a subscription from Lambda -> IoT Cloud and from IoT Cloud -> Lambda for each group.

Can you tell me a bit more about your use case and what you're trying to do?

Thanks,

Hi Keagen,
Thanks for your reply.
What we are trying to achieve is, we have a set of sensors, and we want to crunch the data there itself, that means we prefer to execute the lambda in each of these device, and all these devices should communicate each other to share some data for their processing, that means all these devices need to be in a group.
So could you please suggest a proper way to do the same

Thanks,

Some more clarification needed

Hi mockingBird,

Currently there isn't an easy way to communicate from core A to core B without going through the IoT Cloud. You can make core A a device for core B and vice versa. However, MQTT from device to core is only QoS 0. You'll need to handle missing/lost messages in your application.

Please let me know if you have any other questions.
Thanks,
Keagen

Thanks a lot Kaegan
