In Digi Embedded Linux DEL-5.7.2 there are some "iDigi" examples, which do connect the device to the cloud. From the cloud device manager it allows you to change e.g. IP settings, or to browse the file system.
The examples are:
just use the DEL Eclipse Help > search for them.
Or Open the Help contents Digi ESP for Embedded Linux
section 13 iDigi platform
Even firmware update through the cloud should be possible.
The storage example does not work any more due to API changes. Digi would need to update the storage example to new API, or you cross compile the ANSI C embedded cloud connector, which is available on request from Digi Technical Support.
