Hi @triampmeili

Regarding the excel database, I’m not sure what you are trying to do. We do have a [single file update module](https://hub.mender.io/t/single-file/486/25) that will copy one file onto the target.

As for the device connection time, it’s hard to say. Devices need to have a synchronized time source using NTP before the TLS certificates can be validated. That can be one source of delay. If you can provide the output from running `journalctl -u mender-client` on the device that took so long, we may be able to see other things.
