The Message buffering feature initially introduced in the Server Software release 3.1 has been really improved with the Server SW release 3.2.7 and Gateway FW release 4.3.3.

Now, there is a new field called “Gateway received time” displayed in Dashboard for the DataUp messages. Care, this field is different from the field “Date”.

• Gateway received time: is the reception timestamp on the gateway.
• Date: is the reception timestamp on the server when the message has really been sent by the gateway.

So there is a change in dashboard, see screenshot below:

Note that the push API has been also altered by the adding of this new field:
