I found out that it is possible to drop .tpk files on mobile devices running Collector for ArcGIS to avoid downloading basemap. (http://blogs.esri.com/esri/arcgis/2014/03/23/using-your-own-basemap-layers-with-collector-for-arcgis/).
It comes to our minds that it would be great to push this file remotely to every IPad we are using to update them regularly with the last data.
It is possible some application thanks to Mobile Device Management (MDM) of Apple. You can find in the link below more information about it :
Would anybody know by any chance, if Collector supports Managed Configuration and if yes, what are the settings that can be pushed ?
Thanks in advance,
