Winter is here and this is the season for maintenance, calibration and updates. For those of you working with Esri ArcPad, ArcGIS for Windows Mobile and Trimble Positions on a Trimble Geo 7x, we are recommending staying on OS version 6.7.15. The latest update to the Geo 7x OS (6.7.16) is currently experiencing memory loss issues. The details are listed in the Trimble Positions Development Team Blog post listed below.
Earlier this year, an operating system update (6.7.16) was released for the Geo 7X handheld. Support cases submitted to both Trimble and Esri have indicated that ArcPad users with complex projects are running up against memory problems with increased frequency after upgrading their devices to this new OS version. Customer and dealer testing indicates that there is ~4MB less memory available to the application compared to the old OS version.
This issue is being investigated internally. Initial testing suggests that any high-memory use application could be affected including ArcPad and ArcGIS for Windows Mobile + Trimble Positions. At this time, it is recommended that Trimble Positions users with larger field projects stay at the previous operating system version (6.7.15) until further notice.
If you have already updated to the latest software, not to worry. You are able to revert back to 6.7.15, all you need to do is download the 6.7.15 file and reinstall it on your Geo 7x using Windows Mobile Device Center.
