Yesterday I did a survey of some GCP’s for Photogrammetry.
After some hours of walking in the region, and a lot of points collected, I returned to the office to download the surveyed points with RTK method (Emlid Reach on Base, and Emlid Reach on Rover… corrections via TCP)
For my sadness, the surveys that I do were corrupted, and I lost some collected points.
I’m followed this closed topic , because I faced this problem in the past… but aparently the problem was not fixed.
Both BASE and Rover are using the latest version: 2.13.0 dev
Another strange behavior that I noticed in the field, is that after press “Accept” button in survey window, aparently the ReachView disconnects… and a symbol of “waiting” remains forever… I just can access the survey section again reloading the page in my navigator.
I catch some screens ( and ) of my mobile in order to help in this question.
I downloaded the “geodata.geojson” files using the instructions in this post . When try to use a Chrome browser to export do csv/shape/etc the interface of ReachView disconnects too, and the “wait” icon turns forever 
I would like to suggest your developpers that look at sqlite3 library . We worked with this library for years in a embeded aerial systems… its a self contained SQL engine, but with high reliabitly in cases where the FS or the SO interrupt abruptaly or fail (power loss, e.g.) … do some testing with it.
