Prior to undertaking a surveying trip, I cleared my distox memory, so that only the  Measurements taken during the surveying trip where recorded, Unfortunately After taking over 500 readings, I tried to download to my note 4, to topodroid, unfortunately the information has just disappeared into the ether, but has left the distox but is still in its memory ( Function and units key) can this be downloaded????? Or do I have to physically transcib it 🤔 many thanks

I know Topodroid allows you to clear this memory

Looks like the following might be just the ticket.

Thanks 😊  brilliant just what I was looking for 

No problems Jim 

Rob/Moose so I know, can you work with the following in your survex model? Obviously finding all the #'s and changing them to ;'s.

but would the A and a number work in survex? Would be good to know before I

My conclusion is that you can recover lost data that has disappeared between the DistoX and the phone/PDA, by using the memory on the Distox and manually writing down the information and manually entering it into your device, or if using the "TopoDroid App" using the "Dump" facility to download the data, which you then have to manually enter.
With my Buxton Water Aven data, I have manually imputed it into "Sexeytopo" which is a brilliant App apart from it freezing, I remember now thats why I shelved it and moved to TopoDroid, Jim

Or I think you could have cut out the middleman and dropped data into therion. If you want a learning session, let me know, but as you know many ways to skin the same cat!

Glad your sorted!

Thank you for a your help and support, I try to keep things as
as straight forward as possible and have found downloading a SVG file to a drawing program such as Inkscape or I-draw works best for me.
