Devices

To use a measuring device with TopoDroid, the device must have been previously paired with Android.

TopoDroid has several BT connection settings: if you experience data transfer problems with the DistoX try setting "insecure" socket (see the user manual for details).

DistoX, DistoX2, and SAP5 are out of production.

BRIC4 is available at "bricsurvey.com".

The DistoXBLE board can be obtained from the FB page of the developer, Siwei Tian: first_name dot last_name dot digit_seven (all lowercase).

Automatic Station Name Assignment

It has been reported that the automatic station name assignment sometimes gets screwy.  Apparently this is an error of the Android runtime that fails to correctly transform the app to native code.
