6.10 Status Message
6.10
The SWiFT continuously broadcasts a status message over Bluetooth when on the surface.
It allows for the status of the SWiFT to be determined without interrupting its operation.
The message is broadcast every 10 seconds and is in the form of a proprietary NMEA type
message. It contains the following information:
$PVBB,00102532,56150,50.4264,-3.6814,66.00,210118154647,0,*42

6.11 Data File
If a file has already been extracted and converted from the binary format using the iOS app or
Ocean, it will be stored in a VP2 format. This is a common format that is used across many recent
Valeport products.
From Connect version 1.0.4.0 and Valeport Ocean a slightly altered format: VP2 was introduced to
replace VPD and allow for future expansion. The structure is largely the same.
This format is generated from Connect | Ocean and the iOS App after download and during
recording. The raw downloaded and recorded files are also maintained as a backup.
6.11.1 Basic Structure:
The basic structure is that of an INI file:
The file is split into sections (denoted by a the name of the section in square [ ] brackets).
Within each section, the values are presented as Key Value pairs, delimited by an 'equals' sign.
INI files are fairly old technology, but have been chosen for a number of reasons:
a. They are readily readable as text files.
b. They can be randomly accessed for both read and write - many programming languages
have readily available INI File Access Classes.
c. They are not case sensitive.
d. Their structure can be split into sections, and the sections can be hierarchical by using a
back-slash '\'
e. Comments can be added (prefixing the line with a semicolon ';'
f. They can be readily dropped into Excel etc for onward processing.
