2 .Introduction to data link of depth sounder
D270 sounder interacts with external devices in three ways: wifi, Bluetooth, serial
port;
Bluetooth：The sounder receives GPGGA and other position data of RTK through
Bluetooth connection；
WIFI：: The laptop can access the web page of the sounding instrument through
wifi connection to view real-time waveform, set sounding parameters and set data
recording;It can also be connected via wifi, using Hydrosurvey for bathymetry control
