AIS over WiFi with the DT-06 WiFi module
The auxiliary serial port is pin-compatible with the inexpensive DT-06 WiFi module. With the module,
dAISy 2+ can make data available wirelessly to mobile devices like laptops, tablets and smartphones.
What you need
-DT-06 WiFi module, available for US$4 to $10 on Ebay and other online shops.
-An app that accepts AIS from a network connection, like for example OpenCPN, Navionics,
BoatBeacon or SailGrib. In this document, we will use OpenCPN, but configuration of other apps
is very similar.
WARNING: We received reports that some DT-06 modules offered on Ebay and AliExpress don’t
work. We buy our modules from these two vendors:
szdoit on AliExpress: https://www.aliexpress.com/item/32813585141.html
Geekcreit on BangGood: https://www.banggood.com/DT-06-Wireless-WiFi-Serial-Port-Transparent-

Installing the WiFi module
Remove power from the dAISy AIS receiver before installing the
module.
Plug the WiFi module into AUX Serial so that the VCC and GND pins of
the WiFi module line up with the respective labels on dAISy. With that,
dAISy TXD will be connected to WiFi RXD, and dAISy RXD to WiFi TXD.
The module may be upside down compared to the picture, that’s ok if
the pins are connected as described above.
Connect dAISy to power. The LED on the WiFi module should light up.
At any time, the module can be reset to factory default settings by keeping the button labelled G
pressed until the LED turns off.
Configuring the WiFi module
When first powered up, the module will show up as a WiFi access point with the name Doit_WiFi_x,
where xare the last 6 characters of the module’s MAC address.
Connect to this access point with a computer or mobile device. Open a browser and in the address bar
type http://192.168.4.1 and press enter. You will see the configuration menu of the WiFi module.
First, configure the communication between the WiFi
module and dAISy.
Navigate to MODULE > Serial. Set BaudRate to 38400.
Leave the remaining fields at their defaults (8, NONE, 1,
50).
Click Save.
Next, configure protocol, address, and port on which AIS
data will be broadcasted.
Navigate to MODULE > Networks. In the field Socket
Type at the top of the page, select UDP Broadcast from
the drop down.
Further down the page, in the fields below the blue
section title UDP Broadcast, enter the IP address
192.168.4.255 and the port number 9000.
Click Save.
Write down the IP address and the port number on a
piece of paper. You will need them for the configuration
of the navigation apps on PCs and mobile devices.
We recommend protecting access to the WiFi module by
setting a password.
Navigate to MODULE > WiFi. In the section SOFT AP
Settings enter the desired password into the field
Password. The password must be 8-63 characters.
Optionally, you can change the name of the WiFi module
by updating the field SSID Name.
Leave the other fields unchanged.
Scroll to the bottom of the page and click Save.
If you ever forget the password, you can reset the WiFi
module to factory configuration by keeping the button
labelled G pressed until the LED turns off.
To activate the settings the module needs to be restarted. Navigate to MORE > Restart. The settings
you’ve made are now active.
Configure OpenCPN
Applications that process the AIS data must be configured to receive data from the UDP with the IP
address and port you noted down. Here we use OpenCPN, but the procedure will be similar with other
applications.
Connect your computer or mobile device to the WiFi access point of the dAISy 2+ AIS receiver.
Start OpenCPN. Go to Options > Connections. Click Add Connection to create a new connection. Select
the Network radio button, and under Protocol select UDP. In the field Address, enter the IP address you
noted down. In the field DataPort enter the port you noted down.
Optionally, you can give the connection a name by entering the desired name in the field User
Comment.
Leave the remaining fields at their defaults. Press OK to save and activate the new connection. If there
are AIS targets in range, OpenCPN will now start receiving AIS data.
Configure Navionics Boating App
Garmin Boating, also known as Navionics, is a popular
app for mobile devices that in its paid version also
supports AIS.
Connect your mobile device to the WiFi access point
of the dAISy 2+ AIS receiver.
Open the Navionics app. Go to Menu > Paired
Devices. Press +to connect a new device, and press
ADD DEVICE at the bottom of the screen. Give the
device a name, for example dAISy. In the field Host
enter the IP address you noted down. In the field Port
Number enter the port you noted down. Press UDP to
select the correct protocol.
Press Save to complete the configuration.
Note that Navionics will report the AIS receiver as
Disconnected if there is no active AIS traffic.
