  • Page 8 #: Save current settings (serial, AIS channel, and debug) as power-on defaults. This is particularly useful when you want to persist the settings for the NMEA and auxiliary serial output. ESC: Resume receiving AIS messages. 3.2.2 Debug options D: Toggles debug messages. When enabled and in AIS receive mode, signal strength and other information about valid and invalid AIS packets will be displayed.

    5 Using the Auxiliary Serial connector For tinkerers, dAISy 2+ provides an auxiliary serial port on the rear of the unit. This connector can be used to process AIS messages with other devices. The pinout of the serial connector is compatible with HC-05/HC-06 Bluetooth modules and DT-06 WiFi modules widely available on eBay.

    5.1 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. 5.1.1 What you need DT-06 WiFi module, available for US$4 to $10 on Ebay and other online shops.
  • Page 12 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.
  • Page 13 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.

  • Page 15: Tips For Good Ais Reception

    6 Tips for good AIS reception Due to their low-cost architecture, dAISy AIS receivers are not as sensitive as some higher priced receivers. The following basic measures can be taken to improve performance. 6.1 Antenna If everything else is optimal, almost any antenna tuned to the VHF band will work. We used a simple wire cut to length for my first prototypes.

  • Page 16: Radio Frequency Noise

    6.3 Radio frequency noise The main weakness of the dAISy AIS receivers, and probably most low-cost and SDR-based AIS receivers, is susceptibility to out-of-band RF noise. The effect of noise is reduced range, and fewer successfully received packets. Unfortunately, there’s not much we can do except finding a spot that’s less impacted by noise.
