      Any programmers out here?

      I understand that the A021 communicates by NMEA-0183 (https://en.wikipedia.org/wiki/NMEA_0183) over serial port, and see that the driver has created a virtual COM4.

      Other than “open COM4 and start reading, decoding as per the protocol”, is there any advice? Any existing code libraries that I can use to avoid reinventing the wheel?

      I intend to read the data, push to a server database and code a browser front end (maybe even a Flutter app) to display info.

      Also, the driver is for Windows only. Did anyone find a similar virtual serial port driver for Linux and attach the device to a Raspberry Pi?

        Hi We haven’t check it with Raspberry Pi, but some other customers maybe have something to share with you?

        We know a few customers have get it work.

          Thanks for the reply, seems like “open COM4 and start reading, decoding as per the protocol” is the way to go.

          anyone interested in this, take a look at “Capturing AIS NMEA messages from Quark Elec QK A021 AIS Receiver USB dongle” https://github.com/freerange/ais-on-sdr/wiki/Capturing-AIS-NMEA-messages-from-Quark-Elec-QK-A021-AIS-Receiver-USB-dongle

          And verify your decoding against this online decoder https://www.aggsoft.com/ais-decoder.htm
