I wish to use this library as well to decode the data (commands) received I am new to tiny gps, and gps receivers and transmitters, but according to this website GPS - NMEA sentence information, the GPGSV messages should have the number of satellites at the 3rd spot. // This demo reads messages from NMEA 2000 bus and // sends them translated to clear text to Serial. U-blox Neo-6m TX to Arduino RX (Software serial pin Welcome to the OpenSkipper project, which provides Open Source C# code for Windows for integrating and displaying NMEA 0183, NMEA 2000 and AIS data from nautical instruments, GPS units and internet data sources. Even more interesting, it uses a series of satellites orbiting the Earth to do so. This should make it possible to decode Is there a NMEA library out there that supports GPRMB? The library by Maarten Lamers is as close as I can find but it doesnt have Routines for the gprmb sentences. It's giving me trouble. To start, we can use any GPS receiver, an Arduino Uno and some male-to-female Jumper cables. My goal is to send the raw NMEA sentences over to the SoftwareSerial port and then pass that data along through my bluetooth module which is connected to the hardware serial port. It contains a NMEA 2000 PGN decoder and can read and write N2K messages. The desired string is the following: A simple and compact NMEA parser for Arduino. I studied the schematic of ST232CN, and i think i made the right connections.
