I am trying to write a program to read GPS data coming from a balloon payload and use it to point my antennas to stay with the balloon. My problem is I wrote the program assuming the input buffer would contain a whole set of GPS NEMA sentences (GGA, GSA, RMC, etc). But no matter what I do when I read the buffer I only get something like this: 200,W,,,130510,,*09 $GPGGA,123937.095,2831.4487,N,08041.0200,W,0,00,50.0,10.0,M,-31.2,M,0.0,0000*41 $GPGSA,A,3,09,31,2 Which is not a buffer size of 4096 the default. So, I changed the buffer size to 16384. When I was counting on something like this: ,2831.4615,N,08040.9801,W,0.09,108.98,130510,,*1F $GPGGA,124025.092,2831.4615,N,08040.9801,W,1,06,1.0,5.5,M,-31.2,M,0.0,0000*43 $GPGSA,A,3,09,31,22,24,,,,,,,,,6.2,5.4,3.0*39 $GPRMC,124033.092,A,2831.4613,N,08040.9790,W,0.08,168.54,130510,,*1E $GPGGA,124033.092,2831.4613,N,08040.9790,W,1,05,2.0,2.0,M,-31.2,M,0.0,0000*47 $GPGSA,A,3,09,31,22,24,,,,,,,,,6.2,5.4,3.0*39 Can anyone tell me how I can read in more data?? or If it is not possible?? In my Main.Designer.cs file I have: this.serialInput.BaudRate = 1200; this.serialInput.DiscardNull = true; this.serialInput.ReadBufferSize = 16384; I try and read it it like this: // Check if serial port is open if (serialInput.IsOpen) { // Read buffer into a string string inputBuffer = serialInput.ReadExisting(); ... Using Microsoft Visual C# 2008 Express Edition Thanks
