I have looked for something that might solve this on the internet for many weeks but I can't seem to exactly pinpoint what the problem is.
I am trying to make a trackable probe that can send me raw NMEA sentences through the serial port of the Arduino so that a GPS parsing program called Goops can process them and display the position in real time of the probe on Google Earth. When I use pins 0 & 1, and a Serial.read() etc... function the NMEA sentences display correctly and Goops is able to read them and thus display the position of my probe in Google Earth. I am not using tinyGPS because I want the raw information to be sent through the serial, not process it in the Arduino.
The problem is that I have a wireless modem connected to the pins 0 & 1 to be able to see messages from the Arduino, for instance when I activate certain sensors remotely such a camera or a heater by sending a command and making the program read the values passing through the Serial then checking for a specific combination, a println() command displays a message of confirmation of something happening.
Both things work separately, but when I put them together, the GPS NMEA sentences are displayed, but for some reason they become corrupted and Goops does a checksum and they always fail, so I never get any GPS positioning, the other things work well though. But I really need the GPS otherwise I am in trouble! XD
I am using SoftSerial to make the serial input of the GPS, I am using different Baud rates for the pins 0 & 1, 115200 which do not use SoftSerial but the other pins for the GPS do and they have a different baud rate, 57600, to be precise.
What is it? I am thinking that I am not using SoftSerial correctly, or maybe it cannot handle such things? But I don't think so as it works with TinyGPS and the example they give us.
Here is my code (I surely have many mistakes, it is my first complex program, and I am using an example in the Arduino Playground for the GPS as TinyGPS was not accomplishing what I wanted) :
Thank you for your time! I am new to the community and open source Arduino I am loving it!
