hey im working on a gps project also. I'm using the
#include <TinyGPSPlus.h> library.
full example - I get my data however when i try to pull serial data over blue tooth from my phone i only get one stream of serial, perhaps its the both serials running at same time. Admittedly im in new territory for my knowledge and training

type or paste code here[code]

Could you take a few moments to Learn How To Use The Forum

It will help you get the best out of the forum in the future.

Thank you.

The Dabble library uses SoftwareSerial and only one instance of SoftwareSerial can be listening for input at a time. Each time you do a Dabble operation that uses SoftwareSerial the GPS will stop receiving input.

This may provide a workaround. It waits for a complete message from the GPS. It will hang your sketch if the GPS stops sending messages.

void loop() {
  //put your main code here, to run repeatedly:
  Dabble.processInput();

  bool newData = false;
  ss.listen();
  while (!newData)
  {
    if (ss.available())
      newData = gps.encode(ss.read());
  }

Due to their unacceptable behavior, @egghead614 has been permanently suspended from the Arduino forum.

Since there is no point in continuing this discussion, I am locking the topic.
