May be you are designing a self locating robot or vehicle auto tracking system, but you are in trouble with real GPS module/shield.
Perhaps the cost of the GPS hardware is out of your budget or its output format is simply hard to understand/decode.
Turn your phone into a GPS Shield!
This app provides you a GPS solution by acquiring the GPS signal and outputs the obtained coordinates through a string format via Bluetooth connection.
The output string can be sent to your Arduino board through Bluetooth connection and can be used to locate the current location of your project.
All you have to do is just connect a Bluetooth module (such as HC-06) to your Arduino board, upload the appropriate GPS string parser (sample is available) and establish Bluetooth connection between your project and this app.
You can view the sent output strings in real time by using the Arduino IDE's Serial Monitor window which consist of latitude, longitude, accuracy and time separated by modifiable serial headers.
Or else just use my Bluetooth Serial Terminal or Bluetooth Serial Monitor app to view the output in handy and mobile way!
Using my Bluetooth Serial Terminal/Monitor app, you can view how the GPS Shield app functions right away in seconds without the need of Arduino board/Blueeoth module at all.
The interval of each output string sending can be set through Settings menu which the minimum value is 5 seconds.
The output string format is:
The output format is tailored to be easily read by everyone (including Arduino of course).
For example: ~3.1276*103.8624%6.2@173405#
The decimal places for latitude, longitude and accuracy can be set to any value you like (through Settings menu) and the format for time is as "HHmmss".
You can change the serial headers to any character you prefer such as from "~" to "A", "*" to "T" and so on, but make sure you make change in the Arduino's serial parser code as well.
If you need the Arduino serial parser code to decode the output string of this app, please don't hesitate to email me at firstname.lastname@example.org.
Update: Now you can send the coordinates along some information of your location to Telegram app. Open your Telegram Messenger app, search for "gps2telebot" then Click "START" after selecting the bot. Request your Chat ID from the bot by typing "/myid" and use the Chat ID in this GPS Shield Pro app to receive your current location. Any question please ask me through email.
