About this app

New: Send your locations to Telegram Messenger via maps and messages form! Open your Telegram Messenger app, search for "gps2telebot", select the bot and press START to activate the bot. Send "myid" to the bot to request your Chat ID and when replied by the bot, copy the Chat ID. Open this app (GPS Shield Free V2), go to Settings menu and enter your Chat ID in the "Telegram's [@gps2telebot] Chat ID:" box. Start the GPS and you are ready to go! The app will send your location map and coordinates to your Telegram app at the interval that you set in the Settings menu. Please note that this feature is only an extra function of the app as you can still send the coordinates to the Arduino like before. Refer below instruction for that.

Ever wanted to equip your Arduino project with localization capabilities?

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:

~Latitude*Longitude%Accuracy@Time#

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 nudge.me959@gmail.com.

Note:

This Free version of GPS Shield works just like the Full version, but in time-restricted manner.

You can use all of its function such as GPS coordinate acquisition and serial sending but once the first output string is sent, you only have 3 minutes before the serial output function is disabled.

If you like the function and the practicality of this app, please support me by purchasing the Full version at a very low cost.

Thank you!

New features

* Sending interval is reduced to minimum of 1 second instead of previously 5 seconds.
* Bluetooth listening function added.
* Now the app can work when the screen is off - reduces battery consumption.
* There will be notification service when the app is active - easy to re-access when it is running in background.
* The app does not only send the coordinates to Arduino via Bluetooth, but also send the coordinates to Telegram Messenger in the map and message form.
* Other minor changes.
