GPS data over Bluetooth from Arduino to Android

Development Boards Arduino
1

Hello,

I have a larger project I am trying to complete that I need some assistance with.

I know am going to need some model of an arduino, a gps, and a Bluetooth module.

What I need to do is have an arduino connects to a gps, parse the data from the gps to get the lat, long, course, altitude.

Then those will be sent via bluetooth from the arduino to an Android phone to do some other things.

The main questions are:

  1. Which arduino to use (Uno or the new IOIO board)

  2. Which GPS?

  3. Can you use bluetooth and gps at the same time easily?

  4. Anyone have any links/tutorials on using Bluetooth from Android to get data from an arduino?

Thanks

Potentially, with IOIO you’d have the following advantages:

  • No need to write any firmware, just Java (assuming the GPS works with one of the supported protocols, e.g. UART, SPI, I2C)

  • Smaller size.

  • Cheaper (IOIO+BT dongle compared to UNO + serial BT module)

  • Possible to connect over USB.

  • Easier wiring and no configuration of the BT module.

I was going to get an IOIO anyway! :slight_smile:

Now I just need an accurate gps that works. As well as some help in how you would attach it.

Size is key for my application too.

Ok but the question is

Bluetooth will require Tx and Rx pin of arduino

gps will require Tx and Rx pin of arduino

in arduino Uno there is only two pins , is it possible to connect Bluetooth smirf RN-42 and EM-406A SiRF III to that same 2 pins Rx and Tx of Arduino uno

You can create multiple instances of SofwareSerial to use different devices on different pins.

There are GPS keyfobs that can send bluetooth directly, no need for the Arduino if the android can receive BT.
