We all think of bugging our friends, partners, children for fun or keep a watch on their moves at some point of time.
Using the versatility of the linkit one, we can actually create a compact system, which can SMS us the co-ordinates of the bug on being triggered via a SMS.
Step 1: Connections
The GPS and the GSM modules are built right into the device, so we just need to attach the Wi-Fi and the GSM antennas to the board as show.
Note: The connectors of the antennas are very fragile. Be careful while attaching and detaching the antennas.
Step 2: Code
In my code I used a received SMS to trigger the location information to be passed, but you can even use a delay function to get periodic data.
I have parsed the GPGGA string obtained from the GNSS module so that I get the location in degress with the precision of a double datatype.
This is then sent via SMS which I can directly copy in say google maps and get the exact location instantly
Step 3: Compile and Output
Compile and upload the code to the board.
You don't need the serial monitor. Thus its a completely portable, compact and mobile device.
Bug the person.
I have used the word LOCATE as the trigger, you can change that or use delay as discussed earlier
