SIM808 GPS / GSM Locator with Arduino

Hi guys, this is my simulation of the SIM808 GPS / GSM Module with Arduino.
Thanks to alselectro for his awesome tutorial about sim808 www.google.com...
As for the module that I used in this video, it is actually part of a school project of my friend (Tom de los Santos ) :) to be incorporated in a mobile solar power tracking system that will also report the battery charge level status and location of the solar panel. Well that's his problem statement that was required by his professor.
If you need codes, you can just email me at [e-mail] or message me on my fb messenger gabs1216 . Enjoy!
Reference AT Commands:
AT+CMGF=1 -configure SIM to TEXT mode
AT+CGNSPWR=1 -Turn on GPS(GNSS - Global Navigation Satellite System)
AT+CGNSSEQ=RMC -configure GPS settings
AT+CGPSSTATUS? - check if GPS fix is already available (should be either 2d or 3d fixed location)
AT+CGNSINF - get the GPS location
AT+CMGS="phone number" -Send message. Followed by the message. Terminated/ended by a special symbol from Notepad++ (combination of ALT+026) "SUB" symbol.
Also refer to my other video regarding some useful AT commands:
• Some SIM808 AT Command...
Also refer to my sample simulation of vehicle GPS tracker using the same concept:
• Mobile Phone Triggered...

Hello sir, can i ask why it shows "gps initializing..." on my serial monitor? I followed the code on your reference. Can you help me?

[@gabs1216]

Here are the things to check :
1. Make sure that you use 12v 2Amp or 1Amp power supply for the barrel jack.
2. Double check the wiring using a multimeter. Or you can verify by replacing the jumper wires with a new one

[@fahetchuisseueric2191]

please i don't know why but my sim808 module gives me inaccurate positions by far

[@gabs1216]

Hello, make sure you have positioned the antenna with the top mark "GPS" facing the sky and/or near the window.. You can test the GPS status by entering the AT command : AT+CGPSSTATUS? In the serial monitor. And then the expected result should be either 2D or 3D fix location

[@pilot668]

my gps led is not blinking. its taking time to connect what might be the issue?

[@gabs1216]

Try checking the following :12v 1Amp supply, GPS antenna connection, arduino wiring, antenna location must be near or outside the window

@@gabs1216 yes it's [e-mail] it would be really helpful

[@gabs1216]

Assuming you have the same module as mine, enter the following AT commands:
AT+CGNSPWR=1 this will power up your GPS. But ensure that you already pressed the small power button for about 2 seconds on the module.
Then AT+CGNSSEQ=RMC this will configure the GPS sentence to be returned.
Then AT+CGPSSTATUS? This will determine the GPS status. Ideal result should either be 2d or 3d fixed location.
Then AT+CGNSINF this will retrieve the GPS NMEA sentence.. Let me know how it goes
I'll send you the code when got home

Sir how to fix the inaccurate gps location in gsm gps sim808 shield

[@gabs1216]

place your antenna such that it is facing up the sky. if you are located inside the house, make sure that your antenna is near the window

[@gabs1216]

It does not necessarily need an internet to obtain a GPS location.. You only need to make sure that the antenna is facing the sky. It will usually take few minutes or even longer on the first time to get a fixed 2d or 3d location when you place an at command AT+CGPSSTATUS?
Once you got a fixed location, it simplY means that the GPS satellite has got your module located

Make sure you have the done the following on your setup:

2. Connection must be wired such that the sim808 TX is connected to arduino RX, while sim808 RX is connected to arduino TX and both grounds are also connected.
