Introduction
SIM808 GPS/GPRS/GSM arduino shield (https://www.dfrobot.com/product1469.html) is an integrated quadband GSM/GPRS and GPS navigation technology
Arduino expansion shields. A credit card size only, according to the standard Arduino pin packaging, compatible with Arduino UNO
(https://www.dfrobot.com/product1468.html), arduino Leonardo (https://www.dfrobot.com/product698.html), arduino Mega (https://www.dfrobot.com/product
358.html) and other arduino mainboard (https://www.dfrobot.com/category104.html).
Compared to the previous generation SIM908, SIM808 made some improvement on the performance and stability. In addition to the normal SMS and phone
functions, the shield also supports MMS, DTMF, FTP and other functions. You can achieve the data acquisition, wireless data transceiver, IoT application and GPS
orientating. The should integrates onboard microphone and headphone jack, saving your cost and making your project easily. it can also directly connect to the
GSM and GPS antenna by an external antenna connector.
SIM808 GPS/GPRS/GSM Arduino Shield V1.0 uses the latest version of Simcom SIM808 module, compared with the early SIM808 module available in the market,
the new module has better stability. But GPS part of AT commands are not compatible with the old version of the SIM808 module, please refer to the bottom of the
"more" in the AT commands.

(/wiki/index.php/File:TEL0097_TCP.png) TCP communication GPS Orientation Note: The GPS antenna must be placed outside before it can obtain a stable GPS location data output. Send AT + CGSN PWR = 1 command (Open the GPS power) Send AT + CGNSTST = 1 command (Receive GPS data from the serial port) (/wiki/index.php/File:TEL0097_GPS_debug.jpg) GPS_debug If the GPS antenna has been placed outside, you should get the right data soon. When you want to pause GPS data output, you can sent AT + CGNSTST = 0 command to pause GPS data output. When you want to turn off GPS function, you can send AT + CGNSPWR = 0 command to turn off the GPS power. Send AT + CPOWD = 1 to shut down the SIM808 chip. More exciting instruction, please refer to AT command on the page of the end. These two test code are very simple, and easy to be understood. Only need to enter the corresponding serial AT commands, you would achieve the corresponding functions. SIM808 Low Power Consumption Mode Minimum Functionality Mode The system will be reduced to a simplest mode under Minimum Functionality Mode. It will save more power consumption in this mode. AT+CFUN=<fun> <fun>=0,1,4 AT + CFUN = 0: Minimum functionality mode. In this mode, you can still continue to use the serial port, but the AT command with RF and SIM card features will be disable. AT + CFUN = 1: Fullfunction mode (default). AT + CFUN = 4: Airplane mode. In this mode, you can still continue to use the serial port, but the AT command with RF and SIM card features will be disable. More features please refer to AT commands Instructions... -
