3. SIM808 V2 2 5 user manual V1 2 Electrodragon com time Descriptions version Getting Started A little preparation goes a long way so make sure you ve covered the following points Regarding your cellular provider Do you have coverage on a GSM 850 MHz GSM 900 MHz DCS 1800 MHz or PCS 1900 MHz network When we say GSM that means 2G not 3G 4G or LTE Will they allow the use of non supported devices on the network Some carriers will block IMEI numbers that were not provided by their sales channel Or you may have to call the provider and supply the IMEI of your GSM module to allow it on the network Finally it would be wise to use either a prepaid or an account that offers unlimited SMS text messaging you don t want any large bills if things go wrong Power Do you have adequate power for your SIM808 module Some shields will use more current up to 2A so you may need an external high current supply We needs 5V up to 2A or 9V 1A or 12V 1A into the onboard socket Otherwise check with your supplier Antenna If your module shield etc doesn t have an antenna get one You do need it Insert the SIMCARD correctly And as always please don t make an auto dialer Furthermore get the SIM800 Series AT Command Manual V1 07 pdf and the SIM808 Hardware Design V1 00 pdf as we ll refer to those throughout the tutorial e Power There is a DC socket on the shield which is for a 5V power supply The power pins are 5V and GND
4. The SIMCOM hardware manual for the module notes that it can draw up to 2A for short bursts So get yourself a 5V 2A power supply and connect it via the DC socket gt e S IM808 TTL Serial This shield has a set a TTL UART serial which is capable with 5v system by default When you want use a 3 3v or 2 85v system to control it you should remove the OR from the 5V side to the 2 85V side Wow all those rules and warnings The sections above may sound a little authoritarian however we want your project to be a success Now let s get started A quick test At this point we ll check to make sure your shield and locate and connect to the cellular network So make sure your SIM card is active with your cellular provider When you insert the SIMCARD please refer the schematic diagram next to the SIMCARD socket 20 ICE Then connect the USB TTL module to the TTL UART The hardware connection between the USB TTL and SIM808 module is like this USB TTL SIM808 CS CE CS mo Then connect the 5V power to the DC socked on the GSM shield and then watch the following three LEDs The bright STA LED will come on and then the NET LED will blink once every 800 milliseconds until the GSM module has found the network at which point it will blink once every three seconds The PPS LED is used to indicate the GPS is fixed or not But the GPS function is closed by default so there will be nothing until we do somethin
5. g to the GPS function We will do some introduction next Nothing can happen until that magic three second blink so if that doesn t appear after a minute something is wrong Check your shield has the appropriate power supply the GSM antenna is connected correctly the SIM card is seated properly and locked in and that your cellular account is in order Finally you may not have reception in that particular area so check using a phone on the same network or move to a different location We will illustrate the usage of the module with an example of how to operate under GSM mode in the following section We should connect the TTL USB to the GPRS UART interface and press the POWKEY button for 2 second When the four LEDs is lighting it indicates that module is working we can send AT command to control it otart the sscom exe serial tool on PC and perform operations as followed Set Multi Char cow DATA HEX DATA JAT Uv ty 5 e z E 7 oo 20m amp OoIm J Round send interval 1000 yeu SendFile SaveData Clear HexData ComNun COMS CloseCom Help WWW MCU51 COM Hide DIR ATS ESP8266WIF 14E R2077 QOR 120693138 T meme PMP MERE A ARE UFAS v SendNew 7 BIIPCBETIE10 10cn2395077 GHA Data input IRB A http www sz ilc com en COM5 opened 9600bps CTS 0 DSR 0RL_ In this example the ComNum is set to COMB In practical application please right clic
