How do I know if SIM800L is working?

If the power to the SIM800L is enough, the on-board LED starts blinking. If it is blinking every second, this means it is searching for a network. You will know if it’s connected to the network when it blinks every three seconds. If the LED blinks very fast, this means it’s connected through GPRS.

How to send/receive text messages from Arduino with sim800l?

The code is really easy first in the “Setup ()” we just send some “AT commands” to make the module on the receiving text mode and set the way those SMS received should be handled. And on the loop there is a classic communication function that permits the communication between the Arduino IDE Serial Monitor and Sim800L “send/receive” between them

How to connect Simsim 800l to Arduino with 5V?

Sim 800L recommended voltage is 3.4V to 4.4V but it can handle up to 5V of Arduino. You can use a linear Voltage regulator like LM317 or LM388 or just use a Buck Converter to step down the voltage. In this tutorial, we won’t be using those and will directly connect our module to 5V. Connect the RX to Digital Pin 2 and TX to Digital Pin 3.

What is the pinout of sim800l GSM module?

SIM800L GSM Module Pinout. The SIM800L module has total 12 pins that interface it to the outside world. The connections are as follows: NET is a pin where you can solder Helical Antenna provided along with the module. VCC supplies power for the module. This can be anywhere from 3.4V to 4.4 volts. Remember connecting it to 5V pin will likely

How do I add an antenna to my sim800l module?

There are two ways you can add an antenna to your SIM800L module. The first one is a Helical GSM antenna which usually comes with the module and solders directly to NET pin on PCB. This antenna is very useful for projects that need to save space but struggles in getting connectivity especially if your project is indoors.
