It communicates with a microcontroller over The module needs an external antenna for any kind of voice or data communications as well as some SIM commands.

To top it off, the module supports quad-band GSM/GPRS network, meaning it works pretty much anywhere in the world.At the heart of the module is A6 GSM cellular chip from Ai-Thinker (Manufacturer of ESP8266 WiFi modules).
You are not reading fast enough from the buffer.The simplest solution to this is to increase the size of the SoftwareSerial buffer from its default size of 64 bytes to On a Windows PC, go to C:\Program Files (x86) -> Arduino -> hardware -> Arduino -> avr -> libraries -> SoftwareSerial (-> src for newer version of Arduino IDE) Open SoftwareSerial.h and change the line:Now let’s program our Arduino to make call. The power supply should also be able to source 2A of surge current, otherwise the module will keep shutting down. Some of them are listed below:The A6 GSM module has total 24 pins that interface it to the outside world. If you wish to send SMS one more time, just hit the RESET key on your Arduino. You got the idea!Before trying the sketch out, you need to enter the phone number. It usually won’t pull that much, but may require around 216mA during phone calls or 80mA during network transmissions. Here are some options you can consider to correctly power your GSM module.One of the cool things about Li-Po batteries is that their voltage is generally in the range of 3.7V – 4.2V, perfect for SIM800L Module. The maximum current draw of the module is around 2A during transmission burst. Do not be tempted to connect this pin to 5V supply on Arduino, as the module will not work due to the lack of supply current. Once the connection is established, we send below AT commands:If your message is long enough just like ours, then you’ll probably receive it with some missing characters. This sketch is very useful when you need to trigger an action when a specific SMS is received. The one uses 1200mAh Li-Po battery and other one uses LM2596 DC-DC buck converter.In case you are using LM2596 buck converter to power up the module, remember to common all the ground in the circuit.Once you have everything hooked up you are ready to go!For sending AT commands and communicating with the SIM800L module, we will use the serial monitor. Your SoftwareSerial receive buffer is getting filled up and discarding characters. Your SoftwareSerial receive buffer is getting filled up and discarding characters. Wiring – Connecting SIM800L GSM module to Arduino UNO. This chart from the datasheet summarizes what you may expect:Since SIM800L module doesn’t come with onboard voltage regulator, an external power supply adjusted to voltage between 3.4V to 4.4V (Ideal 4.1V) is required. Let’s program our Arduino to send an SMS to any phone number you wish. The sketch below will enable the Arduino to communicate with the SIM800L module on serial monitor. Nachdem endlich ein GSM Modul gefunden wurde, wird bereits überlegt, wie man einen HTTP Post Request machen kann. Search for the string ZZxxxxxxxxxx and replace ZZ with county code and xxxxxxxxxx with the 10 digit phone number.The sketch is almost same as earlier except below code snippet. This antenna is very useful for projects that need to save space but struggles in getting connectivity especially if your project is indoors.The second one is any 3dBi GSM antenna along with a U.FL to SMA adapter which can be obtained online for less than $3. 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. You got the idea!Before trying the sketch out, you need to enter the phone number. The operating voltage of the chip is from All the necessary data pins of SIM800L GSM chip are broken out to a 0.1″ pitch headers. Ich möchte hier mal eine Aufstellung der AT Befehle geben, die im Zusammenhang mit GSM Shields auf Basis des SIM900 ICs nützlich sind. To accept/hang a call following AT commands are used:Below output on serial monitor shows call received by A6 GSM module.Copyright © 2020 LastMinuteEngineers.com. The module usually comes with a This module measures only 1 inch² but packs a surprising amount of features into its little frame. So lets get to business!
Interfacing a GSM module to Arduino is pretty simple. Below screenshot shows SMS sent from SIM800L GSM module.Now let’s program our Arduino to read incoming messages.
