Datasheets Lengkap Module SIM800L (Google Drive/Dani)

 Module SIM800L memiliki 12 pin Header,6 di sisi kanan dan 6 disisi kiri,berikut definisi PIN nya
1.NET = Antena
2.VCC = +3.7-4.2V
3.RST = Reset
4.RXD = Rx Data Serial
5.TXD = Tx Data Serial
6.GND = Ground/0V

7.RING  when call incoming
8.DTR
9.MICP = Microphone +
10.MICN = Microphone -
11.SPKP = Speaker +
12.SPKN = Speaker -

Default Boudrate untuk Module SIM800L adalah 9600
Harus Menggunakan Step Down Converter jika akan dihubungkan dengan VCC 5V Arduino

Saya mencoba memberi tegangan VCC SIM800L dengan 4,2VDC (saya turunkan dari 5V vcc Arduino menggunakan Stepdown Buck Converter) dan Hasilnya Muncul Warning Over Voltage pada Serial Monitor.Saya turunkan tegangan sampai 4,15V Warning masih Muncul.

 
Saya turunkan Kembali tegangan VCC SIM sampai 3,7VDC dan baru bisa Berjalan Normal walaupun pada Datasheets nya disebutkan VCC 3.4-4.4VDC

Untuk Koneksi Standar Wiring Module SIM800L dengan Arduino adalah sbb:

Sim800L  <--> Arduino
VCC <--> 3,7V melalui Step Down dari 5V Arduino
GND <--> GND
RXD <--> Tx Serial D1 atau Tx SoftwareSerial
TXD <--> Rx Serial D0 atau Rx SoftwareSerial

Berikut Adalah Coding Untuk Testing Koneksi SIM800L ke Arduino Melalui SoftwareSerial

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

#include <SoftwareSerial.h> SoftwareSerial SIM800L(2, 3); // RX | TX // Connect the SIM800L TX to Arduino pin 2 RX. // Connect the SIM800L RX to Arduino pin 3 TX. char c = ' '; void setup() { // start th serial communication with the host computer Serial.begin(9600); while(!Serial); Serial.println("Arduino with SIM800L is ready"); // start communication with the SIM800L in 9600 SIM800L.begin(9600); Serial.println("SIM800L started at 9600"); delay(1000); Serial.println("Setup Complete! SIM800L is Ready!"); } void loop() { // Keep reading from SIM800 and send to Arduino Serial Monitor if (SIM800L.available()) { c = SIM800L.read(); Serial.write(c);} // Keep reading from Arduino Serial Monitor and send to SIM800L if (Serial.available()) { c = Serial.read(); SIM800L.write(c); } }

#Hubungkan TXD SIM800L ke pin D2 Arduino (Rx SoftSerial) dan RXD SIM800L ke D3 (Tx SoftSerial).Buka Serial Monitor pada Arduino IDE dan Setting Boudrate 9600 - Both NL & CR.

#Pastikan SIM800L sudah dimasukan SIM (microSIM) dan LED Indicator Berkedip Lambat (jika kedipnya Cepat berarti SIM No Signal atau SIM Not Detected)

#Tes Koneksi dengan mengetik at
Kalau koneksi berhasil maka SIM800L akan merespon seperti Gambar di bawah :

Standar ATcommand untuk check parameter SIM800L
AT – is to check if interface is working fine.
AT+CFUN – is used to set phone functionality
AT+CFUN? – returns currently set value for AT+CFUN
AT+CFUN=? – returns all possible values that can be set for AT+CFUN (similar to help)
AT+CFUN=1 – is to sent AT+CFUN to 1 (full functionality)
AT+CREG? – to get network registration information. stat=1 means you are registered with home network
AT+COPS? – returns currently registered operator details
AT+COPS=? – returns all the operators available

Mengirim SMS Sim800L melalui SoftwareSerial tanpa menggunakan Library (hanya AT Command)

 Ketik Huruf "Y" pada Serial Monitor Untuk Mengaktifkan Fitur Caller ID 

 Setelah Fitur Caller ID Aktif maka Nomor Pemanggil akan ditampilkan setiap ada panggilan masuk

Jika Ingin Menyembunyikan Caller ID maka ketik Huruf "T" pada serial Monitor dan Fitur Caller ID akan dinonaktifkan (default) dan Caller ID telefon masuk tidak akan ditampilkan
