ULTIMATE EXPLORE All Fuction Module GSM/GPRS SIM800L V.2 with Adafruit_FONA Library

Author : Ila Mulyandi1 comment

Pada Artikel ini saya akan membahas bagaimana mengeksplore atau menggunakan semua fungsi dari Module GSM/GPRS SIM800L dari SIMCOM ini.Tutorial ini dapat digunakan untuk Module SIM800L versi 1 maupun versi 2.


Library Adafruit FONA sendiri sebetulnya di desain untuk module SIMCOM SIM800 dan SIM808 namun karena Chip SIM800L ini adalah versi "Lite" dari SIM800 jadi masih banyak kesamaan dari kedua chip,hanya saja pada SIM800L/800Lite tidak dibekali fitur FM RADIO,BLUETOOTH seperti  apalagi fitur GPS seperti SIM800 dan SIM808.

Sebelum melakukan Explore All Fuction pada SIM800L V.2 (ataupun V.1) mari kita siapkan dulu file dan wiring berikut :

Hardware SIM800L V.2 dapat debeli dengan harga MURAH disini 

1.File Library
Library Adafruit_FONA download disini

Ekstract kemudian masukan kedua library diatas kedalam folder libraries pada folder installer software Arduino IDE (C:\Program Files\Arduino\libraries  atau  C:\Program Files (X86)\Arduino\libraries bagi pengguna Win64 bit) 

2.Wiring
Sambungkan Module SIM800L dengan Arduino (disini saya menggunakan UNO)

SIM800L V.2
5VIN <--> pin 5V Arduino
GND <--> pin GND Arduino 
RXD <--> pin  D2 Arduino
TXD <--> pin  D3 Arduino
RST <--> pin  D4 Arduino 

SIM800L V.1 
VCC <--> 3.7-4.2VDC melalui stepdown dari pin 5V Arduino
GND <--> pin GND Arduino 
RXD <--> pin  D2 Arduino
TXD <--> pin  D3 Arduino
RST <--> pin  D4 Arduino 




2.Sketch Coding
Copy paste sketch dibawah ini ke dalam Arduino IDE kemudian Upload ke dalam Arduino

xxSetelah Upload Sketch diatas Buka Serial Monitor pada Arduino IDE dengan Baudrate 115200 - Newline 

Pastikan anda sudah memasukan SIM Card GSM ke dalam module dan minimal ada pulsanya untuk test kirim SMS dan Telefon.


3.Function & Menu Interface
Berikut adalah Menu yang dapat kita Gunakan untuk Explore fungsi dari Module SIM800L
Beberapa menu yang berhubungan dengan Bluetooth,FM Radio dan GPS tidak dapat kita gunakan jadi tidak usah dicoba,tapi kalau penasaran ya silahkan dicoba aja.


-------------------------------------
[?] Print this menu  --> menampilkan menu perintah ini ke serial monitor
[a] read the ADC 2.8V max (FONA800 & 808) --> membaca tegangan ADC pada Module
[b] read the Battery V and % charged -->membaca Tegangan dan persentase Battery
[C] read the SIM CCID -->membaca SSID dari Sim Card
[U] Unlock SIM with PIN code -->membuka kode PIN dari SIM (apabila status terkunci)
[i] read RSSI -->membaca RSSI SIM (kekuatan signal)
[n] get Network status -->membaca status jaringan
[v] set audio Volume -->mengatur Volume Audio dalam persen 1 - 100
[V] get Volume -->membaca status Volume Audio saat ini
[H] set Headphone audio (FONA800 & 808) -->mengatur Volume audio Headset+Mic port
[e] set External audio (FONA800 & 808) -->mengatur Volume audio Loud Speaker+Builtin MIC
[T] play audio Tone -->Memainkan Audio/Ringtone melalui port Speaker
[P] PWM/Buzzer out (FONA800 & 808) -->memainkan nada/tone (dalam frekuensi/PWM)
[f] tune FM radio (FONA800) -->mengatur frekuensi Radio FM
[F] turn off FM (FONA800) -->Mematikan fungsi Radio FM
[m] set FM volume (FONA800) -->mengatur volume Radio FM dalam level 1-6
[M] get FM volume (FONA800) -->membaca status level Volume Radio FM sekarang
[q] get FM station signal level (FONA800) -->membaca kekuatan signal Radio FM pada freq tertentu
[c] make phone Call --> Membuat panggilan telefon ke nomor lain
[A] get call status --> Membaca status panggilan telefon saat ini
[h] Hang up phone -->Mengangkat panggilan telefon masuk
[p] Pick up phone -->Menutup telefon
[N] Number of SMSs -->Menghitung jumlah SMS dalam SIM Card
[r] Read SMS # -->Membaca SMS pada urutan slot tertentu
[R] Read All SMS -->Membaca semua SMS yang ada di inbox
[d] Delete SMS # -->Menghapus SMS pada urutan slot tertentu
[s] Send SMS -->Mengirim pesan SMS
[u] Send USSD -->Mengirim kode USSD
[y] Enable network time sync (FONA 800 & 808) -->Mengaktifkan Sinkronisasi waktu pada Jaringan
[Y] Enable NTP time sync (GPRS FONA 800 & 808) --> Mengaktifkan Sinkronisasi dg waktu  NTP
[t] Get network time -->Membaca waktu pada jaringan
[G] Enable GPRS -->Mengaktifkan fitur GPRS
[g] Disable GPRS -->Nonaktifkan fitur GPRS
[l] Query GSMLOC (GPRS) 
[w] Read webpage (GPRS) -->Membaca halaman internet
[W] Post to website (GPRS) -->Posting ke halaman internet
[S] create Serial passthru tunnel
-------------------------------------


PASTIKAN SERIAL MONITOR ARDUINO IDE ANDA NAMPAK SEPERTI DIBAWAH INI :
Pastikan Basic Test OK kemudian disusul dengan
+CPIN : READY
Call Ready
SMS Ready

Cara menggunakan Program ini adalah "Anda hanya perlu mengetikan abjad/huruf sesuai perintah
pada menu yang tampil pada serial monitor.

Misalnya untuk membaca SSID anda cukup ketik huruf C pada serial monitor kemudian Enter
Misal untuk mengirim SMS ketik huruf s kemudian akan dilanjutkan dengan instruksi pengetikan nomor tujuan dan isi SMS. 


SELAMAT MENGEKSPLOR MODULE SIM ANDA..
