Hello guys,
i need some help getting my SIM7600G module to work with my Arduino Nano.
Unfortunately, i couldn't find any good tutorials/solutions for my combination.
I installed the Adafruit FONA library and defined the RX (Pin 3) and TX (Pin 2) in the module, as well as plugged in a LTE Simcard.
But the Arduino can't seem to make a connection:

Couldn't find FONA
Can someone help me out? I'm unfortunately not very experienced when it comes to coding.
The code i used is from the library example:
#include "Adafruit_FONA.h"
#define FONA_RST 5
// this is a large buffer for replies
char replybuffer[255];
#include <SoftwareSerial.h>
#define FONA_RX 3
#define FONA_TX 2
SoftwareSerial fonaSS = SoftwareSerial(FONA_TX, FONA_RX);
SoftwareSerial *fonaSerial = &fonaSS;
// Use this for FONA 800 and 808s
//Adafruit_FONA fona = Adafruit_FONA(FONA_RST);
// Use this one for FONA 3G
Adafruit_FONA_3G fona = Adafruit_FONA_3G(FONA_RST);
uint8_t readline(char *buff, uint8_t maxbuff, uint16_t timeout = 0);
uint8_t type;
void setup() {
while (!Serial);
Serial.begin(115200);
Serial.println(F("FONA basic test"));
Serial.println(F("Initializing....(May take 3 seconds)"));
fonaSerial->begin(115200);
if (!fona.begin(*fonaSerial)) {
Serial.println(F("Couldn't find FONA"));
while (1);
}
type = fona.type();
Serial.println(F("FONA is OK"));
Serial.print(F("Found "));
switch (type) {
case FONA800L:
Serial.println(F("FONA 800L")); break;
case FONA800H:
Serial.println(F("FONA 800H")); break;
case FONA808_V1:
Serial.println(F("FONA 808 (v1)")); break;
case FONA808_V2:
Serial.println(F("FONA 808 (v2)")); break;
case FONA3G_A:
Serial.println(F("FONA 3G (American)")); break;
case FONA3G_E:
Serial.println(F("FONA 3G (European)")); break;
default:
Serial.println(F("???")); break;
}
// Print module IMEI number.
char imei[16] = {0}; // MUST use a 16 character buffer for IMEI!
uint8_t imeiLen = fona.getIMEI(imei);
if (imeiLen > 0) {
Serial.print("Module IMEI: "); Serial.println(imei);
}
The module i use:

Thank you!
