Can someone help me? I'm using a sim7000e from Waveshare. One week ago it was working normally, but now it doesn't work at all; it even can't read the RX-TX communication.
#include <SoftwareSerial.h> //koneksi ke modem #define TINY_GSM_MODEM_SIM7000 #define TINY_GSM_DEBUG SerialMon #define BAUD 9600 #define SerialMon Serial const byte rxpin = 2; const byte txpin = 3; SoftwareSerial SerialAT(rxpin, txpin); // RX, TX
That's my code for connecting to the Arduino. I believe it from my Arduino, but I don't know if something wrong from Arduino.
My 5V (sim7000E) to 5V (arduino mega2560), GND to GND.
Because I'm using Putty on USB for reading my AT-cmd it doesn't and has some trouble.
