Hello, In our study, we will send sms to another phone via our SIM card with the Quectel m66 that we have connected to the Arduino Uno card.
Materials We Use
1-Arduino Uno board (whichever you have)
2-Quectel M66 Gsm / Gprs module
For detailed information about the Quectel M66, you can go to the previous location here
Horse commands we will use
AT + CMGF: This command sets the GSM module in SMS Text Mode or SMS PDU Mode.
In Text Mode, SMS messages are displayed as readable text. In PDU Mode, all SMS messages are displayed in binary strings encoded with hexadecimal characters.
Although the Text Mode is easier to use, the PDU Mode is more consistent on different GSM Modems.
AT + CMGS: The phone number to send the message to is the command written.
After sending the code to the arduino board, you will receive sms to the phone number you wrote, if sms has not arrived, it may be one of the reasons below.
If you still haven't received any sms after checking these reasons,
Don't hesitate to contact me
