AT commands via Ubuntu terminal
- After connecting the modem to your computer, we scan all connected devices. We see four USB devices, one of which will be for AT commands (usually USB2 or USB3).
- Now connect via minicom (USB2 in this case):
- After successful login, enter the following commands:
1. First enter the ATE1 command to enable local echo (to see the output like “OK” to any command).
2. Enable SMS text mode with AT+CMGF. The command specifies the input and output format of the short messages. In this case enter AT+CMGF=1.
3. Issue AT+CMGS=”<phone number>” to enter SMS text input prompt mode. After invoking the write command, wait for the prompt “>” In the text area type the SMS text. When finished – hit Ctrl+Z to send the SMS. Once Ctrl+Z is hit and SMS is sent – you shall see your text and “+CMGS: “ code that denotes how many symbols were sent.
