How to make phone call send sms with 4G extension - clockworkpi/uConsole GitHub Wiki

First we need power on the 4G extension on the uConsole

Then use AT commands to do the jobs in uConsole

We use /dev/ttyUSB3 as AT port

Check sim card if is ready

echo -en "AT+CPIN?\r\n" | sudo socat - /dev/ttyUSB3,crnl

+CPIN: READY

OK

Check ISP info

echo -en "AT+COPS?\r\n" | sudo socat - /dev/ttyUSB3,crnl

+COPS: 0,0,"SOME-ISP",7

OK

Make phone call

echo -en "ATD123456;\r\n" | sudo socat - /dev/ttyUSB3,crnl

OK

+CLCC: 3,0,2,0,0,"123456",129

replace 123456 with your really target phone number
