11 AT command and usage examples
11.1 Checking the SIM presence
1. Enable the extended error codes to get a verbose format:
AT+CMEE=2
OK
2. Now get the status of SIM presence:
AT+CPIN?
+CME ERROR: SIM not inserted
Above AT command response indicates that SIM card is not present.
3. Verify that SIM is inserted properly and check again:
AT+CPIN?
+CPIN: READY
OK
When the SIM card is ready, above AT response will be received from the module.
1.10.2 SIM PIN Status
1. Get the status of SIM PIN:
AT+CPIN?
Portname = "/dev/ttyUSB0";
serial_port = open(portname, O_RDWR);
// Check for errors
if (serial_port < 0) {
fprintf(stderr, "Could not open %s: %s\n", portname, strerror(errno));
exit(EXIT_FAILURE);
}
// Create new termios struc, we call it 'tty' for convention
struct termios tty;
memset(&tty, 0, sizeof tty);
// Read in existing settings, and handle any error
if (tcgetattr(serial_port, &tty) != 0) {
fprintf(stderr, "Error %i from tcgetattr: %s\n", errno, strerror(errno));
fprintf(stderr, "Could not get options for modem connection%s\n", portname);
exit(EXIT_FAILURE);
}
tty.c_cflag &= ~PARENB; // Clear parity bit, disabling parity

11.2 Sending SMS
Preparing the device
Activate SMS text mode using the following command:
AT+CMGF=1
In text mode there are some additional parameters that can be set.
Using the following command, we can read the current values:
AT+CSMP?
The device will respond with a string like this:
> +CSMP: 1,169,0,0
> OK
The first value is a combination of some option bits:
Bit 7
RP
Reply path, not used in text mode
Bit 6
UDHI
User Data Header Information
Bit 5
SRR
Set this bit to request a delivery report
Bit 3,4
VPF

Page 13
Bit 0 of the message is always set when sending messages (SMS-SUBMIT). So, the first value should
be 1 or higher. The second parameter sets the Validity Period of the message. This value is encoded
as follows:
0 - 143
(VP + 1) x 5 minutes
144 - 167
12 Hours + ((VP-143) x 30 minutes)
168 - 196
(VP-166) x 1 day
197 - 255
(VP-192) x 1 week
The third parameter contains the PID (Protocol Identifier). This parameter is only used for advanced
messaging. The fourth parameter contains the DCS (Data Coding Scheme). This parameter is used to
select the character set/message type. When setting the DCS parameter to '0' standard 7-bit text is
sent. When setting this parameter to '16' the message is sent as a flash message.
To send a message with a validity period of 1 day, the parameters have to be set like this:
Bit 0 and 4 of the first field has to be set, so the first value will become 1 + 16 = 17.
Send the following command to the modem to set these parameters:
AT+CSMP=17,167,0,16
If the modem responds with "OK", the modem is ready to send (flash) text messages with a validity
period of 1 day.
Sending an SMS message
To send the SMS message
AT+CMGS="+4917604069083"
Replace the above phone number with the wanted phone number. The device will respond with:
>
Type the message text and send the message using the <CTRL>-<Z> key combination:
> Test! <CTRL-Z>
<wait until the message has been processed>
> +CMGS: 62 Message was sent correctly
Sending a Unicode SMS message
To check whether your device supports this mode, just type the following command:
AT+CSCS=?
This command displays the code pages supported by the device. The device will respond like this:
+CSCS: ("IRA","GSM","UCS2")

If this string contains "HEX" or "UCS2", Unicode seems to be supported. To specify that you will use a
UCS2 string to send the message, set the codepage to "UCS2" depending on the device response. In
our example we will set the device to "UCS2":
AT+CSCS="UCS2"
Next, specify the correct DCS (Data Coding Scheme) for Unicode messages, which is 0x08. Set this
value by changing the fourth parameter of the AT+CSMP command to '8':
AT+CSMP=1,167,0,8
The device is now ready to send messages as Unicode.
11.3 GNSS (localization)
Turning GNSS on and off
Turn on GNSS function:
AT+QGPS=1

11.4 Setting WWAN Priority Mode
MC93 features ultra-low power consumption by supporting Extended Discontinuous Reception
(eDRX), a feature in NB-Iot and LTE M that enables developers to set, and later change how long a
device stays in low-power sleep mode before it wakes up to listen for any network indications for
pending data, thus reducing the power consumption.
To minimalize the power consumption, GNSS and WWAN cannot work simultaneously, either
WWAN or GNSS takes priority during implementation. By default, the modules are configured into
the GNSS priority mode, which can be switched to the WWAN priority mode.
Enable WWAN Priority Mode:
AT+QGPSCFG="priority",1,1
Enable GNSS Priority Mode:
AT+QGPSCFG="priority",0,1
Paging Time Window Value and eDRX Setting
Depending on the values given by your SIM Card provider, you can set the TPTW and eDRX value to
allow the change between WWAN and GNSS modes in WWAN priority mode.
Note that the switch between WWAN and GNSS may not work if the TPTW and eDRX values are not
supported by the mobile provider.
To set the values the command AT+QPTWEDRXS is used.
