•3GPP Rel. 13 Extended coverage
•Control via AT commands according to 3GPP TS27.005, 27.007 and customized AT
commands
•SIM application Tool Kit 3GPP TS 51.01
•SMS
•IPv4/IPv6 stack with TCP and UDP protocol
•OMA Lightweight M2M (LWM2M)

2.2 USB/UART port
configuration
The ME910C1 is provided by 2 asynchronous serial port (CMOS 1.8) and one integrated
universal serial bus (USB 2.0 HS) transceiver with the following composition:
-2 x Telti USB Modem ports
-1 x Telit HS-USB WWAN
-1 x Telit Serial Diagnostic Interface
The screenshot below reports an example of the port composition listed on Windows 10
Device Manager.
USB Modem ports are ACM devices and
can be used as AT Command interface.
Telit HS-USB WWAN is a RMNET adapter
that can be used with Linux
ModemManager and NetworkManager.
On Windows 10 WWAN Adapter should be
automatically loaded as Cellular
Connection in Network & Internet settings
(see image below).
Telit Serial Diagnostic Interface is used for
debug purposes and for firmware upgrade.

4 Check Network
Registration
By default the device perform auto attach and receive an IP from the network.
In this case the active <cid> is 1 and APN will be filled automatically from the network.
If different APN is required an new <cid> should be defined with
AT+CGDCONT=<cid>,APN.
This behaviour can be seen with
Command syntax: AT+CGCONTRDP=
Possible response(s):
+CGSCONTRDP:<cid>,<p_cid>,<bearer_id>[<CR><LF>
+CGSCONTRDP: <cid>, <p_cid>,<bearer_id> […]]
Example:
AT+CGCONTRDP=
+CGCONTRDP:
1,5,"lte.tim.it.mnc001.mcc222.gprs","10.0.105.40.255.0.0.0","10.0.105.41","213.230.130.222"
,"213.230.130.222","0.0.0.0","0.0.0.0"
OK
Command syntax:: AT+CGPADDR=
+CGPADDR: <cid>,<PDP_addr>[<CR><LF>+CGPADDR: <cid>,
<PDP_addr>[…]]
Example
AT+CGPADDR=
+CGPADDR: 1,"10.0.105.40"
+CGPADDR: 2,""
OK
This APN lte.tim.it.xxx has been set by the network.
If you need to use a different APN you can set it with the command described before

11 of 23
Reproduction forbidden without Telit Communications PLC written authorization – All Rights Reserved
AT+CGDCONT=1,ibox.tim.it
In order to activate this new APN you need to send AT+CGATT=0
and after AT+CGATT=1, that means detach and attach to the network.
4.1 Registration AT script example
Without setting APN
AT+CGCONTRDP=
+CGCONTRDP:
1,5,"lte.tim.it.mnc001.mcc222.gprs","10.0.105.40.255.0.0.0","10.0.105.41","213.230.130.222"
,"213.230.130.222","0.0.0.0","0.0.0.0"
OK
AT+CGPADDR=
+CGPADDR: 1,"10.0.105.40"
+CGPADDR: 2,""
OK
After setting the new APN
AT+CGDCONT=1,"IP",ibox.tim.it
OK
AT+CGATT=0
OK
AT+CGATT=1
OK
AT+CGCONTRDP=
+CGCONTRDP:
1,5,"ibox.tim.it.mnc001.mcc222.gprs","10.69.26.6.255.0.0.0","10.69.26.7","213.230.134.107",

OK
AT+CGPADDR=
+CGPADDR: 1,"10.69.26.6"
+CGPADDR: 2,""
OK
You can also check the registration with:
AT+CEREG?
+CEREG: 0,1

4.2 Network selection
AT#WS46 is the command that allows to set access technology on the module. Description
of the command here below:
AT#WS46=<n> set command selects the IoT technology to operate with.
Parameter:
<n> - integer type, it is the technology to be used:
0 – CAT-M1
1 – NB-IoT
2 – CAT-M1 and NB-IoT
The parameter is stored in NVM and the settings is available at next reboot.
If AT#WS46=2 (CAT M1 and NB IoT) the module starts to search for CAT M1 networks first,
if it doesn't find any it starts searching for NB IoT networks.

5 Check/Set data service
When registration has been executed you can activate the context with the AT#SGACT
command:
AT#SGACT=<cid>,<status>
e.g. if we want to activate context 1, AT#SGACT=1,1
in case we want to use the <cid> 3 (e.g. Verizon in US) AT#SGACT=3,1.
See in the next paragraph a full example.
