2.3 USB/UART port
configuration
ME910C1, ME910G1, ML865C1, ML865G1, ME310G1 are equipped with 2 asynchronous
serial port (CMOS 1.8) and one integrated universal serial bus (USB 2.0 HS) transceiver with
the following composition:
•2 Telit USB Modem ports
•1 Telit HS-USB WWAN
•1 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 an RMNET adapter
that can beusedwith LinuxModemManager
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
debugging purposes and for firmware
upgrade.

2.4 Warning on Windows
Cellular connection
When the module is recognized as a Cellular device, Windows uses the WWAN interface to
set up internet connection (NCSI). This could lead to connectivity issues using the module AT
interface: registration to the network, APN management, socket creation and data exchange,
PSM and eDRX functionalities can be affected.
If you do not need your PC is connected via WWAN interface, we strongly suggest to disable
it. Go to:
Control Panel ►Network and Sharing Center ► change Adapter settings ► right-click on
Cellular connection ►disable.

4 Network Registration
Here below a brief overview of 4G (CAT M1, NB IoT) and 2G (GPRS) registration process, IP
stack setup and related commands.
4G registration (CAT-M1, NB-IoT) and IP stack setup: the module performs Attach and EPS
Bearer activation automatically. When the procedure ends an IP address is assigned by the
network to the module. AT+CEREG can be used to check the EPS network registration status.
AT+CGCONTRDP can be used to check the EPS bearer parameters. AT#SGACT command
has to be used to enable the internal IP stack and IPEasy command set.
2G registration and IP stack setup: the module performs GPRS Attach automatically. You can
check the status of registration using AT+CREG and AT+CGREG commands. To get IP
connectivity the user has to activate a PDP context. In this scenario, AT#SGACT command
performs PDP context activation and IP internal stack enabling. After this step, the module has
an IP address and IPEasy command set can be used. AT+CGCONTRDP can be used to check
the PDP context parameters.
To get IP connectivity, for all access technology, a specific APN configuration is required. We
suggest to carefully check with the Network Provider what’s the proper APN configuration to
be used (context ID, APN name). APN configuration can be set through AT+CGDCONT
command.

AT+CREG?
+CREG: 0,1

AT+CGREG?

There’s no need to trigger new registration since the APN will be used in the next step: the
PDP context activation request
AT#SGACT=1,1
#SGACT: 10.34.234.204
OK
The PDP context is active, IP address has been assigned (10.34.234.204) and IP stack is
enabled; now it is possible to perform a socket connection
AT+CGCONTRDP
+CGCONTRDP: 1,5,"internet.wind.biz","10.34.234.204",,"193.70.152.25","212.52.97.25"

OK
AT#SS
#SS: 1,3,10.34.234.204,35911,35.202.235.194,80
…
OK
In all scenarios (2G, CAT-M1, NB-IoT) the command AT+CGDCONT stores APN in NVM, so
the APN setting is needed only once.

4.3 Access technology selection
AT+WS46=[<n>] command selects the cellular netwrok to operate with.
• 4G/2G products support <n> parameter values 12, 28 and 30. 30 is factory default
• 4G only products support <n> parameter value 28
Values [<n>]:
12 : GSM Digital Cellular Systems, GERAN only
28 : E-UTRAN only
30 : GERAN and E-UTRAN
AT#WS46=[<n>] command selects the IoT E-UTRAN technology to operate with.
Values [<n>]:
0 : CAT-M1
1 : NB-IoT
2 : CAT-M1 (preferred) and NB-IoT
3 : CAT-M1 and NB-IoT (preferred)
The parameter is stored in NVM and the settings is available at next reboot.

4.4 Speed up registration
The registration process in CAT-M1 and NB-IoT technologies could require some minutes to
complete. This happens especially in the case of very first registration: new SIM, new location,
new module. This is due to the IoT technology itself and cellular network deployment factors.
To speed up the process you can reduce the set of supported technologies and bands. This
will reduce the radio scanning time of the module. The example below refers to NB-IoT, the
same can be applied to CAT-M1.
1. Check with operator if:
a. the SIM you have is enabled for NB-IoT or CAT-M1; the majority of operators
provides specific SIM for IoT services and technology
b. an APN has to be set for registration/attach and data traffic
2. Turn on the module and set the APN if required, in the majority of cases you'll have to
set it on 1st context: e.g. AT+CGDCONT=1,"IP","NB IoT APN"
3. Set the module for NB IoT only support: AT+WS46=28 , AT#WS46=1
4. Use AT#BND to reduce the set of supported bands. E.g. set support for band 3 and 8
only: AT#BND=0,0,132 (132 decimal ►00101000 binary )
5. Reboot the module to apply the changes above
6. When the module is back on, wait some seconds and run manual registration through
AT+COPS=1,2,"MCCMNC"
7. Poll AT+CEREG? to check the registration status or enable unsolicited indication
through AT+CEREG=2
The same will apply for CAT-M1 using AT#WS46=0.
The reboot is required only once to apply the AT#WS46 setting. Subsequent registrations are
usually faster (e.g. after power cycle): the module store radio link information about previous
registration and use this information to start a new registration.

5 Check/Set data service
When registration is completed you can activate data services and set up the internal IP stack
with the AT#SGACT command:
AT#SGACT=<cid>,<stat>[,<userId>[,<pwd>]]
E.g. if we want to activate context 1, issue AT#SGACT=1,1; in case we want to use the <cid>
3 (e.g. Verizon in US) issue AT#SGACT=3,1.
The command returns IP address provided by the network:
AT#SGACT=1,1
#SGACT: xxx.xxx.xxx.xxx
You can get useful information about the active context using AT+CGCONTRDP command.
AT+CGCONTRDP=[<cid>]
The execution command returns the relevant information on a PDP Context –EPS Bearer
established by the network with the context identifier <cid>. If the parameter <cid> is omitted,
the information for all established contexts is returned. The response message has the
following format.
+CGCONTRDP:<cid>,<bearerId>,<apn>[,<ip&subnet>[,<gw_addr>[,<DNS_prim>
[,<DNS_sec>[, <P_CSCF_prim>[,<P_CSCF_sec>]]]]]][<CR><LF>

6 UDP script
An example of UDP communication over NB-IoT is reported below; in this scenario, APN is
not required and it set automatically by the network. The module enables NB IoT only. A UDP
socket is opened in command mode on xxx.telit.com echo server. “echo_test_UDP” string is
sent to the server and echoed back to the module. Incoming data is signalled through SRING
unsolicited. AT#SI (Socket Info) command is used to check the data buffered and not yet read.
AT#SRECV command is used to read the data. AT#SS command is used to check remote
server IP address and socket status.

An example of TCP communication over NB-IoT is reported below; in this scenario, APN is not
required and it is set automatically by the network. The module enables NB IoT only. A TCP
socket is opened in command mode on xxx.telit.com echo server. “echo_test_TCP” is the data
sent to the server and echoed back to the module. Incoming data is signalled through SRING
unsolicited. AT#SI (Socket Info) command is used to check the data sent and received.
AT#SRECV command is used to read the data. AT#SS command is used to check remote
server IP address and socket status. The module starts with radio off, then radio is switched
on and attach is performed.
