1.2 Product Overview
The Skywire™ Development Kit includes one baseboard, antenna, power supply, SIM cards, and
debug cables. Skywire modems must be purchased separately. The kit enables you to develop
your application directly on the Skywire™ modem with three different ways to connect:
Connect your PC to the xE910 modem UART port via onboard USB-to-UART converter
and send AT commands directly to the modem through PC terminal applications. You
can also connect over USB for access to multiple COM ports.
The kit is an Arduino shield, so you can plug the kit directly onto an Arduino
microcontroller. Please see Section 3: Common Next Steps for links to example
documentation.
To connect the kit to a different processor or development kit, a 14-pin header breaks out
the necessary signals for easy connection to any device. The modem supports I/O levels
from 1.65-5.5V, simplifying connection to other systems.

2. Connect to Kit using a PC
This section covers how to connect your development kit to a PC and
provision the modem with your cellular plan. It also covers how to
communicate over the serial port to the Telit x910 modem which only
requires the use of USB port and connector marked J14 or USB2 in the
diagram below. USB1 (connector J5) is used for Telit firmware updates to
the modem and is not used in this section.

2.2 Skywire™ Placement
To mount your Skywire™ Cellular modem follow these steps:
1. Gather the following:
a. Skywire™ Development Kit board
b. Skywire™ Cellular Modem
c. U.FL extractor tool (Always use a U.FL extractor tool when placing or
removing U.FL cables on the Skywire™ modem to avoid damaging the
U.FL connectors).
2. Line up your Skywire’s™ cellular U.FL connector(s) on the side of the board
closest to the antenna connector. Depending on the type of Skywire™ Modem
you have there may be one, two, or three U.FL connections.
3. To avoid damage to the U.FL connector and maximize connector life, a U.FL
removal tool should be used when attaching/removing the U.FL connector.
Always insert and remove the U.FL connector with a force perpendicular to the
board. If your Skywire™ is using GPS, attach the GPS antenna to the bottom of
the Skywire™ connector X3. If you are not using your Skywire’s™ GPS or if your
Skywire™ does not support GPS, continue to step 4.
4. Attach the U.FL cable to the top U.FL connector X1 on the Skywire™. If you are
using a Skywire™ with the cellular diversity antenna option attach a second
antenna to connector X2.
5. Carefully seat your Skywire™ into the board’s Skywire™ socket (U1). Take care
to ensure that the pins are correctly aligned. Failure to properly align the pins
may damage your Skywire™.
A common issue is accidentally inserting the modem with pins
misaligned by one row. Check pin alignment BEFORE applying
power to prevent modem damage.

2.11Activate Modem (one-time step)
If you are using a new SkywireTM cellular module, it does not
have an active cellular plan. To activate a Verizon data plan,
send an email to [e-mail] with the
following information:
- Name
- Contact Phone Number
- For NL-SW-1xRTT-V and NL-SW-EVDO-V Modems:
MEIDs of all the modems you would like to activate
- For NL-SW-LTE-TSVG Modems: IMEIs and SIM card
ICIDs of all the modems you’d like to activate.
A NimbeLink staff member will contact you to activate the
modems. To activate the NEO SIM for GSM modems, please
follow the directions printed on the AERIS SIM Card.
The NEO SIM (2FF size) must be cut to the nano-SIM (3FF)
form factor in order to fit into the Skywire modems. Use the
template at the following URL to cut your SIM card to size:
http://www.thechinacellphone.com/micro_sim_template.pdf
Activation of an Aeris modem requires
2.12SIM Card Detection (GSM and LTE Only)
Applies to:
- NL-SW-GPRS
- NL-SW-HSPAP
- NL-SW-HSPAPE
- NL-SW-HSPAPG
- NL-SW-LTE-TSVG
- NL-SW-LTE-TNAG
- NL-SW-LTE-TEUG
If you are using a Skywire™ modem that uses a SIM card, you need to
test to make sure the SIM is detected.
In the terminal program, type the letters:
AT#SIMDET?
followed by the enter key. You will receive two responses:
#SIMDET: 1,1 SIM present, no commands required
#SIMDET: 2,1 SIM not present, command required

If you receive #SIMDET: 2,1, type the following letters into the terminal
program:
AT#SIMDET=1
followed by the enter key. This will enable the Skywire™ SIM detection.
2.13Send Modem Activation String (1xRTT and EVDO
only) Applies to:
- NL-SW-1xRTT-V
- NL-SW-EVDO-V
In the terminal program, type the letters:
ATD*22899;
followed by the Enter key, and the module will begin the activation process
which can take several minutes. The terminal should respond with:
OK
#OTASP: 0
#OTASP: 1
#OTASP: 2
NO CARRIER
For all other responses, review network status responses online.
2.14Setup PDP Context (GSM and LTE Only)
Applies to:
- NL-SW-GPRS
- NL-SW-HSPAP
- NL-SW-HSPAPE
- NL-SW-HSPAPG
- NL-SW-LTE-TSVG
- NL-SW-LTE-TNAG
- NL-SW-LTE-TEUG
Before you can successfully communicate with the network using a GSM
or LTE Skywire™, you need to define the PDP context.
For GSM modems:
In the terminal program, type the letters:
AT+CGDCONT = 1,“IP”,”APN”
where APN is the individual APN for your network, followed by the Enter
key, and the terminal program should respond with:

pdf.
In the terminal program, type the letters:
AT+CGDCONT?
followed by the Enter key, and the terminal should respond with:
+CGDCONT: 1,”IP”,”APN”
as well as the other PDP context information on the device. To enable this
setting, in the terminal program type the letters:
AT#SGACT=1,1
followed by the enter key, and the terminal should respond with:
#SGACT: www.xxx.yyy.zzz
where www.xxx.yyy.zzz is the Skywire™ modem’s IP address.
If the AT#SGACT command does not work, the terminal will respond with
#ERROR
and further setup may be necessary. Check the signal strength with
AT+CSQ to verify the Skywire™ is getting an acceptable signal.
Otherwise, consult the Telit AT Command Reference Guide for your
particular modem.
For the Verizon LTE Modem (NL-SW-LTE-TSVG):
In the terminal program, type the letters:
AT+CGDCONT=3, “IP”, “Verizon APN”
where Verizon APN is the specific APN to connect to for your intended
use, followed by the Enter key, and the terminal should respond with:
OK
To get the specific APN setting that you need, please contact Verizon or
contact NimbeLink.
Type the letters:
AT+CGDCONT?
followed by the Enter key, and the terminal should respond with:
+CGDCONT: 3, “IP”, “vzwinternet”
