Important
Notice
Due to the nature of wireless communications, transmission and reception of data can
never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally
lost. Although significant delays or losses of data are rare when wireless devices such
as the Sierra Wireless modem are used in a normal manner with a well-constructed
network, the Sierra Wireless modem should not be used in situations where failure to
transmit or receive data could result in damage of any kind to the user or any other
party, including but not limited to personal injury, death, or loss of property. Sierra
Wireless accepts no responsibility for damages of any kind resulting from delays or
errors in data transmitted or received using the Sierra Wireless modem, or for failure
of the Sierra Wireless modem to transmit or receive such data.
Safety and
Hazards
Do not operate the Sierra Wireless modem in areas where blasting is in progress,
where explosive atmospheres may be present, near medical equipment, near life
support equipment, or any equipment which may be susceptible to any form of radio
interference. In such areas, the Sierra Wireless modem MUST BE IN AIRPLANE
MODE OR POWERED OFF. The Sierra Wireless modem can transmit signals that
could interfere with this equipment.
Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on
the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE IN
AIRPLANE MODE OR POWERED OFF. When operating, the Sierra Wireless modem
can transmit signals that could interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground
and the door is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem
while in control of a vehicle. Doing so will detract from the driver or operator's control
and operation of that vehicle. In some states and provinces, operating such
communications devices while in control of a vehicle is an offence.
Limitation of
Liability
The information in this manual is subject to change without notice and does not
represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS
AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT,
INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR
EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS
OR REVENUE OR ANTICIPATED PROFITS OR REVENUE ARISING OUT OF THE
USE OR INABILITY TO USE ANY SIERRA WIRELESS PRODUCT, EVEN IF
SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR
CLAIMS BY ANY THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates
aggregate liability arising under or in connection with the Sierra Wireless product,
regardless of the number of events, occurrences, or claims giving rise to liability, be in
excess of the price paid by the purchaser for the Sierra Wireless product.

4: Interfaces Specification
4.1 Overview
This section describes the interfaces supported by the AirPrime BX310x embedded
module and provides specific voltage, timing, and circuit recommendations for each
interface.
4.2 UART
The AirPrime BX310x provides one UART interface for asynchronous communication
between the AirPrime BX310x module and a host device (e.g. a PC or host
processor):
• UART0—4-wire, RS-232-compliant interface
Note: Up to two additional UART interfaces can be added by configuring GPIOs using AT
commands.
Flow control is managed using:
• RTS/CTS signals (This method is required for higher UART interface speeds.)
or
• Software XON/XOFF
Table 4-1 on page 23 describes the signals used for UART0.
Note: UART signals are named with respect to the module, and directions are listed with
respect to the module. For example, UART0_RXD is an output from the module to the host.

4.3 ADC
The AirPrime BX310x provides two general purpose ADC (Analog to Digital
Converter) inputs that are used to measure analog voltages.
4.4 Voltage Measurement
The AirPrime BX310x supports the measurement of analog voltages using the
following methods:
• ADCs—Two input pins that can be used for direct voltage measurements. See
ADC on page 24.
• Combination of four GPIOs and external capacitors—Small analog signals can
be measured by configuring (using AT commands) the pins in Table 4-3 below to
support a low-noise programmable gain amplifier with the addition of external
270 pF capacitors between pins 31/32 and pins 34/36. The internal ULP-copro-
cessor is also designed to measure the voltages while operating in the sleep
mode, to enable low power consumption; the CPU can be woken up by a
threshold setting and/or via other triggers.
4.5 I2
C Interface
The AirPrime BX310x module provides two I2
C (Inter-Integrated Circuit) dedicated
serial ports (bus interface) based on [8] The I2C Bus Specification, Version 2.1,
January 2000 (Phillips Semiconductor document number 9398 393 40011).

A user manual with the end product must clearly indicate the operating requirements
and conditions to ensure compliance with current FCC RF exposure guidelines.
The end product with an embedded BX3100/BX3105 module may also need to meet
the FCC Part 15 unintentional emission requirements and be properly authorized per
FCC Part 15 Subpart B.

Regulatory Certifications
Rev 2 Oct.17 31 41111444
Canada
The BX3100/BX3105 module, upon commercial release, will have been granted
modular approval by IC. Integrators may use the BX3100/BX3105 module in their end
products without additional IC certification if the following conditions are met.
• At least 20 cm separation distance between the antenna and the user’s body
must be maintained at all times.
• The BX3100/BX3105 module must not be collocated with any other transmitter
within a host device.
• The regulatory label on the end product must include the text “Contains IC : TBD”
and the following compliance statement:
This device complies with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including
interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux
appareils radio exempts de licence. L'exploitation est autorisée aux deux
conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2)
l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même
si le brouillage est susceptible d'en compromettre le fonctionnement.
Bluetooth Qualification Program (BQP)
• In case no other non-certified Bluetooth components are incorporated, the
BX3100/BX3105's BQP marking certification allows users to integrate the module
into products without the need to obtain subsequent and separate approval.
• The BX3100/BX3105 has been approved by the Bluetooth Qualification Body
(BQB) to use the Bluetooth trademark and to offer official Bluetooth functionality.
The approval according to the V4.2 Bluetooth specification confirms that the
module complies with the Bluetooth specification and will successfully operate
with other products supporting the same profile. BQP certification also ensures
that the module has gone through safety assessment. This certification was
granted through a combination of product performance testing and interoperability
testing. This certification applies globally.
Labelling
• Products complying with all relevant requirements are allowed to bear the official
Bluetooth logo

6: Pinout
The system interface of the AirPrime BX310x is through the LGA pattern on the
bottom of the PCB.
AirPrime BX310x pins are divided into three functional categories:
• Core functions and associated pins—Cover all the mandatory features for M2M
connectivity and will be available by default across all CF3 family of modules.
These Core functions are always available and always at the same physical pin
locations. A customer platform using only these functions and associated pins is
guaranteed to be forward and/or backward compatible with the next generation of
CF3 modules.
• Extension functions and associated pins—Bring additional capabilities to the
customer. Whenever an Extension function is available on a module, it is always
at the same pin location.
• Custom functions and associated pins—These are module-specific and make
use of specific chipset functions and I/Os.
Warning: Custom features should be used with caution as there is no guarantee that the
custom functions available on a given module will be available on other CF3 modules.
Pins marked as "Leave open" or "Reserved" should not be used or connected.
