2.3 Antenna Characteristics
The antenna is monopole type of chip antenna. The antenna impedance matching is optimized
for 1 mm ~ 2 mm mother board PCB thickness. The radiation pattern is impacted by the layout of
the mother board. Typically the highest gain is towards GND plane and weakest gain away from the
GND plane.

3. Terminal Description
3.1 UART Interface
This is a standard UART interface for communicating with other serial devices.
BT-MSOII UART interface provides a simple mechanism for communicating with other serial devices
using the RS-232 protocol.
When BT-MSOII is connected to another digital device, UART_RX and UART_TX transfer data
between the 2 devices. The remaining a signal, UART_CTS implement optional RS232 hardware flow
control
3.2 SPI Interface (Debug only)
BT-MSOII provides a debug SPI interface for programming, configuring and debugging the BT-MSOII.
Access to this interface is required in production. Ensure the 4 SPI signals externally.
3.3 I2C Interface
BT-MSOII supports a firmware controlled I²C interface to communicate with external Device.
The I²C timing is compliant with the Philips I²C Specification (100 kHz and 400 kHz).
13
4. Reset, RST#
BT-MSOII is reset from several sources:
▪ RST# pin
▪ Power-on reset
▪ UART break character
The RST# pin is an active low reset and is internally filtered using the internal low
frequency clock oscillator. CSR recommends applying RST# for a period >5ms.

■ Notice
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference
that may cause undesired operation.
This device complies with Industry Canada’s licence-exempt RSSs. 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.
The module is limited to OEM installation ONLY.
OEM integrators are responsible for ensuring that the end-user has no manual
instructions to remove or install module.
The module is limited to installation in mobile or fixed applications, according to
Part 2.1091(b).
Separate approval is required for all other operating configurations, including
portable configurations with respect to Part 2.1093 and different antenna
configurations.
For a host manufacture’s using a certified modular, if (1) the module’s FCC ID is
not visible when installed in the host, or (2) if the host is marketed so that end
users do not have straightforward commonly used methods for access to remove
the module so that the FCC ID of the module is visible; then an additional
permanent label referring to the enclosed module: “Contains Transmitter
Module FCC ID: 2AKMF-BT-MSOII” or “Contains FCC ID: 2AKMF-BT-MSOII”
must be used. The host OEM user manual must also contain clear instructions on
how end users can find and/or access the module and the FCC ID.
Canada certification label of a module shall be clearly visible at all times when
installed in the host product; otherwise, the host product must be labelled to
display the Canada certification number for the module, preceded by the word
“Contains” or similar wording expressing the same meaning, as follows:
Contains IC : 22266-BTMSOII

■ Warning - U.S.A
i) Changes or modifications not expressly approved by the manufacturer could
void the user's authority to operate the equipment.
ii) Caution: Exposure to Radio Frequency Radiation.
To comply with FCC RF exposure compliance requirements, a separation distance
of at least 20 cm must be maintained between the antenna of this device and all
persons.
Afin de se conformer aux exigences en matière d'exposition aux
rayonnements radioélectriques, une distance de séparation d'au moins 20 cm
doit être maintenue entre l'antenne de cet appareil et toutes les personnes.
