1.6 AT command support
The ODIN-W2 series modules support AT commands as described in the ODIN-W2 AT Commands Manual [1].
See also the s-center software, which is an easy-to-use tool from u-blox for evaluating, and configuration of
u-blox Short Range modules. The s-center tool is available for download on the www.u-blox.com website.
1.7 IEEE 802.11d and additional regulatory domains
The ODIN-W2 series modules support IEEE 802.11d. IEEE 802.11d is an amendment to the IEEE 802.11
specification that adds support for "additional regulatory domains". IEEE 802.11d allows ODIN-W2 based
devices to self-configure and operate according to the regulations of the country in which they operate. Its
parameters include country name, channel quantity and maximum transmission level. The country information
feature simplifies the creation of 802.11 wireless access points and client devices that meet the different
regulations enforced in various parts of the world.
1.7.1 ODIN-W2 IEEE 802.11d implementation description
When ODIN-W2 is used as a Wi-Fi station, the scan is used to detect which regulatory domain it is currently in.
Passive scan is used for channels that are not available in all regulatory domains. The device supports the
following three domains, where WORLD means all channels that are supported both by FCC, ETSI and most
other countries in the world:
•WORLD
•FCC
•ETSI
See Table 3 for detailed information on channels that are supported in the different regulatory domains. The
state transition diagram below (Figure 2) describes the algorithm for selecting the current regulatory domain.
Figure 2: ODIN-W2 series IEEE 802.11d state transition diagram
Initial regulatory domain is WORLD. At start up a scan is initiated to detect beacons containing country
information IEs.
If at least one scan result contains country information indicating FCC and no country information indicates ETSI,
then the regulatory domain is set to FCC.
If at least two scan results contain country information indicating ETSI and no country information indicates FCC,
then the regulatory domain is set to ETSI.

If the scan result contains country information indicating both FCC and country information indicating ETSI, then
the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD_FINAL. This state
will not be exited until the device is reset.
A new scan is performed every hour to update the regulatory domain.
If the current regulatory domain is ETSI and at least one scan result contains country information indicating FCC
and then the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD-FINAL.
This state is will not be exited until the device is reset.
If the current regulatory domain is FCC and at least one scan result contains country information indicating ETSI
and then the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD-FINAL.
This state is will not be exited until the device is reset.
At restart of the device the algorithm is restarted. It is not possible to override the algorithm described by
reconfiguration the device.

The maximum output power is reduced on some channels depending on regulatory requirements. For example,
frequency band edge requirements can limit the output power on channels close to band edges.

2Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
The ODIN-W2 series modules must be supplied through the VCC pin by a DC power supply. Voltage must be
stable, because during operation the current drawn from VCC can vary significantly based on the power
consumption profile of the Bluetooth/Wi-Fi technologies.
2.1.2 Digital I/O interfaces supply output (V_INT)
The ODIN-W2 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated
when the module is powered on. The same voltage domain is used internally to supply the generic digital
interfaces of the modules. The V_INT supply output can be used instead of an external discrete regulator. See
the Electrical specification section for maximum output current.
2.2 Antenna interfaces
The following two different antenna options are available in the ODIN-W2 series:
•ODIN-W260 equipped with dual U.FL. coaxial connectors for external antennas. Different types of
external antennas are available and can be used.
•ODIN-W262 equipped with an integrated dual-band antenna
While mounting the unit, ensure that it does not interfere with radio communication. The ODIN-W262
equipped with an internal surface mounted antenna should not be mounted in a metal enclosure. No
metal casing or plastics using metal flakes should be used. Avoid metallic based paint or lacquer.
See ODIN-W2 series System Integration Manual [2] for information on the external antennas that can be used
and for other RF and antenna design advices.
2.2.1 Antenna connectors and internal antenna
The ODIN-W260 module has two RF antenna U.FL. coaxial connectors with a characteristic impedance of 50 Ω.
The main antenna connector supports both Bluetooth and dual-band Wi-Fi. The second (MIMO) antenna
connector adds support for 2x2 MIMO 2.4 GHz single band Wi-Fi.
The ODIN-W262 module has an internal dual-band PIFA antenna and supports Bluetooth and dual-band Wi-Fi
(SISO).

Figure 3: ODIN-W260 with connectors for external antennas and the ODIN-W262 with an internal antenna
2.3 Data communication interfaces
The ODIN-W2 series provides several data communication interfaces which are described below.
2.3.1 UART interface
The ODIN-W2 series modules include a 6-wire UART for communication with an application host processor (AT
commands, Data communication and firmware upgrades).
The following UART signals are available:
•Data lines (RXD as input, TXD as output)
•Hardware flow control lines (CTS as input, RTS as output)
•Link status (DTR as output, DSR as input)
It is recommended to use CMOS compatible signal levels. See ODIN-W2 AT Commands Manual [1] and ODIN-
W2 series System Integration Manual [2] for more information about the UART interface.
2.3.2 Ethernet interface
Support for an Ethernet interface is planned for version ODIN-W26x-01B-00.
The ODIN-W2 series modules include an integrated Ethernet MAC to communicate with other networked nodes
over a shared medium. It supports 10/100 Mbit/s communication and can operate in both full- and half-duplex
(CSMA/CD).
The Ethernet interface includes:
•RMII either for MAC to PHY or Ethernet MAC to MAC communication.
•SMI for PHY configuration

ODIN-W2 series - Data Sheet
UBX-14039949 - R05 Advance Information Interfaces
Page 12 of 36
The IO voltage of the ODIN-W2 is 1.8 V, which means that the RMII interface operates outside the RMII
specification v1.2. If the RMII is to be connected to a PHY circuit, then that circuit must support 1.8 V
operation. If a direct RMII to RMII connection is used, then a level shifter might be needed depending on
the selected host. The selected hardware setup must be verified on the application board to guarantee
operation.
2.3.2.1 RMII
The RMII uses 7 signals in total. The interface requires an external 50 MHz clock source either from a compatible
PHY chip or an external oscillator. The ODIN-W2 module cannot provide this clock signal by itself.
2.3.2.2 SMI (MDC/MDIO management interface)
The two-wire SMI is used to configure the PHY chips. It uses a clock line and a data line to clock data to and
from the PHY chips registers.

3System functions
3.1 Module power modes
Support for power save mode is available in version ODIN-W26x-01B-00.
The ODIN-W2 series module does not have an internal low power oscillator (LPO) which is required for low
power modes. An external 32.768 kHz LPO signal can be supplied externally via the LPO_CLK pin if low power
modes are required.
3.2 Module reset
The ODIN-W2 series modules can be reset (rebooted) in one of the following ways:
•Low level on the RESET_N pin, which is normally set high by an internal pull-up. This causes «hardware”
reset of the module. The RESET_N line should be driven by an open drain, open collector or contact
switch.
•Using a reset AT command (see the ODIN-W2 AT Commands Manual [1]). This causes «software” reset
of the module.
3.3 System IO
The module has the following six different configurable IOs that can be used to indicate different system states
or to be used as inputs, thus setting the module in different states:
•SWITCH_0
•RED
•GREEN/SWITCH_1
•BLUE
•UART_DTR
•UART_DSR
See the Pin definition section for more information on the separate IOs. For more information on the use and
configuration of the System IOs, see the ODIN-W2 AT Commands Manual [1].
