1.7 Software options

The NINA-B2 series modules come with the pre-flashed application software, supporting Bluetooth

BR/EDR and Bluetooth Low Energy. The host system can set up and control the module through the

AT command interface. The NINA-B2 modules provide top grade security, thanks to secure boot,

which ensures the module boots up only with original u-blox software. This makes NINA-B2 ideal for

critical IoT applications where security is important.

1.7.1 AT command support

You can configure the NINA-B2 modules with the u-blox s-center toolbox software using AT

commands. See u-connect AT commands manual [3] and u-connectXpress software user guide [7]

for information about supported AT commands.

The s-center evaluation software supporting the AT commands is also available free of charge and

can be downloaded from the u-blox website.

1.7.2 Software upgrade

Information on how to upgrade the software for NINA-B2 series is provided in section 2.4.2 and in the

NINA-B2 series system integration manual [1].

1.8 MAC addresses

The NINA-B2 module series has four unique consecutive MAC addresses reserved for each module

and the addresses are stored in the configuration memory during production. The first Bluetooth

address is available in the Data Matrix on the label (see section 9.1).

2 Interfaces

2.1 Power supply

The power for NINA-B2 series modules is supplied through VCC and VCC_IO pins by DC voltage.

☞ The system power supply circuit must be able to support peak power (add 20% as margin over the

listed type current consumption), as during operation, the current drawn from VCC and VCC_IO

can vary significantly based on the use cases.

2.1.1 Module supply input (VCC)

The NINA-B2 series modules use an integrated Linear Voltage converter to transform the supply

voltage presented at the VCC pin into a stable system voltage.

2.1.2 Digital I/O interfaces reference voltage (VCC_IO)

All modules in the NINA-B2 series provide an additional voltage supply input for setting the I/O voltage

level. The separate VCC_IO pin enables integration of the module in many applications with different

voltage levels (for example, 1.8 V or 3.3 V) without any level converters. The NINA-B2 modules support

only 3.3 V as IO voltage level currently.

2.2 System functions

NINA-B2 series modules are power efficient devices capable of operating in different power saving

modes and configurations. Different sections of the modules can be powered off when they are not

needed, and complex wake up events can be generated from different external and internal inputs.

The next sections describe the system power modes in detail as well as power-on/off and reset

behavior, and boot strapping options.

The following system power modes available:

• Automatic:

o Active mode

o Standby mode

• Manual:

o Sleep mode

o Stop mode

2.2.1 Module power on

You can switch on or reboot the NINA-B2 series modules in one of the following ways:

• Rising edge on the VCC pin to a valid supply voltage

• Issuing a reset of the module (see section 2.2.7)

If the u-connect software has been configured to start in AT mode, +STARTUP will be sent over the

UART interface when the software has booted and is ready to accept commands.

2.2.2 Module power off

There is no dedicated pin to power down the NINA-B2 series modules. Instead, the “Stop” power mode

can be used to keep the module the module in the deepest power save mode. The stop mode is more

power efficient than holding the module in reset.

UBX-18006649 - R07 Interfaces Page 12 of 46

C1 - Public

2.2.3 Active mode

In this mode the module is actively transmitting or receiving data over one or more of its interfaces;

2.4 GHz radio, UART etc. The module CPU is operating at its highest clock speed. The module will

switch between Active mode and Standby mode automatically and seamlessly without user

involvement.

2.2.4 Standby mode

In this mode the module is considered to be “idling”, with only background activity. Any radio or

physical connections are maintained and no data packets will be lost if received in this mode. When

required, the module will automatically and without delay enter Active mode.

The user can further decrease the current consumption in Standby mode by:

• Enabling Automatic Frequency Adaption (AFA)

• Increasing the Bluetooth low energy connection interval

Automatic Frequency Adaption (AFA) allows the internal clocks to be automatically reduced whenever

possible. This is configured using the AT+UPWRMNG command.

☞ Enabling AFA can put limits on certain module functions, maximum UART baud rate etc. Check

the u-connect AT commands manual [3] to determine which clock speeds are acceptable for your

application.

☞ See the u-connect AT commands manual [3] and u-connectXpress software user guide [7] for

more information on how to use AT commands to configure the u-connectXpress software.

2.2.5 Sleep mode

☞ Sleep mode is not available in NINA-B2.

2.2.6 Stop mode

Stop mode is the deepest power saving mode of the NINA-B2 modules. During Stop mode, all

functionality is stopped to ensure minimum power consumption; all existing connections will be

dropped, and the system RAM will not be retained. The module always reboots when waking up from

Stop mode.

Stop mode must be actively entered into by the user in one of the following ways:

• Using the AT&D4 command, and the UART DSR pin to enter/leave Stop mode

• Using the AT+USTOP command, and a GPIO pin set by the user to enter/leave Stop mode. See

Table 6 for GPIOs capable of controlling Stop mode.

• Using the AT+USTOP command, and setting a timer to automatically wake up after a delay set

by the user.

If the u-connect software has been configured to start in AT mode, +STARTUP will be sent over the

UART interface when the software has booted and is ready to accept commands.

☞ See the u-connect AT commands manual [3] and u-connectXpress software user guide [7] for

more information on how to use AT commands to configure the u-connectXpress software.

2.2.7 Module reset

The NINA-B2 series modules can be reset (rebooted) in the following way:

NINA-B2 series - Data sheet

UBX-18006649 - R07 Interfaces Page 13 of 46

C1 - Public

• Low level on the RESET_N pin, which is normally set high by an internal pull-up. This results in a

“hardware” reset of the module. The RESET_N signal should be driven by an open drain, open

collector or contact switch.

☞ The NINA-B2 series modules can be reset using an AT command (see u-connect AT commands

manual [3]). This causes a “software reset” of the module.

☞ Holding the module in reset does not result in the lowest power consumption. Instead, put the

module in “Stop mode” (see section 2.2.6).

2.2.8 Boot strapping pin

There are several boot configuration pins available on the module that must have the correct settings

during boot (see Table 4). The boot strap pins are configured to the default state internally on the

module and must NOT be configured externally.

During boot, pin 32 controls if additional system information should be transmitted on the UART

interface during startup. After the system has booted it is reconfigured to SPI_CS, the SPI chip select

signal.

During boot, pin 36 controls the voltage level of the internal flash during startup. After the system

has booted it is reconfigured to SPI_MISO, the SPI slave data output signal. It must NOT be pulled

down by an external MCU or circuitry

Table 4: NINA-B2 series boot strapping pin

2.3 RF antenna interface

The RF antenna interface of the NINA-B2 series supports Bluetooth BR/EDR and Bluetooth Low

Energy on the same RF antenna signal. The module is equipped with a 2.4 GHz bandpass filter

between the radio chip and RF antenna interface (see section 1.4).

The NINA-B2 series supports either an internal antenna (NINA-B222) or external antennas connected

through an antenna pin (NINA-B221).

2.3.1 Internal antenna

NINA-B222 has internal antenna specifically designed and optimized for the NINA module, which is a

2.4 GHz PIFA antenna.

It is recommended to place the NINA-B222 module in such a way that the internal antenna is in the

corner of the host PCB (the corner closest to Pin 16 should be in the corner). The antenna side (short

side closest to the antenna), positioned along one side of the host PCB ground plane is the second

best option.

For NINA-B222 keep a minimum clearance of 5 mm between the antenna and the casing. Keep a

minimum of 10 mm free space from the metal around the antenna including the area below. If a metal

enclosure is required, use NINA-B221 and an external antenna. It is beneficial to have a large solid

NINA-B2 series - Data sheet

C1 - Public

ground plane on the host PCB and have a good grounding on the module. Minimum ground plane size

is 24x30 mm but recommended is more than 50x50 mm.

See the NINA-B2 series system integration manual [1] for more antenna related design information.

⚠ The ANT signal is not available at the solder pins of the NINA-B222 module.

2.3.2 External RF antenna interface

The NINA-B221 module has an antenna signal (ANT) pin with a characteristic impedance of 50 Ω for

using an external antenna. The antenna signal supports both Tx and Rx.

The external antenna, for example, can be an SMD antenna (or PCB integrated antenna) on the host

board. An antenna connector for using an external antenna via a coaxial cable could also be

implemented. A cable antenna might be necessary if the module is mounted in a shielded enclosure

such as a metal box or cabinet.

An external antenna connector (U.FL. connector) reference design (see NINA-B2 series system

integration manual [1]) is available and must be followed to comply with the NINA-B2 FCC/IC modular

approvals. Also see the list of approved antennas (section 7.2).

2.4 IO signals

2.4.1 System status IO signals

The RED, GREEN and BLUE pins are used to signal the status. They are active low and are intended

to be routed to an RGB LED. See the u-connect AT commands manual [3] for more information about

connectivity software signals IOs.

Mode Status RGB LED color GREEN BLUE RED

Data mode IDLE Green LOW HIGH HIGH

Command mode IDLE Orange LOW HIGH LOW

Data mode, Command mode CONNECTING* Purple HIGH LOW LOW

Data mode, Command mode CONNECTED* Blue HIGH LOW HIGH

* = LED flashes on data activity

Table 5: System status indication

2.4.2 System control IO signals

The following input signals are used to control the system (see u-connect AT commands manual [3]

for more information about connectivity software signals IOs):

• RESET_N is used to reset the system. See section 2.4 for detailed information.

• If SWITCH_1 is driven low during start up, the UART serial settings are restored to their default

values.

• SWITCH_2 can be used to open a connection to a peripheral device.

• If both SWITCH_1 and SWITCH_2 are driven low during start up, the system will enter the

bootloader mode.

• If both SWITCH_1 and SWITCH_2 are driven low during start up and held low for 10 seconds, the

system will exit the bootloader mode and restore all settings to their factory defaults.

2.4.3 UART IO signals

In addition to the normal RXD, TXD, CTS, and RTS signals, described in section 2.5.1, the NINA-B2

software adds the DSR and DTR pins to the UART interface. Note that they are not used as originally

intended, but to control the state of the NINA module. Depending on the current configuration, the

DSR pin can be used to:

• Enter command mode

• Disconnect and/or toggle connectable status

• Enable/disable the rest of the UART interface

• Enter/leave Stop mode

2.5 Data and command interfaces

There are two data interfaces available on a NINA-B2 module: UART and SPI. Both interfaces cannot

be used at the same time. After the module has booted, the module will check for activity on both

interfaces to determine which of the interfaces should be used. AT commands can always be used to

enable or disable interfaces manually. Figure 2 shows the startup and interface selection procedure.

Figure 2: Interface detection flow chart

☞ +STARTUP will always be printed on the UART TXD line.

When the SPI detection is started, the NINA-B2 module will start toggling the SPI_DRDY signal

periodically. Once the SPI master has sent 8 clock signals on the SPI_SCLK line, the SPI interface is

considered to be active and the UART interface is disabled.

If an AT command is sent to the NINA-B2 module over the UART interface, the UART interface will be

considered “detected”, and the SPI_DRDY signal will stop toggling and the SPI interface will be

disabled.

☞ See the u-connectXpress Software User Guide [7] for more information on how to use these data

and command interfaces.

2.5.1 UART

The NINA-B2 modules include a 6-wire UART for communication with an application host processor

(AT commands, Data communication and software 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 (DSR as input, DTR as output). The DSR/DTR signals behavior is adapted to the u-

connectXpress software functionality and differs from the UART standard, see section 2.4.3 for

additional information.

• Programmable baud-rate generator allows most industry standard rates, as well as non-standard

rates up to 3 Mbaud.

• Frame format configuration:

• 8 data bits

• Even or no-parity bit

• 1 stop bit

• Default frame configuration is 8N1, meaning eight (8) data bits, no (N) parity bit, and one (1) stop

bit.

2.5.2 SPI

The serial peripheral interface of NINA-B2 only runs in “SPI slave mode”, meaning a host controller

running in “SPI master mode” is intended to send commands to the NINA module.

The following signals are used:

• SPI_SCLK – Serial clock input signal

• SPI_MOSI – Serial data input signal

• SPI_MISO – Serial data output signal

• SPI_CS – Chip Select input, enable control signal

• SPI_DRDY – (optional) Additional “Data Ready” output signal, used to indicate to the controller

when data is available. This signal can be disabled, but is enabled by default.

• SPI_NORX – (optional) Additional flow control output signal used to indicate when the NINA module

cannot receive any more data. This signal is not enabled by default.

An SPI master must comply with the following:

• 10 MHz maximum clock speed

• SPI mode 1 or 3

• The SPI master must clock at least 8 bytes minimum and 4096 bytes maximum per transaction,

and transaction lengths must be on 4 byte boundary

☞ See the following application note for more information on how to use the SPI interface [6].

☞ The grey pins in the center of the modules are GND pins. The lower part below the dotted line is

the antenna part of NINA-B222 and the outline of the NINA-B221 module ends at this line.

☞ Some of the signals are boot strap signals (see Table 6). It is important that these signals are in

the correct state during startup (see section 2.2.8).

8.2 Moisture sensitivity levels

⚠ The NINA-B2 series modules are Moisture Sensitive Devices (MSD) in accordance with the

IPC/JEDEC specification.

The Moisture Sensitivity Level (MSL) relates to the required packaging and handling precautions. The

NINA-B2 series modules are rated at MSL level 4. For more information regarding moisture sensitivity

levels, labeling and storage, see the u-blox package information guide [2]

☞ For MSL standards, see IPC/JEDEC J-STD-020, which can be downloaded from www.jedec.org.

8.3 Reflow soldering

Reflow profiles are to be selected according to u-blox recommendations. See NINA-B2 series system

integration manual [1] for more information.

⚠ Failure to observe these recommendations can result in severe damage to the device.

8.4 ESD precautions

⚠ The NINA-B2 series modules contain highly sensitive electronic circuitry and are Electrostatic

Sensitive Devices (ESD). Handling the NINA-B2 series modules without proper ESD protection may

destroy or damage them permanently.

The NINA-B2 series modules are electrostatic sensitive devices (ESD) and require special ESD

precautions typically applied to ESD sensitive components. Section 4.1.1 provides the maximum ESD

ratings of the NINA-B2 series modules.

Proper ESD handling and packaging procedures must be applied throughout the processing, handling

and operation of any application that incorporates the NINA-B2 series module. The ESD precautions

should be implemented on the application board where the module is mounted as described in the

NINA-B2 series system integration manual [1].

⚠ Failure to observe these recommendations can result in severe damage to the device.
