The host system can set up and control the module through the AT command interface. See u-blox Short Range AT Commands Manual [3] for more information about AT commands. 1.5.1 NINA-B221 The NINA-B221 modules do not use the internal antenna and thus the PCB outline has been trimmed to 10.0 x 10.6 mm. Instead of an internal antenna, the RF signal is available at a module pin for routing to an external antenna or antenna connector. 1.5.2 NINA-B222 The NINA-B222 modules use an integrated antenna mounted on the PCB (10.0 x 14.0 mm). The RF signal pin is not connected to any signal path.

Table 2: NINA-B2 series Bluetooth characteristics 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-B221 and NINA-B222 modules with the u-blox s-center toolbox software using AT commands. See u-blox Short Range AT Commands Manual [3] 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 2.6.2 and in the NINA-B2 series System Integration Manual [1].

NINA-B2 series - Data Sheet UBX-18006649 - R01 Functional description Page 8 of 41 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). MAC address Assignment Last bits of MAC address Example Module 1, address 1 Bluetooth 00 D4:CA:6E:90:04:90 Module 1, address 2 Reserved 01 D4:CA:6E:90:04:91 Module 1, address 3 Reserved 10 D4:CA:6E:90:04:92 Module 1, address 4 Reserved 11 D4:CA:6E:90:04:93 Module 2, address 1 Bluetooth 00 D4:CA:6E:90:04:94 Module 2, address 2 Reserved 01 D4:CA:6E:90:04:95 Module 2, address 3 Reserved 10 D4:CA:6E:90:04:96 Module 2, address 4 Reserved 11 D4:CA:6E:90:04:97 Table 3: Example MAC addresses assignment for two modules 1.9 Power modes The NINA-B2 series modules are power efficient devices capable of operating in different power saving modes and configurations. Different sections of the module can be powered off when not needed and complex wake up events can be generated from different external and internal inputs. For the lowest current consumption modes, an external LPO clock is required (see section 2.2). See the u-blox Short Range AT Commands Manual [3] and NINA-B2 series System Integration Manual [1] for more information about power modes.

NINA-B2 series - Data Sheet UBX-18006649 - R01 Interfaces Page 9 of 41 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 Low Power Clock The NINA-B2 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. The low power clock voltage level is lower (0/0.7 V) compared to the digital signal levels and a voltage divider can be required (see section 4.2.4). 2.3 Module reset The NINA-B2 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 signal should be driven by an open drain, open collector or contact switch. When RESET_N is low (off), the chip works at the minimum power. The NINA-B2 series modules can be reset using an AT command (see the u-blox Short Range AT Commands Manual [3]). This causes a “software” reset of the module. 2.4 Boot strapping pins There are several boot configuration pins available on the module that needs to have the correct settings during boot. It is important that they are in the default state (marked with bold in Table 4) during startup for normal operation. The default state is automatically selected (with internal pull-ups or pull-downs) if the pins are left unconnected. Pin State during boot Default Behavior Description 36 0 VDD_SDIO=3.3V Voltage of Internal Flash 1 10 kΩ pull-up VDD_SDIO=1.8V (VDD_SDIO should always be 1.8 V) 27, 25 00 Download Boot Booting Mode, see section 1.7 for information about 01 Reserved, do not use

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). 2.5.1 Internal antenna The NINA-B222 module has an internal (embedded) 2.4 GHz PIFA antenna. The internal antenna is a PIFA antenna specifically designed and optimized for the NINA form factor. 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 recommended to place the NINA-B222 modules 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. It is beneficial to have a large solid ground plane on the host PCB and have a good grounding on the NINA-B222 module. Minimum ground plane size is 24x30 mm but recommended is more than 50x50 mm. See NINA-B2 series System Integration Manual [1] for more information about antenna related design. The ANT signal is not available on the solder pins of the NINA-B222 module. 2.5.2 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).

See section 0 for detailed information.  If SWITCH_2 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. 2.6.3 UART IO signals In addition to the normal RXD, TXD, CTS, and RTS signals, the NINA-B221/NINA-B222 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/wake up from sleep mode. 2.7 Data interfaces 2.7.1 UART The NINA-B221 and NINA-B222 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 (DTR as output, DSR as input). The DTR/DSR signals behavior is adapted to the u-blox connectivity software functionality and differs from the UART standard, see section 2.6.3 for additional information.  Programmable baud-rate generator allows most industry standard rates, as well as non-standard rates up to 921600 bps.
