Operational description of OEM-Bluetooth low energy module series
NINA-B31
The u-blox NINA-B31 series are small sized radio modules intended for OEM integration utilizing
Bluetooth 5, IEEE 802.15.4, 2.4 GHz proprietary mode and/or NFC. All 2.4 GHz RF-signals share the
same RF-path thus it is not possible to transmit e.g. BLE and 802.15.4 signals simultaneously. The
NFC receiver uses its own interface. It is intended to function as a short-range radio link
transmitting and receiving information between portable and/or fixed electronic devices.
The NFC interface is passive, supporting tag functionality only, and requires an external 13.56 MHz
antenna to operate. An external NFC field is required to activate the NFC block of the module.
The following two different antenna options (hardware options) are available for the NINA-B31
modules:
•
•
NINA-B311 with the RF-port presented at a solder land to be connected to an external
antenna connector using the external antenna reference design (see separate document for
more info). Different types of approved external antennas are available and can be used. See
Table 2 for a list of approved antennas.

Configuration and software security
The NINA-B31 series modules fulfil the requirements of 594280 D01 Software Configuration
Control v02r01. The module has it’s RF-parameters, channel list, power settings etc. stored in nonvolatile memory inside the radio chip, and is controlled by the application software which is preflashed by u-blox. A host system or end-user cannot configure the NINA-B31 module to be noncompliant to regulatory restrictions.
The NINA-B31 modules provide secure boot, which ensures the module only boots up with original
u-blox software.
