BLG840F/X LTE Gateways and BN60 LTE Beacon
Draft Ver 0.51 May 2019
1. Introduction
BLG840F Series gateways integrate Nordic nRF9160 SIP module and Fanstel long range Bluetooth, Thread,
Zigbee module BT840F or BT840X. BN60 has an LTE modem for wide area location tracking. All products are
referred as BLG840F Series in this user’s manual.
Network Interface LTE-M and NB-IoT
It makes the latest low power LTE technology and advanced processing and security accessible, and easy to use,
for a wide range of single device low power cellular IoT (cIoT) designs.
Incorporating an Arm Cortex-M33 application processor solely for applications, a full LTE modem, RF Front End
(RFFE) and power management system. The nRF9160 is the most compact, complete and energy-efficient cellular
IoT solution on the market.
The integrated modem supports both LTE-M and NB-IoT and can operate globally removing any need for regional
variants. All power saving features including eDRX and PSM are supported as is with IPv4/IPv6 support up to
transport and security (TCP/TLS) level. The modem firmware is upgradable via secure, encrypted Firmware Over
The Air (FOTA) updates.
The Arm Cortex-M33 application processor is supported by 1MB of flash and 256kB RAM making advanced
application development possible in a single device solution.
A GPS receiver is integrated into the radio offering various modes of operation to suit a wide selection of
applications that employ location-tracking functionality.
A broad selection of general interfaces and peripherals and are included on nRF9160 including 12-bit ADC, RTC,
SPI, I
²
C, I
²
S, UARTE, PDM and PWM.
Security is best-in-class with Arm TrustZone technology for isolation and protection of normal and secure zones for
firmware and elements of hardware including memory and peripherals. Arm TrustZone helps build solid and secure
IoT applications that feature secure boot, trusted firmware updates and root of trust implementations without
performance compromise.
Arm CryptoCell enhances security still further by offering cryptographic and security resources to help to protect
your IoT applications from various attack threats. CryptoCell is designed for high performance cryptography
solutions optimized for energy-constrained devices.
Gateway and beacon have a SIM connector for connection and authentication with mobile network operators.
Bluetooth, Thread, and Zigbee Interfaces
BLG840F integrates BT840F (nRF52840) module with 2300 meter range at 125 Kbps. BLG840X integrates
BT840X (nR SKY66112 PA) with >4500 meter range at 125 Kbps. BN60 doesn’t integrate a Bluetooth
module.
The nRF52840 is fully multiprotocol capable with full protocol concurrency. It has protocol support for Bluetooth 5,
Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary stacks.
It is built around the 32-bit ARM® Cortex™-M4 CPU with floating point unit running at 64 MHz. It has NFC-A Tag
for use in simplified pairing and payment solutions. The ARM TrustZone® CryptoCell cryptographic unit is included
on-chip and brings an extensive range of cryptographic options that execute highly efficiently independent of the
CPU.
