BLG840F

 

The integrated modem supports both LTE-M and NB-IoT and can operate globally removing any need for regional variants. 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

LTE to Bluetooth 5, Thread, Zigbee IoT Gateways

BLG840F will be pre-certified and is in market ready enclosure. Upon completion of firmware and app development, you can begin marketing products.

A Bluetooth to LTE Gateway (BLG) relays messages from a cloud server to any node in a Bluetooth SIG mesh, other meshes, or in a point to multiple points application.

Using LTE to Connect to a Cloud Server


Development Server

A set of demonstration codes for a BLE 5 sensor sending temperature and humidity data to a BLG840F connected to a Fanstel development server using MQTT protocols can be downloaded from Download OpenSource Document webpage. 

The purpose of development server is to assist developers in early stage of development to trouble-shoot WiFi connection. To avoid overloading, gateways should be connected to a production server as soon as possible.

An Android phone app displaying temperature and humidity as below can be downloaded from the same webpage.

Hex and source codes for use with Mongoose OS to connect to  Google IoT Core cloud server can be downloaded from Download Open Source Document webpage.

Relaying Messages between Cloud and Bluetooth Devices

A Nordic nRF52 module communicates with cloud server in the message layers. nRF52 development environment shall be used for code development. Source codes are available.

The 64 MHz Cortex M4F MCU in nRF52 relays messages between a cloud server and any node in the mesh network. A CryptoCell 310 co-processor is embedded in BT840 Series modules. Secured messages can be decrypted and authenticated when relayed between a cloud server and Bluetooth SIG mesh.

Bootloader is preloaded in Bluetooth module. SoftDevice and application can be loaded by Over-The-Air firmware update. A TAG connect cable TC2050-IDC-NL-050-ALL can be used to connect to nRF52DK to load bootloader and other codes.

BLG840F, Gateway for Industrial Applications

CryptoCell 310 co-processor in BT840F module can offload decryption and authentication of messages, required in Bluetooth SIG mesh. Cortex M4F MCU can relay messages in a large mesh network efficiently. 

For industrial applications or larger mesh network, BWG840F is required to relay messages.
