The modules are accompanied by Fanstel evaluation boards pre-loaded with ‘BlueNor’ mesh testing firmware, enabling users with limited RF design expertise to program and evaluate the modules. Development is further simplified because Nordic’s unique software architecture separates the RF software protocol stack from the developer’s application code eliminating the possibility of code development and compilation corrupting the stack.
Fanstel’s BWG 832F Gateway module is a low cost Bluetooth 5 Wi-Fi module for point-to-point or small mesh network applications where security is either not required or limited decryption and authentication can be implemented in the firmware. The platform comes in a 60 by 60 by 22mm form factor and incorporates an nRF52832 SoC-powered Bluetooth LE module, a Wi-Fi module, and a USB to UART bridge. It relays bidirectional messages between a Cloud server and any node in a mesh network, providing a low cost solution for the mass deployment of IoT products in home, small office, as well as commercial applications.
Nordic’s nRF52832 Bluetooth LE SoC combines a powerful 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software), featuring 512kB Flash memory and 64kB RAM. The SoC is supplied with Nordic’s S132 SoftDevice which also offers mesh capability, enabling scalable networking of the modules.
“We have used Nordic SoCs for our modules for a few years because they offer excellent performance good application examples, and an easy-to-use development environment,” says Dr Yuan Fan, Fanstel Founder and CEO.
“In the nRF52832 SoC, the Arm M4F processor delivers the processing power performance required for our application, at a low cost.”
