Bluetooth Low Energy (BLE) Wireless Modules Suitable For High-Speed IoT Devices And Applications

Posted by Industry News on

FUJITSU Component Wireless Modules Bluetooth Version 5.0 with Firmware Central/Peripheral FWM7BLZ20B

Fujitsu Components America released their FWM7BLZ20B series of Bluetooth 5.0 Low Energy wireless modules matching the speed demands of Internet-of-Things (IoT) devices and applications.

The FWM7BLZ20B series is powered by Nordic Semiconductor's nRF52832 System-on-Chip (SoC). The symbol rate and data rate supports both 1Mbps and enhanced 2Mbps to expedite communication speed with other Bluetooth devices.

The series comprises two models. The FWM7BLZ20B module contains Fujitsu Components embedded firmware, which allows complex Bluetooth protocol stack handling per plain text commands via UART. It also has "GATT Direct Access Function,” which permits access to other modules through the GATT layer commands. With this function, host equipment can communicate concurrently with up to eight peripherals. It also facilitates communication with other manufacturers’ Bluetooth modules.

FWM7BLZ20B-109077 is a blank module without Fujitsu Components firmware. Users can develop their own firmware including X2 speed and LE advertising extension using tools provided by Nordic Semiconductor. This module includes embedded NFC support function to pair with NFC embedded devices via external antenna.
