February 28, 2019 -- Fujitsu Components America released the FWM7BLZ20B series of Bluetooth 5.0 Low Energy wireless modules to meet the speed requirements of IoT devices and applications.
The FWM7BLZ20B series is powered by Nordic Semiconductor's nRF52832 SoC. The symbol rate and data rate accommodates both 1Mbps and improved 2Mbps to facilitate communication speed with other Bluetooth devices.
The series includes two models. The FWM7BLZ20B module contains Fujitsu Components embedded firmware, which enables complicated Bluetooth protocol stack handling by simple text commands via UART. It also has "GATT Direct Access Function,” which enables access with other modules through the GATT layer commands. With this function, host equipment can communicate simultaneously 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 unique 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.
