This module is a SMD BLE module used in BLE Bee and Xadow BLE.
This is a SMD BLE module used in our BLE Bee and Xadow BLE. It is based on TI cc2541 chip, enables robust network nodes to be built with low total bill-of-material costs and highly suited for ultralow power consumption systems. The module is small and easy to use, with the preprogrammed firmware of manufacturer, you can quickly build BLE communications via its AT command. Supporting BLE communications with iphone, ipad and Android 4.3.
It’s working frequency is 2.4 GHz ISM band & Interface way is a serial port.
Modulation method is GFSK (Gaussian Frequency Shift Keying).
