Product overview:
  F-9688 Bluetooth module is BLE single-mode data transmission module (suitable for small data very low power transmission, does not support voice, mainly used for control), we supply customer sample is serial port transparent transmission module, other programs, applications need to be customized .

 Module characteristics:
A.BLM world Limited is the first one solved perfectly Android system  (Android 4.4 is perfectly compatible, 4.3 system only supports one-way),IOS system and F-9688 bluetooth module by two-way transmission
B.The user interface uses a universal serial port design, full-duplex two-way communication, and the baud rate ranges from 9600 to 115200 bps
C.the default 20ms connection interval, the connection is fast
D.Support the AT command software reset module to obtain the MAC address.
E.Support AT command to adjust the bluetooth connection interval and control different forwarding rates. (Dynamic power adjustment).
F.Support AT command to adjust the transmit power, modify the broadcast interval, customize the broadcast data, set the data delay (user CPU serial port connection time), modify the serial port baud rate, modify the module name, and save power
G.The serial port data packet length is 20 bytes per pass
H.very low power standby mode
