Product Specs

1.Product Overview：
BK3431Q highly integrated bluetooth 5.0 chip BLE bluetooth module USES a single
mode data transmission module, the built-in high-performance transceiver, powerful
baseband processor, built-in FLASH program memory is suitable for the custom
application, the better to defend the security of the application (for small data is extremely
low power consumption, does not support voice, it is mainly used for control), now our
company to the customer the sample module for a serial port passthrough module.
2.Module specification features：
1. Perfect solution for android system (android 4.4 is perfectly compatible, 4.3 only supports
one-way operation)
The problem of two-way pass-through between IOS system and BK3431Q bluetooth module at the
same time.
2. The user interface is designed with a universal serial port and full duplex two-way
communication.
3. Support AT instruction.
