1.1 Introduction to the 2.4 G wireless solutions
2.4 G wireless rf treatment scheme is to use BK2425 MCU data for effective combination
form for high speed transmission of a device to send and receive treatment scheme, complete
solution contains a sender and a receiver
。
1.2 A brief introduction AI-BS-WS40-V wireless solutions
AI-BS-WS40-V wireless solutions using STM32FC8T6 (MCU) + Si4438 (RF) way to realize wireless
sending and receiving data.

Data interface
2.4 G&RF 433 wireless data interface can be divided into the sending end of data interface and data
interface at the receiving end.
2.1 The data interface of sender
2.1.1 Barcode scanning decoding module connection
Interface circuit for a FPC (0.5 mm to 12 p) interface communicate with barcode scanning module,
mainly through the wireless MCU interface receives the barcode scanning module, transmission of
data and processing.
