How to use (>= 2pcs):
1 2PCS, Module 1 and Module 2 send data to each other.
2 3PCS, module 1 sends data, module 2 acts as a repeater (multiple repeaters can be used), and module 3 receives data; delay sending and receiving distance.
3 >= 3PCS, one as the master device and the other as the slave device.
The way they work as well as a wired RS485 bus. The master device sends data, and both slave devices receive data. Any slave device sends data, and the master device and other slave devices can receive it. Previously only one device (master or slave) was allowed to send data.
