WH-L101-H-P datasheet
File Version: V1.0.0
WH-L101-H-P
WH-L101-H-P is high frequency and half-duplex LoRa module which supports point-to-point
communication protocol. Transmitting side and receiving side must meet the following three conditions to
realize point-to-point communication:
communication protocol. Transmitting side and receiving side must meet the following three conditions to
realize point-to-point communication:
⚫
Same speed level.
⚫
Same channel.
⚫
Same target address or both are broadcast address.
WH-L101-H-P supports following three work mode(Note: No matter which mode, one data package length
can’t over 252 bytes, otherwise data package will be discarded):
⚫
can’t over 252 bytes, otherwise data package will be discarded):
⚫
AT command mode: In this mode, user can send AT commands to configure module.
⚫
Transparent transmission mode: In this mode, data transmission procedure won’t influence data content.
⚫
Fixed point mode: In this mode, target address and channel can be changed to switch target module. Based on
transparent transmission mode, first and second bytes of transmitted data will be target address and third
byte will be channel. When module transmits data, target address and channel will be changed and settings
will restore after transmitting.
