4.4 RF Interface
WSL05-A0 module requires 50Ω impedance characteristics of antenna, the cabling from
module ANT interface to antenna also needs to be controlled within this impedance range.
The reference circuit is shown below.

5 Application Function
5.1 Working Mode
WSL05-A0 module supports AT command and transparent transmission mode. Different
working modes have different data processing.
AT command mode can only receive AT commands, which can be used for data
transmission, parameter configuration, and status reading, etc.
All data received in the transparent transmission mode is regarded as a payload and is
only used for data transmission.
