E32-400T20S User Manual
between communication parties
The UART baud rate has nothing to do

with wireless transmission parameters
& won't affect the wireless transmit /
receive features.
The lower the air data rate, the longer

the transmitting distance,
anti-interference performance
longer transmitting time
The air data rate must keep the same

for both communication parties.
Except for E32 (400T20S)
Write 0
00H-73FH, correspond to 410~525MHz
In fixed transmission mode, the first

three bytes of each user's data frame can
be used as high/low address and
channel. The module
address and channel when transmit. And
it will revert to original setting after
complete the process.
This bit is used to the module internal

pull-up resistor. It also increases the
level's adaptability in case of open
drain. But in some cases, it may need
external pull-up resistor.
The transmit & receive module work in

mode 0, whose delay time is invalid &
can be arbitrary value.
The transmitter works in mode 1 can

transmit the preamble code of the
corresponding time continuously.
When the receiver works in mode 2,

the time means the monitor interval
