E32-433T20DC user manual
 UAR T baud rate can be different
between communication parties

The UAR T 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-1FH, correspond to 410~441MHz
 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 changes its
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
better
