E32-433T20S1 user manual
UART baud rate can be different 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 and 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
