Feature:
Working
frequency:
2400~2450MHz
(16
channels
total).
Communication
Interface:
UART
serial
port
(supports
13
baud
rates,
2400,
4800,
9600,
14400,
19200,
28800,
38400,
57600,
115200,

125000,
250000,

Self-organizing
network
hops:
<=15
jump.
Single
hop
transmission
distance:
70
meters
(out
of
the
air,
no
occlusion
test).
Number
of
points
that
can
be
accommodated:
The
typical
value
is
190.
When
the
network
tends
to
be
dense,
the
number
of
nodes
decreases,
and
the
minimum
value
is
96.
MAX
packet
length:
63Byte
(including
port
address
information).
Transmission
capacity:
The
transmission
rate
is
higher
when
only
one
node
sends
data:
Because
the
routing
information
of
the
transmitted
packet
occupies
a
certain
bandwidth,
the
longer
the
length
of
each
packet,
the
higher
the
transmission
efficiency.
2400
Bit/s
when
each
package
contains
3
bytes
of
data.
10KBit/s
when
each
package
contains
30
bytes
of
data.
MAX
send
rate:
250KBit/s.
Packet
retransmission
times:
Up
to
15
times,
at
least
5
times
when
the
network
load
is
high.
Air
delay:
Single-hop
between
nodes,
less
than
10mS.
Transmit
power:
4.
5dBm.
Operating
Voltage:
2.
5V~3.
6V.
Working

Less
than
30mA.

If
this
pin
is
grounded
first
and
then
the
module
is
started,
the
module
will
force
a
115200
default
baud
rate
to
operate.
In
this
mode,
the
baud
rate
of
the
module
can
be
read
or
set.
The
baud
rate
read
is
the
baud
rate
previously
set
by
the
module,
not
115200.
If
the
baud
rate
setting
is
not
performed,
the
module
will
be
restarted
again.
Work
with
the
previously
set
baud
rate.
