The relationship between power and current is
non-linear, and the power supply has the highest
efficiency at maximum power;
The current will not decrease in the same
proportion as the power decreases.
Actual frequency = 410.125 + CH *1M
After being enabled, the module receives wireless
data and outputs it through the serial port TXD,
followed by an RSSI strength byte.
During fixed transmission, the module will
recognize the first three bytes of serial data as:
address high + address low + channel, and use it
as a wireless transmission target.
After enabling, monitoring will be conducted
before wireless data transmission, which can
avoid interference to a certain extent, but may
cause data delay;
The maximum stay time of LBT is 2 seconds, and
it will be issued forcibly when it reaches 2
seconds.
Only valid for mode 1;
Cycle T= (1+WOR)*500ms, the maximum is
4000ms, the minimum is 500ms;
The longer the WOR monitoring interval period,
the lower the average power consumption, but the
greater the data delay;
Both sender and receiver must agree (very
important)
Write only, read returns 0;
Used for encryption to avoid interception of
wireless data in the air by similar modules;
The module will use these two bytes as a
calculation factor to transform and encrypt the air
wireless signal.
