WOR transmitter

The

module

receiving

and

transmitting functions are turned on, and a

wake-up code is added when transmitting data.

Receiving is turned on.

WOR receiver

default

The module is unable to transmit data

and works in WOR monitoring mode. The

monitoring period is as follows (WOR cycle),

which can save a lot of power.

When enabled, the module receives wireless data

and it will follow an RSSI strength byte after output

via the serial port TXD

.---------------------------------------

The module recognizes the first three bytes of the

serial data as: address high + address low + channel

and takes it as the wireless transmitting target.

---------------------------------------

After the reply function is enabled, if the target

address is not the module itself, the module will

forward it once.

In order to prevent data return-back, it is

recommended to use it in conjunction with the fixed

point mode. That is: the target address is different

from the source address.

----------------------------------------

When enabled, wireless data will be monitored

before it is transmitted, which can avoid interference

to a certain extent, but may cause data delay.

----------------------------------------

Valid only for mode 1.

After the WOR receiver receives the wireless data

and outputs it through the serial port, it will wait for

1000ms before entering the WOR again. Users can

input the serial port data and return it via the wireless

during this period. Each serial byte will be refreshed

for 1000ms. Users must transmit the first byte within

1000ms.

---------------------------------------------

Valid only for mode 1.

Period T = (1 + WOR) * 500ms, maximum 4000ms,

minimum 500ms

The longer the WOR monitoring interval period, the

lower the average power consumption, but the

greater the data delay

Both the transmitter and the receiver must be the

same (very important).
