9、 Use of relay networking mode
No.
1 After setting the relay mode through the configuration mode, switch to the general mode and the relay starts to work.
In relay mode, ADDH and ADDL are no longer used as module addresses, but are forwarded and paired corresponding to
2 NETID respectively. If one of the networks is received, it will be forwarded to another network. The repeater's own
network ID is invalid.

3 WOR mode transceiver control
WOR receiver (default)
The transceiver of the module is turned on, and
0
when transmitting data, a wake-up code for a
certain period of time is added.
WOR transmitter
The module cannot transmit data and works in
1 WOR monitoring mode. The monitoring cycle
is shown below (WOR cycle), which can save a
lot of power consumption.

Description of relay mode
E90-DTU(400SL33) User Manual
Only valid 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 WOR again. During
this period, the user can input the serial data and
return it through the wireless;
Each serial port byte will be refreshed for
1000ms;
The user must initiate the first byte within
1000ms.
Only valid 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;
The sending and receiving parties must be
consistent (very important)
Write only, read returns 0;
Used for encryption to avoid interception of air
wireless data by similar modules;
Inside the module, these two bytes will be used as
calculation factors to transform and encrypt the
wireless signal in the air.
