E22-230T22D User Manual
When enabled, the module receives wireless data,
which will follow an RSSI intensity byte when
output through the serial port TXD.
For fixed-point transmission,
identifies the first three bytes of the serial data as:
address high + address low + channel, and uses
them as the wireless transmitting target.
(a) When the relay function is enabled, the
module will initiate a forwarding if the destination
address is not the module itself.
To prevent data backhaul, it is recommended to
use with fixed-point mode; i.e., the destination
and source addresses are different.
When enabled, wireless data is listened to before
it is transmitted, which can avoid interference to
some extent, but may introduce data delays.
The maximum dwell time of LBT is 2 seconds,
and it will be forced to issue when it reaches two
seconds.
Valid only for mode 1.
1. wor's receive mode, the module can modify the
delay time after waking up, the default time is 0.
2. The receiver needs to send the command C0 09
02 03 E8 in configuration mode (C0 is the write
command, 09 is the host initiator address, 02 is
the length, 03 E8 is the set delay time, the
maximum FFFF that is 65535ms, set to 0 to turn
off the wake-up delay).
3. Data can be sent within the delay time
Valid only for mode 1.
Cycle time T= (1+WOR)*500ms, maximum
4000ms, minimum 500ms.
The longer the WOR listening interval cycle time,
the lower the average power consumption, but the
greater the data latency.
Both sending and receiving parties must agree
(very important)
Write only, read returns 0.
for encryption to avoid interception of over-the-air
