|rowspan="3"|After enabling, You can send command 0xC0 0xC1 0xC2 0xC3 to read register in Transmit Mode or WOR Mode; <br />
Register 0x00: RSSI of current ambient noise <br />
Register 0x01: The RSSI of last communicating (current noise of channel is dBm = - RSSI/2); <br />
Command format: 0xC0 0xC1 0xC2 0xC3 + Begin address + Read length;<br />
Answer format: 0xC1 + Address + Read length + Data; <br />
For example:<br />
Command: 0xC0 0xC1 0xC2 0xC3 0x00 0x01 <br />
Answer: 0xC1 0x00 0x01 RSSI (The address should begin from 0x00)

|rowspan="3"|This setting only work for Mode 1;<br />
Receiver waits for 1000ms after receive wirelesss data and forward,and then enter WOR mode again<br />
User can send data to serial port and forward via wireless network during this interval,<br />
Every serial byte will refresh this interval time (1000ms);<br />
You much send the first byte in 1000ms.
|-
|0
|colspan="3"|WOR transmit (default) <br />
Module is enabled to receive/transmit, and wakeup code is added to transmitted data.
|-
|1
|colspan="3"| WOR Sender <br />
Module is disable to send data. Module is working in WOR listen mode. Consumption is reduced

|rowspan="9"|This setting only work for Mode 1;<br />
Period is equal to T = (1 + WOR) * 500ms; MAX 4000ms, MIN 500ms<br />
Longer the Period time of WOR listen, lower the average consumption, however, longer the latency <br />
'''The settings of receiver and sender must be same.'''
