JDY-40 wireless serial port module soft reset?

[jesuscf]

Hi everybody,

Is there an undocumented 'AT' command that would soft reset the JDY-40 wireless serial port module?  So far, these are the commands that seem to work:

Command: AT+VER
Response: +JDY-40-V2.2
Command: AT+BAUD
Response: +BAUD=4
Command: AT+RFID
Response: +RFID=8899
Command: AT+DVID
Response: +DVID=1122
Command: AT+RFC
Response: +RFC=001
Command: AT+POWE
Response: +POWE=9
Command: AT+CLSS
Response: +CLSS=A0

I am asking because any changes in the configuration of the module are only reflected after it is power cycled.  I've tried 'AT+RST' but it doesn't do anything.
