AT command problems with AT+ChipID=?

I have a HTTC-AB02S board and I want to send AT commands withe the arduino Ide.
When I send: AT+ChipID=?
The response is:
18:22:49.322 -> ASR is Waked,LowPower Mode Stopped
18:22:51.422 -> +ERROR: Use “AT+ChipID=?” to get the ChipID
18:23:01.439 -> Auto LowPower Mode
The response is to use exactly the same command I send …
Thanks for answers

Sorry, I found my mistake:
Make sure there is NO ending characters or new line in you serial monitor config!
This solved my problem.
