OK

Precautions

After entering low power consumption, send the serial port command again
to wake up;
Because the UART start part byte may be transmitted incorrectly when
transmitting above 40kbps, AT+CLPM=0 may be recognized as an error
and return "+CME ERROR". It is recommended to use "000000000D0A"
(hexadecimal) for wakeup.
