2.4.3.2 Permanent termination of Low Power Mode
The module low power mode is enabled and disabled by the ATS24 command.
To permanently terminate the low power mode, the ATS24 = 0 command must be used. Setting ATS24 =
0 disables the currently active low power mode and switches the module to Idle mode.
The module will not return to low power mode until an ATS24 > 0 commands is set again.
