HUAWEI MU609 HSPA LGA Module
Application Guide
Note:
The module's sleep mode is different from working mode or flight mode set using the
AT+CFUN command. The RF will be turned off when the module enters LPM mode using the
command AT+CFUN=0 while the RF will enter DRX mode without being turned off when the
module is in sleep mode. For more details, refer to the latest version of MU609 V100R002 in
HUAWEI MU609 HSPA LGA Module AT Command Interface Specification.
The module enters sleep mode automatically when the sleep task detects that all
other tasks agree on the module's sleep. The sleep period of the module depends on
the current working state and circumstance. The period may last for several seconds,
or up to several minutes.
