HUAWEI ME909u-521 LTE LGA Module
Application Guide		Sleeping and Waking Up Application Scenarios

		number of text messages exceeds
		the limit (^SMMEMFULL). Other
		unsolicited messages are saved in
		the cache when the host is in sleep
		mode, and reported to the host when
		it wakes up.
		When the host is awake, unsolicited
		messages are reported to the host.

OK

8.5.3Advantages

A solution is provided for systems not supporting USB remote resume.

With software configuration, while the system requirements (calling and text messages) are met, the number of times the host is woken up by unsolicited messages, and consequently the power consumption, are reduced.

8.6 System with Other Connection Methods

If the host can be connected to the module only using UART, refer to the HUAWEI ME909 Series LTE LGA Module Brief Hardware Guide. If the host can connect to the module using USB/UART/WAKEUP_OUT and can support USB remote wake-up and UART remote wake-up, prioritize USB remote wake-up over WAKEUP_OUT remote wake-up. For details about the software procedure, refer to the earlier sections while considering the host system feature.
