8.5.3 Advantages
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.
