5.7 Win8/Android Dual System Switch
H380 module supports Win8/Android dual system switch, check and achieve the system switch
through interrupt signal ”GNSS_IRQ”.
NO. Name Type Description
29 GNSS_IRQ I
Win8/Android dual system switch detection signal ,
CMOS 1.8V
Definition of GNSS_IRQ signal function as listed below :
No. GNSS_IRQ Functions
1 Low/Floating
Support Win8 system, the module`s USB ports shall set as MBIM
modes.
2 High
Support Android system, the module`s `USB ports shall set as 7ACM
modes.
Description:
1. Check and achieve the Win8/Android system switch through GNSS_IRQ level when module boot.
Keep the GNSS_IRQ level stability during booting.
2. Check and achieve the Win8/Android system switch through GNSS_IRQ rising edge/ falling edge, set
ting the de-bouncing time as 100ms. the module will reboot after meeting the requirements and can
switch different system supports.
3. Note:Need high level when switching GNSS_IRQ to android system. Due to internal resistance of
GNSS_IPQ was pulled-up 10K, for achieving high level ,external resistance can not be pulled-up over
20Kohm while circuit design.
5.8 W_DISABLE# Interface
5.8.1 WWAN_DISABLE# Interface Description
H380 module uses the hardware to open / close WWAN RF function signal , the function is also could
