hi. i have a em7430 module in hand ,I use it on win 10 system.
Looking at the AT!GPSAUTOSTART command manual, it is described as follows.
Parameters: <function> (Enable / disable the feature)
• 0 = Disabled
• 1 = Enabled at boot (GPS tracking session starts automatically when modem is reset)
• 2 = Enabled when NMEA port is opened
I tested the gps with the function =1 , in the open area .I can get the cuttent location on the window10 map.
but when i entered the room with the poor GPS signal . I can not get the location on the window 10 map.
but I found if I set the function value=2, value 2 is much faster to get the current location on the map than Value 1… A problem occurs when the setting value of GPSAUTOSTART is 1 ,I can’t get the the current location .It does not occur when the set value is 2.
as I understand ,the Function =1 mean the GPS start when the win10 system is power up.
the function =2 mean the gps start when the app software such as MAP is running
please give the explainaton for the the function value =1 and 2.
thanks a lot
