GPS module¶
Product Parameter¶
Firmware download¶
The firmware defaults to open the GPS.
Modification method¶
GPS is available by default in firmware above, but the public version firmware defaults to close it. You can modify ro.factory.hasGPS
in /system/build.prop
to close or open GPS. Then, please restart your board after completing the modification.
3.Note¶
The GPS function will occupy uart4, so please follow above modification method to close the GPS before using uart4 to do other things.
