NMEA is an acronym for National Marine Electronics Association. All GPS manufacturers, including the cellular module vendors support the standard NMEA GPS data format. This data format enables application developers to use their GPS application across many different GPS devices.
What interfaces are supported for NMEA GPS?
NMEA GPS is supported across variety of interfaces such as USB, RS-232, Bluetooth, UHF, Bluetooth and others.
How is NMEA GPS supported on cellular modules?
In cellular modules that supports GPS feature, NMEA GPS data is generally made available through one of the serial ports. In addition to modem and diagnostics data port, modules that support GPS feature will make NMEA GPS data available through the NMEA port.
How to find the NMEA port in cellular Modules?
Once the manufacturer provided device drivers are installed on the host PC, the NMEA port can be located in the Device Manager.
