This format can...
read waypoints
read tracks
This format has the following options: baudrate, download, erase, status, enable .
This format is a protocol supports the MediaTek MT3339, a GPS chipset that shipped around 2011 that has internal logging capability. It is the core of at least two GPS modules, including the GlobalTop PA6H and the Fastrax IT530. The GlobalTop PA6H module is in turn the heart of the Adafruit "Ultimate" GPS breakout board, popular in the Arduino "maker" world.
It is similar to the mtk and mtk-bin formats for earlier Mediatek parts.
Speed in bits per second of serial port (autodetect=0).
The default is to autodetect the baudrate, but that can take a few seconds. If you know the baudrate of the device it is faster to specify it explicitly.
Only valid when using a USB device as input.
Download logged fixes.
This option processes a set of Locus fixes, by downloading it from an attached USB device or by reading records stored in a normal file.
You might want to disable this option if all you want to do is erase the memory or display the device status. Downloading a large dataset can take several minutes and while that is happening no other device commands can be executed.
Erase device data after download.
This option erases the track log from the device after download.
Only valid when using a USB device as input.
Show device status.
This option displays the status of the device after the download is complete. Status includes firmware version, number of log records in memory, interval between fixes, etc.
Only valid when using a USB device as input.
