MTKutility is a maintenance utility for Bluetooth capable GPS devices that use the MTK or MTK II (GPS) chip. You can:
* configure the information recorded in the log file
* configure the track point recording frequency
* download the track points to a binary format file
* generate of a GPX file from the download
* store the binary and GPX files on your external SD card
* update the Assisted GPS (AGPS) data
* configure screen text sizes
There is an alternate settings screen that can be be selected in app settings for phones that cannot display the default settings screen.
Please contact the author if this app does not work with your MTK GPS device. Since the initial release the app has been modified to work with both GPS receivers and GPS loggers that do and do not have AGPS. The app has extensive execution tracing that can be turned on to assist with determining why the app isn't working.
This app also has crash logging. Please look at the app information for details on crash reporting. Emails with questions, suggestions and issues are welcome. Email to [email protected]
Download failures on large track point downloads - 50,000+ points - are a known issue. Seems to be a Bluetooth communication issue with some device combinations. AGPS update on a Qstarz BT-Q1000XT also remains unresolved. The GPX file created is good enough to show tracks on a map, but the quality of the data is suspect. If your intended use of the data is geotagging, use bt747 to create a GPX file from the binary (.bin) download.
SETTINGS tab bug fix
Added a tab to make creating GPX files from previously downloaded binary files possible. Created an alternate SETTINGS tab for phones that cannot fully display the check-box layout. Expanded test size configuration to include separate configuration for each of the tabs. Numerous bug fixes.
Enabled GPX file recreation by changing this process from a check-box on the Download screen to a button that launches file selection and GPX file creation. The location of the binary download and GPX files can be set to separate folders on internal storage or the external SD.
allow 1 meter by distance recording frequency
fixes NMEA settings not showing on an HTC one phone.
extends the range of GPS devices by distinguishing between GPS receivers and GPS loggers, and the presence of AGPS data. Main screen font sizes are now configurable to resolve field value truncation on phones.
SETTINGS tab bug fix

Numerous bug fixes. Please give MTKutility another try if you abandoned it over performance issues.
New tab to create GPX files from previously created binary files and an alternate SETTINGS tab layout for phones with smaller screens. Separate Text size configuration for all tabs.
