MTKutility


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 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

I have posted additional screen shots and short instructional videos on my Google drive. Copy this URL to see them.https://drive.google.com/open?id=0BzPpCDPMQTwEfnlSdW5LTXFfbU0wckZpM2tXbUcxN3JpZnRMeFh1QmdGQ2NuMk90dFhUY00&authuser=0

Please contact me 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 it will not contain XML tags for all the data captured. Use the PC app bt747 to create a GPX file from the binary (.bin) download.

Version 2.5.4
bug fix

Version 2.5.3
Revised the HTML version of the SETTINGS screen to improve useability and made it the default for small screen phones (less than 480x800 pixels). Screen size is no longer a restriction on phones with Android 4.0 or newer. Testing for this was with an LG E430 with a 240x320 3.2" screen. Bluetooth connection to GPS devices is still and issue with some tablets.

Version 2.5.2
SETTINGS tab bug fix

Version 2.5.1
added GPS restart functions to MAIN tab

Version 2.5.0
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 text size configuration to include separate configuration for each of the tabs. Numerous bug fixes.

Version 2.1.0
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.

Version 2.0.2
allow 1 meter by distance recording frequency
minor fixes

Version 2.0.1
fixes NMEA settings not showing on an HTC one phone.

Version 2.0.0
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.

Recent changes:
Version 2.5.5
Changed Bluetooth connect to default to a secure connection and added Preference option to use an insecure connection.

Working great. Settings tab is a lifesaver. Works great for what I need. Only program out there that can change the logging settings.

Works like a charm with my bt747 Does it's job as promised and it is even possible to update AGPS data without the need of a Computer! Three thumbs up!

Buggy for me too (Samsung SM-T700, QStarz BT-Q1000XT I find the potential for this app quite appealing. Unfortunately, it is just not very consistent. I can usually connect via bluetooth without problems. I've only managed to download a .bin file once. Even then, it initially failed. I suspected it may have bee the size. I cleared the bin files, turned on the GPS for a few minutes, then downloaded the resultant .bin. That worked fine, and I could convert it to a GPX file. Otherwise download fails with: Download failed Download aboarted I turned on trace/verbose and just see pretty much the same thing. Sometimes the progress bar will get to 20% or so, and pause, then the message. The log just seems to show a timeout error. This is the last few entries: **** pref_cSize=2048, waiting for 1 PMTK182,8 responses == GPSrxtx: ++++ reading from device, waiting for: PMTK182,8, timeout: 60.0 == GPSrxtx: ++++ readBytes timeout:0.0 read:0 bytes == GPSrxtx: ###### no bytes read from device! **** IOException:java.io.IOException: no bytes read from device! logDnldFragment - logDownload.errorWhileDownloading() logDnldFragment - writeToMainTextArea(Download failed) **** Download aborted logDnldFragment - logDownload.cleanup() logD

Buggy app - qstarz bt-q1000xt 1. Had to connect to device - app needs restart to see gps device. 2. crashing too much often. 3. App freezing/stucking while downloading gps track data. 4. Unable to choose different download folder - it says that folder is empty and there is no ability to select folder, only go back/exit/parent. Overall, give 3 stars and not one because the app has great potential. Hovewer, uninstalled, moved to another app. HTC One X.
