QSTARZ (MTK chipset) support please

1) GNSS Commander is a great app and works very well with Bluetooth, however I need USB support for my GPS.

I have the QSTARZ 818XT GPS which uses the MTK II chipset (see link for full specification) and gives 10Hz update rate that I need. It supports both Bluetooth and USB from one device, it works well, and is very popular in motorsports, but there are no Android apps to support USB for it. The company says to use QstarzGpsView v1.2.24 for USB, but that is only a Windows app and driver (available here).

On some Android devices Bluetooth has pairing problems, drops connection, or is slow, so USB is much better. I use your app with "mock locations" enabled.

I tried all of the USB options in GNSS Commander and none work, so I am requesting to please add support for it because there are many GPS devices using MTK.

2) If MTK support over USB is impossible, can you recommend another 10Hz GPS that you know will work over USB with your app? The ONLY one I can find that might work is this one because it uses MTK3339 chipset but uses FT232RL output. Will that work using your FTDI option in the app?

Vielen Dank!

as you already said (and tested) the MTK chipset is currently not supported in the GNSS-Commander app.
Sadly i do not have a device with MTK-USB chipset, so it will be pretty hard for me to test any modifications.

At the moment i do not have much time to change anything in the app code,
so let me think about supporting MTK in the future...

Hi Markus,

Thank you for the quick response. If you can make some time, and are willing, I am happy to send you my QSTARZ818XT to use when modifying and testing your code. Are you willing? I can mail from here or I am traveling to Germany in June for work, it would be easy for me to drop it in the Post either way.
