#8 Qstartz Xtreme 10Hz
Using the BT747 V2.X.2025 (08.01.2018) Version. Build BT747_mdeweerd.2025.20180108130459662
Qstarz descries that it is possible to set different log rates to the 1hz Jumper position:
http://racing.qstarz.com/Products/BT-Q1000eX.html
*3-Level Hardware Switch: 10Hz switch mode is default as 10Hz always. 1Hz switch mode can be adjusted via QstarzGPSView tool to change to 1~5Hz or 10Hz update rate.
Using the 10Hz mode I get an CSV sheet with 10Hz using the 1Hz postion I get an excelsheet with 0.2 HZ. The recoommendet version of the Manufactor QstarzGPSView is form August 2012 :-( and does not change anything,exept the fix rate settings.
Using the device settings fom BT747 "**[x ] time every 1 Seconds" ** does not work. It seem to be resetted by the device., depending on the on/1Hz/10Hz switch.
Would be glad to get any helt, we need teh devices for a scientific research.
Kind regards Knut.

Hi, thank you for notifying about the spam filter - the service filtering for SPAM on BT747 stopped in April, I now removed that.
I think that the device has "Smart mode" - BT747 was not updated for that. As a result parameters are lost when power is lost and possibly when you change the switch.
I do not know if QStarz specialized their command set.
You can try to send the following to the GPS (using Putty, ...):
$PTSI760,1,T01,T01,T01*4B
That should set the logger to 10Hz logging in all modes (Low, medium and high speed - foot, bike,c ar or something like that in one of the apps).
The 01 means 0.1 seconds, so 02 would give 5Hz.
You can query the current setting using:
$PTSI760,0*33
The checksum can be calculated using

If that does not do the trick, then you'll have to sniff the serial protocol to learn about its specifics.
