Thanks for the feedback.
IMHO, the device does not support the usual logger commands as the log is written in CSV format on the microSD and not to an internal flash component.
So you can use BT747 to see the usual MTKII parameters and configure some of these. And you can use BT747 to convert the CSV files.
I do not know if it is possible to retrieve the CSV files using the USB connection.
