GPS Data Logger Software - BT747

Hello, I've got Qstarz Q-1000X; before I logged with Wintec WBT-200. I want to log RMC and GGA every 1 second, and I want to log GSA and GSV every 5 seconds. I am able to receive these protocolls in this manner when using Qstarz as bluetooth mouse (switch shows NAV). But I fail when switch shows LOG. I already received all wished protocols, but all at every second! And because GSV creates 4 lines used storage increases very fast. I think I would success if I am going to change flash settings and update the flash. Did nayone already tried ist? bt747 shows zero attempts to flash mouse.
