Hi,



Has anybody ever succeeded with updating V7 firmware from a PDA, a HX4700 specifically?



When I try it, the "Update" button does not become active.



I've tried all 4 COM ports with all speeds, including the one suggested in the manual: 115200.





When flying, I have V7 connected to an OzFLARM and HX4700 with WinPilot. It works very well. WinPilot uses COM1 to communicate with V7 with bound rate of 19200.

Try copying the tools, .dll and firmware to the same directory as the 2577 folder. If the button does not work it is because it is not finding the update tool.
