do you now how to transfer telemetry data from FRSKY Tx to laptop via USB ?
Thanks,

I am not sure if you are asking about the actual connections neccessary, or the methods to extract the actual data after you have the connections in place, so I will try to answer both.
For the hardware.
Depends on if you have the FrSky USB cable, or the FrSky serial cable. If you have the serial cable you will need either a serial port on your computer, or a USB to Serial adapter cable. This adapter is typically very similar to the one that is built into the FrSky USB cable. And you will probably need a driver. The FrSky USB cable should just connect directly between the computer and the Tx module, but might need a driver (I don't have this cable so cannot say for sure)
There is one more route (the one I actually use) Is to have a serial to bluetooth bridge chip connected to the Tx at all times, then i use bluetooth on my computer, or on my cellphone to connect to the FrSky system.
Software:
When all that is in place, you can use the programs from the FrSky webpage to set alarms, and also see the values of the analog channels.
(I don't know if the FrSky software now also supports its HUB data, but it probably will at some point if it doesn't already)
If you need more detailed telemetry data (user data etc), you will have to retrieve the serial stream, and parse it as the documentation states. (I would only recommend this to programmers and people that have an interest in learning to program to start this path though)
The stream can also be read in the windows application Hyperterminal, or third party software like Putty without programming skills, however the raw data is encoded, so you still need to do work to have the stream make sense.
Hope that this helped you
