Hello,
I am not yet able to flash my old frsky sensor hub with an ordinary ftdi USB/rs232 modul.
Maybe there is a "strange" protocol that you should have to use/buy the original frsky flash Modul???!!!
I see no UID number in the frsky flash program,
the configuration of the ftdi modul with WIN XP is OK!!!!!
Thanks in advance.

Re: How to flash frsky Sensor hub with ftdi modul
You need an adapter that uses RS232 levels, not TTL ones. Or a TTL one that has both signals inverted.

THX Kilrah,
ehm...
RS232 level is around zero +3-15V to -3 - -15V..
ftdi goes from 5V to 0V and vv.

..uups..to fast on the send button!!
Anyway..to invert TTL means only to do 5V>>>OV...OV >>>5V...
I did some 7404 Inverter to the output of the ftdi232...successless...

I could fix this problem not with a 7404 inverter but with a RS 2323 level converter. THX anyway!
