I use it, works very well.
Anyway, Twidosoft don't see bluetooth adapter if it's com port number is bigger than 6 or something like that. I had to manually change adapter com port number from 11 to 2 (Device manager), when I installed it to my computer. (Win XP installed adapter to com 11 first)
Sometimes XP don't see bluetooth adapter, but if you power cycle/reconnect adapter to twido PLC, it will work again.
(For some reason bluetooth pairing don't work allways between win XP and adapter, but after power cycling the adapter pairing works again)
