1. My IPOD Mini was to old the run the apple app 2. I never used any android app 3. I have an issue with one of my Hornby locos with a TTs chip the runs away if address 3 is selected. 4. I ran the TXS chip on the rig out of the box having removed the above loco of the track it ran ok. 5. The problem arose when I changed the address from 3 to 821 all appeared okay. 6. When I tried to read the chip CV’s back no response from the chip. 7. This is what I reported over the phone and got the weird reply about reset codes etc. 8. Let put this post to bed now Its gone back to Margate Mod note - locked as requested.
