Spirit System

hi i was trying to update the gtr to 3.4 but my ds-12 does not read it anymore

this happened after i updated transmitter on jeti studio

I have a ds-24 and works ok. But I want to use my ds-12 spirit edition for my heli

... after updating the DS-12 in Jeti Studio: you most probably have to (again) copy the Spirit integration files to the DS-12. the Jeti DS-12 update is overwriting the integration files with another (older?) version - just download integration 3.4.0 and copy it. should work again...
