I have a D3 Plus which also has a bluetooth app. I know this works for me: Keep your phone bluetooth off. Open the DYU APP. When it loads and searches it will ask permission to turn on bluetooth. Wait until you see the DYU app load then click YES to allow bluetooth. Good luck...

Also if the d2f doesn't have blue tooth how can I gps track if it gets stolen also how do I change the speed settings without the app come on guys I bought my d2f from wish it was suppose to be a d2 I the every dyu they sell are d2fs and they charge different prices this is very deceiving

all our ebikes don't have GPS not only D2F. Our GPS only work in China. D2F withour APP can't change the speed setting.
