Flipsky bluetooth module settings

Can anyone walk me through setting up the flipsky bluetooth module with my Flipsky dual 6.6? The problem I’m having is that using VESC tool mobile I can connect to the individual boards just fine but trying to use the master VESC to write settings to both esc’s is not working. I am selecting CAN forwarding (1) in the app, is that correct? If someone could guide me towards a more general VESC tool mobile manual as well, that would help.

What phone and android version are you using?

Everything works well now, I’m using an essential phone running Android Pie.
