Power meter connection / set up problems

Can anyone sort me out. Thank you in advance. I have a shimano power meter and trying to connect to garmin edge 530. I have gone through shimano Etube app setup, and followed directions on garmin to add sensor. Although sensor is added, no data shows up on screen when riding. Shimano in one place says edge 530 isn’t compatible with Blu le, and other place says it is. Should I be using force vector? Any ideas?
