Just brought 530 and Varia RTL515. I have been trying to pair 530 with RTL515 but failed.
The Varia has entered in pairing mode with LED flashing in purple color. Edge 530 can see the Varia, but when selected, the icon in the upper right hand corner of 530 just spins.
Version of Edge 530 is 7.00
RTL515 can be paired with the mobile App Varia, the version of RTL515 is 1.5.0-132
