Edge 530 with iPhone 11/iOS 13 not pairing

It took me quite a few tries to get it paired, here’s what I can offer, for what finally worked, for me.

All the usual stuff first:
1 – Completely remove all of the Edge 530 entries from the iPhone's Bluetooth screen
2 – Remove the iPhone entry from the Edge 530
3 – Power cycle the iPhone and the Edge 530
4 – Cycle the Bluetooth and Wi-Fi off and back On, on both devices (I know, seems odd, but give it a try)
5 – Now power off the Edge 530, open the Garmin Connect app on the iPhone 11 and click the + in the upper right corner, or go to the Garmin Devices menu and then power on the Edge 530.
6 – Now, when the Edge 530 is presented, initiate the add device strictly from within Garmin Connect. This worked for me.

It seems like what was causing me issues on previous tries was that I was first going into the iPhone Bluetooth screen and pairing one of the Edge 530 Bluetooth instances, and then trying to finish via Garmin Connect and that was failing every time. Both BT entries look the same now (once it's paired), but on my Edge 520 there was a BT and a BT-LE entry.

Good Luck with it.
