i have just noticed my 520 has two Bluetooth connections to my iPhone (as seen in iPhone settings menu) - these are BT_Edge 520 and BLE_Edge 520. Do I need both - are they each doing something different, and will I have a problem if I only have one of these connections?
I only just noticed this today after I had some issues and had to repeatedly go through the pairing process to reconnect my 520 to my iPhone 6 (which I have now done).
Thanks in advance,
Matt
