forget a BLE device in a iPhone 6 (8.1.3)

Question

I don't know how to forget a BLE device in my iPhone device. Going to Settings -> Bluetooth page , I see the list of Devices, but I don't see any option to forget it.

Answer 1

BLE devices will appear in one of three cases -

1. An app has an active connection (the device will be listed under "My devices")
2. An app has a pending connection to a device that has gone out of range (the device will be listed under "Other devices")
3. The device is paired (bonded) (the device will be listed under "My Devices" whether it is currently connected or not)

Only case 3 will give you the ability to "forget this device" - as "forget this device" really means to remove the encryption keys that were used in the pairing (bonding).

If case 1 or 2 apply then if you kill the app that has the connection/pending connection then the device will be removed from the list.
