问题
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.
回答1:
BLE devices will appear in one of three cases -
- An app has an active connection (the device will be listed under "My devices")
- An app has a pending connection to a device that has gone out of range (the device will be listed under "Other devices")
- 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.
