[Lenovo X1 Carbon] Cannot re-pair BT Keyboard when wrong pairing code is entered
Expected behavior: Re-pairing BT keyboard after cancelling initial pairing should re-open the pairing code prompt
Problem: Re-pairing BT keyboard after cancelling initial pairing does not show the pairing code prompt.
Steps:
- Turn on the system’s Bluetooth (usually turned on by default on boot)
- Try to pair the system with the BT Keyboard via the Bluetooth Settings UI
- When the pairing code prompt appears, input the wrong code and press enter. This should generate a new code
- Press “Cancel” on the pairing code prompt. Notice that the cancel button is not working. ==> Problem
- Press the Esc button on the system’s keyboard. This should close the pairing code prompt.
- Try re-pairing the system with the BT Keyboard via the Bluetooth Settings UI. ==> Problem
- Notice that the connection is loading but the pairing code prompt does not reappear. The system and the BT keyboard cannot be re-paired.
Workaround: When a new code is generated in Step 3, input the correct code. This would successfully pair the system and the BT keyboard. Try rebooting the system after Step 7 to recover the connection.
