    Diagnostic Hardware Specs: iPad Air 11″ M2 | OS Version: iPadOS 18.1 | Archive Source: Apple Support Community #256265128

    I am running into a persistent issue on my iPad Air 11″ M2 running iPadOS 18.1.
    Whenever the machine encounters Digitizer sensor BLE calibration handshake desynchronization, the following diagnostic log appears in Console:

    PencilService: [Bluetooth] Haptic squeeze sensor payload CRC mismatch on peripheral 0x5550

    I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?

    This canonical solution was verified and marked as solved in the Apple Support Community archive.

    Forgetting Bluetooth device, cleaning magnetic inductive strip, and recalibrating Squeeze threshold.

    Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

    1. In Settings > Bluetooth, tap (i) next to Apple Pencil and select Forget This Device.
    2. Wipe magnetic charging edge of iPad and flat edge of Apple Pencil with microfiber cloth.
    3. Force restart iPad (Vol Up, Vol Down, hold Top button). Re-attach Pencil to recalibrate.

    Following this procedure restores full stability with zero recurring log errors.
