I am running into a persistent issue on my iPad Air 11″ M2 running iPadOS 18.0.1.
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 0x8d47

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