Diagnostic Hardware Specs: iPad Pro 13″ M4 | OS Version: iPadOS 18.1 | Archive Source: Apple Support Community #256442501
I am running into a persistent issue on my iPad Pro 13″ M4 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 0x2ad2
I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?
