I am using NFC Cockpit to check LPCD operation.
When a card or metal object is brought near, the following log will be output
INFO:LPCDServicePN5190:Perform LPCD
INFO:LPCDServicePN5190:Load detected
INFO:LPCDServicePN5190:LPCD Calibration
INFO:LPCDServicePN5190:LPCD Calibration successful
However, when the iPhone is brought close, an error is output.
WARN:LPCDServicePN5190:Hard resetting the IC. Because LPCD aborted without Card Detection.
Perhaps the problem is the LPCD assistance on the iPhone, but I would like to know how to solve it!
