Note: Even if you do not support GET_LOCK_PIN, the OLA responders tests try a "GetLockPinWithData" and claim a
"Response: RDMResponse:, Get NACK Unsupported command class, PID: 0x0640"
as
"Failed: expected one of:
CC: Get, PID 0x0640, NACK Format Error
CC: Get, PID 0x0640, ACK, fieds [], values {}"
This may be misleading. You simply cannot generate any answer when you don't support that PID or command class.
It reminds me of the question:
"Which part of 'NO' don't you understand?"
