CRC mismatch

[xeni1983]

I receive this error
Caused by: com.digitalpetri.modbus.exceptions.ModbusException: CRC mismatch
It is any possibility to ignore CRC?

At the moment, no, but I think this could be added as some kind of configuration option.

It can be dangerous to ignore, the packet could be incomplete and fail to subsequently parse, or it could just silently have incorrect data in it.

Okay, something that could work in #88.

Usage would be something like:

    ModbusClientConfig config = ...;
    ModbusRtuClientTransport transport = ...;
    
    var client = new ModbusRtuClient(config, transport) {
      @Override
      protected boolean verifyCrc16(ModbusRtuFrame frame) {
        if (!super.verifyCrc16(frame)) {
          resetFrameParser();
        }

        // ignore CRC mismatches, return true to continue processing
        return true;
      }
    };

Thank you. I have an equipment that has a specific CRC validation. That's why I want to bypass verify CRC

[kevinherron]

Does it not expect a different CRC on the request frames too, then? How does this work now?

It is ok now. I receive data from sensor
