use it

[xietuliang]

I have added the following code in file "ModBus/src/Request.h". When I want to use file "ModBus/src/SerialConnection.h" to communicate , I find there is no way to establish a bound connection between "modbus::PDU" and "modbus::Request".And I have to use this code "void SerialConnection::send_request(Request& request)" to send a request.

void Request::set_pdu(std::unique_ptr<PDU>& pdu_ptr) {
	pdu_ = std::move(pdu_ptr);
}

I'm a rookie. Please forgive me if I said something wrong.

Hi Sorry for the long response.
Looks like that you need to use one of ReadHoldingRegistersRequest classes that are inherited from the Request class and have access to the internal field of _pdu.
And use ModbusSerialTransaction to execute transaction.
