Not reading data from RJ45 port #4

Hi,

I have been testing your serial connection on my inverter HYV4K4000-48, but seem to be having limited luck. When using the MPI setting I can see the MQTT reports 0's on all topics. However, if I use any other type like PIP and PCM, there are no topics being broadcast. Is this correct?

I wonder if I have the wrong pinout on my full-size adapter (rs232-TTL) (i.e. the adapter I'm using have the serial connector on the board. I have the mini ones on order.) My wiring is as shown in the image bottom right within GitHub.

If you have any suggestions I would love to hear them.

Thank you Ian

So I seem to be getting ^0⧠ã on the _commandBuffer. Not really sure why this would be the case. It happens on all device types, which makes me think it is a reading issue within the code.

Any pointer would e really helpful about now. :)

hey, the PIP/PCM seems not implementet fully on this fork. i do a rework on another fork, but this supports only the qpigs command, not sure that your inverter replay to this. but you can try it

PIP have now been implemented in this fork and support both PCM and PIP series.
