May be this is not the correct place but I give it a try:
Hello can someone please help me with the following:
I want to communicate with a MODBUS TCP client to a ESP8266 ESP01 card.
I use the sketch of http://en.trialcommand.com/blog/esp8266 ... libraries/
This works, however my Modbus TCP client throws an exception
"Incorrect length in response"
This happens when I send "node.writeMultipleRegisters(xx,yy)" the client should respond with an acknowledge, I have the impression that this acknowledge message does not have the correct length.
Might this be a library issue?
Your help is very much appreciated.
If this is not the write place to ask this I apologize please direct me to the correct one, Thanks!
