Hi,
I want to use ModBus TCP Master and I got a trouble at mbc_master_start(). I get always an Exception.
I think everything alright until to start the master. I made some status log too. Everything was configured as you can see on the attachment.
I tested with idf 4.3 and idf 4.3.1 an a got the same problem.
Could you help me somebody?
Thank you in advance.
Best regards,
Botond

Hi B.Botond,
Please add the end of table condition to the address table (NULL).
