Please give me some time to translate it. We have translated into English the parts of the I/O port description and the Internal register description that seem to correspond to your question. (Some parts are incomplete, such as references n…

Hi Riki, I was able to get some data through TCP connection via Utility. That's good. It looks like your mission has progressed a bit. By the way, I tried the Linux version of SiTCP Utility (ver. 0.7.4) on UBUNTU18.04. After instal…

Hi Riki, I'll also try to verify the Linux version of SiTCP Utility tonight. I'm going to try this one on a PC (UBUNTU20.04LTS, I think) and SOY2. SOY2, in demo mode, will count up the data of an 8-bit counter while establishing a connection wi…

Hi Ioannis! Is there anything I can cross check, or are you aware of such a behaviour? Not particularly, but I'm sure you can understand from the samples. https://github.com/BeeBeansTechnologies/SiTCP_Sample_Code_for_AC701_SFP https:…

Hi Ioannis! I am writing in order to ask if there is to test the SiTCP core without purchasing a full license. Yes, it is possible. I am interested in trying to see if I can access a single device and check if I can send/receive …
