Dear Hans Adams, Thank you for using our product. To connect two CSW-H85K units in AT command mode, you could refer to page 13 and 14 in AT Command Mode - Application Note: http://www.eztcp.com/en/download/pds_files/an_atc_mode_en.pdf For example, on device #1 (TCP Server), the AT command procedure can be as below: >at+plip=YOUR_TCP_SERVER_IP >at+plp=YOUR_TCP_SERVER_LISTENING_PORT >ata After you enter "ata", this unit (TCP Server) will start listening to TCP connection request. Note that, on command line, there will be no response message (you should avoid entering "ata" command more than one time). Next, you can setting configuration for client device. On device #2 (TCP Client), you may input command as below: >at+prip=YOUR_TCP_SERVER_IP >at+prp=YOUR_TCP_SERVER_LISTENING_PORT >atd Here, if the TCP connection is established successfully, the "CONNECT" message will be displayed on command screen of both devices. Note that after using AT command to config IP and port on devices, you should use command "at+pwp" to save those setting values to products, so that the setting will be saved even after reset (refer to page 4 in AT Command Mode - Application Note). And also, it could be better if you can make sure that you are using latest firmware for CSW-H85K. You may find the latest firmware, v2.4, at the link below: http://www.eztcp.com/en/download/pds_view.php?bbs_id=15&page=1&cid=280 If there is still any problem, please feel free to contact us.
