Just saw your product on the digikey site. I would like to confirm if it will meet our needs.
Currently we use a PC/linux base TCP client program to communicate (send/receive data) with a UART to ethernet module (the lantronix xport xp100100G-05R) . The module is connected to one of the 3.3V processor UART ports and acts like a serial to ethernet link.
The communication does not use any ‘AT’ commands, just sending/receiving hex bytes.
Can i use the wiz750sr similarly, and do you have examples of how to set up the module.
