I have bought a serial TTL to Ethernet Module- USR-TCP232-T2, but I do not know how to send UDP / TCP data with AT command? The way of sending UDP / TCP data is not described in USR-M0-AT-Command-Set_V1.0.1.pdf.
Please tell me how to send / receive UDP / TCP data.
AT commands work for setting TCP232-T2, you can't transmission data by AT commands
You can download software to setting TCP232-T2 by AT commands.https://www.usriot.com/support/downloads/at-setup-rar.html
Note：bandrate must be same with serial port device
open com---> click +++a ---->send AT commands----->click AT+ENTM
The application will be in Chinese notation.
you can change to English.
