Hello everyone,

I need help with the basic schematic of WS6318 and how to communicate it through UART with AT command.

My application is to make calls and send sms.

What I have tried so far:

#Schematic wise:  
-VBATT = 3.3V, LED on WISMO\_READY, ON/~OFF and VCC\_2V8  
-Antenna connection.  
-SIM card connection.

I want to use UART over terminal to know how my AT command works on it.

Please suggest how should I proceed.

I want to learn this module since its the smallest module available.

Thanks and Regards  
SRPUNCH

Hi,

The AT command guide you can find in [source.sierrawireless.com/resour … nd\_manual/](http://source.sierrawireless.com/resources/airprime/software/airprime_ws6318_firmware_at_command_manual/)

you can use hyper terminal to communicate with the module to send sms and make calls…

Let me know if some more doubts…!
