Please reference the table for a subset of available commands.
NOTE: The commands provided below are included only as examples. Please refer to the
ST150M User Manual and Unified API for a full description of all commands.
You may enter the commands exactly as described in the table as the interface allows you
to exclude the "AT+" prefix. It is also not case sensitive.

USING THE UART
To use the UART, an application capable of TTY communication over TTL UART interface
should be downloaded. The examples in this guide will reference PuTTY on Windows 10,
which can be downloaded via this link:
While your ST150M Dev Kit is turned off apply leads TTL RX to PO. 24, TX to PO. 16, and GND
to GND. Turn on the Dev Kit and using your serial port at 9600 baud, 8 data bits, 1 stop bit, No
parity, Flow XON/XOFF. You can now send AT commands to your dev kit via the UART.
The following example is utilizing a USB TTL device plugged into a PC running Windows.
1.
Validate that the ST150M Dev Kit is recognized as a serial COM port by the Windows
PC by opening the Windows Device Manager utility and observing the listing under
the Ports (COM & LPT) devices. The ST150M Dev Kit will show up as "USB Serial
Port (COMxx)" where xx is the communications port number. As highlighted in the
example below, the ST150M Dev Kit is on communications port COM9.
2.
Open PuTTY and select "Serial" connection type. Enter the COMxx port for the
ST150M Dev Kit as the Serial line and configure the Speed (Baud) to 9600. Select
"Open" and a console window will open to the ST150M Dev Kit.
