 === UART RX/TX Example ===
 
-This code was provided by a Texas Instruments (TI) employee on the E2E Support forums.
+This sample example code was provided by a Texas Instruments (TI) employee (Prashanth S) on the [https://e2e.ti.com/support/wireless_connectivity/proprietary_sub_1_ghz_simpliciti/f/156/p/586620/2154741#2154741 E2E Support forums] - (filename download on the forum post is: 4034.uartRxTx_CC1350_LAUNCHXL_TI.zip). 
+
+At a high level, this example allows for you to type from a keyboard to an open UART on each side and the data will be sent to the other side.
+
+One single project is designed to do TX and RX (one firmware file).
+
+Download the pre-compiled firmware here:
+[http://dev.gateworks.com/gw16122/uart-rx-tx-example-firmware/ uartRxTx_CC1350_LAUNCHXL_TI.out]
+
+Using a Windows or Linux desktop/laptop PC, flash this firmware to the GW16122.
+
+Connect the GW16122 to the desired system where you will then open the UART communication.
 
 This example exposes 2 serial ports to the host that the GW16122 is connected to.
- *Linux Example 
-  * /dev/ttyACM0
+ * Linux Example 
+  * /dev/ttyACM0 (use this first UART)
   * /dev/ttyACM1
-
-This example code 
+ * Windows Example
+  * COM6 (use this first UART)
+  * COM8 
+
+Open the serial port /dev/ttyACM0 on the host using a terminal program of your choice, such as screen / picocom or Putty using 115200 baud rate and turn on local echo.
+
+You can type the data you want to send, but ***must*** press the 'Enter' key to actually send the data.
+
+Type a message on the console on the TX side, like so:
+{{{
+hi, hello world!
+}}}
+ 
+
+The other end will print the received data with a string like so:
+{{{
+rx data: hi, hello world!
+}}}
+
+This example code uses the following LEDs on the GW16122:
  * LED D1 toggles green when it sends
  * LED D2 toggles red when it receives
 
+The RF is at 500 kbps by default but can be adjusted in the source code.
