Hello Regunath

What is the code that you have controlling the LED blinking?

we not yet done any coding for controlling the LED blinking. Just follwed the exosite "Connected LaunchPad Out of Box Experience" Video. Its available at "ti.exosite.com/.../2213423599".

Hello Regunath

For the device to blink the LED, there must be some code required in the TM4C device. Are you sure that there is a code flashed to the device? A simple check would be to connect LMFlashProgrammer and perform a blank check. If blank check passes then there is no code and that is why no blinking of the LED's.

If the blank check does not pass, then I would suggest flashing the qs_iot example binary file to the device and then check on the UART console if the IP address is acquired.
