Unable to turn on LED which is connected to RPi GPIO pins ? I am modify sampleapp main.c file and UIManager.cpp file ?

Hi @kadam1!

SDK does not provide any code to operate RPi LEDs but you can implement it on your own. Yes, UIManager is the right place for you to put the code that controls LEDs. You may put any initialization logic or customize implementations in SampleApp/src/SampleApplication.cpp, specifically in initialize() method.

Please let me know if that helps.

I am following sam setup configuration as per below link https://developer.amazon.com/docs/alexa-voice-service/indicate-device-state-with-leds.html

but still it was not working?

Hi @kadam1 , I think the people in the Alexa forums may have more insight on how to help you on this.

You may also want to use WiringPi's utility command gpio to first see if you are able to access the GPIO pins. Look at the examples on how to write to the GPIO directly. In the AVS document, I believe WiringPi pin 0 and 1 are (GPIO0 and GPIO1) respectively.
