    bleprofile_LED functions, how to change the o/p pin polarity?

    NiVa_4337911

      Hi,

      I am working with the find_me application provided in the users guide project ("Getting Started with EZ-BLE WICED Modules", https://www.cypress.com/file/396961/download).

       

      How can we change the bleprofile_LEDOff() and bleprofile_LEDOn functions polarity (0 => OFF, 1 => ON) ?

       

      I changed the following in profile.h

       

      #define GPIO_SETTINGS_LED  

      (GPIO_OUTPUT | GPIO_INIT_LOW | GPIO_LED)

       

      and in find_me.c

       

      gpio_configurePinWithSingleBytePortPinNum(GPIO_PIN_LED, GPIO_OUTPUT_ENABLE, GPIO_PIN_OUTPUT_LOW);

       

      but I guess it only changes the initialization value.

       

      Another problem is the LED is not turning on or blinking even though the On/Off functions are called (use ble_trace functions to confirm this). I used "clean" make target after changing the platform header files.
