LED blinking on CYBLE-013025 (Chip 20737)

[tiko_2703136]

Hello,

maybe someone has a hint for me. I try to get the LED to blink on my CYBLE-013025-EVAL.

I downloaded the Wice Smart SDK 2.2.3 and the Platform files for CYBLE_013025_EVAL.

I got my module running with Advertising, but I cannot get the LED to blink.

What I did:

Created the GPIO Config

const BLE_PROFILE_GPIO_CFG myapp_gpio_cfg =

{

    /*.gpio_pin =*/

    {

    GPIO_PIN_LED,     // LED GPIO, optional to provide visual effects

    -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1 // other GPIOs are not used

    },

    /*.gpio_flag =*/

    {

    GPIO_SETTINGS_LED,

    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0

    }

};

Called the bleapp_set_cfg with my gpio function (myapp_cfg was also set to NULL to see if the led_enable flag makes a difference -> It didn't).

bleapp_set_cfg(NULL, 0, (void*)&myapp_cfg, NULL, (void*)&myapp_gpio_cfg, myapp_create);

I called gpio_configurePin(GPIO_PIN_LED / 16, GPIO_PIN_LED % 16, GPIO_OUTPUT_ENABLE, 1); in myapp_create.

I tried bleprofile_LEDOn(); -> LED is off

I tried bleprofile_LEDBlink(250, 250, 100); -> LED is off

Has someone an idea what I can do to get the LED blinking? The PDF I found only mentioned configuring the gpio pin and calling the LED functions.

Best regards,

Tim

Please use the GPIO function to control the LED.

The eval board uses P14 for LED.

1. Don't set up P14 in your BLE_PROFILE_GPIO_CFG structure.

2. Drive P14 low when you want to turn it on.

void application_create(void)

{

     // all other application initialization

     // Drive P14 low. If the LED is hooked up right, it will turn on

     gpio_configurePin(14/16, 14%16, GPIO_OUTPUT_ENABLE, 0);

}

Thanks for the help! This worked for me.
